Cloud backup (also called online backup) is a service that copies data from computers, servers or software-as-a-service applications to storage operated by a third party over the internet, so that files can be restored after hardware failure, theft, accidental deletion or ransomware. Unlike file-sync services, a backup service keeps earlier versions and deleted files for a defined retention period, and it runs on a schedule or continuously without the user moving files by hand.
This list covers thirteen services available in November 2026, from unlimited personal computer backup (Backblaze, Carbonite) and multi-device plans (IDrive, SpiderOak One) to business endpoint backup (CrashPlan) and backup of Microsoft 365, Google Workspace and Salesforce data (Keepit, Druva, Microsoft 365 Backup, Own). The United States Cybersecurity and Infrastructure Security Agency advises organisations to maintain offline, encrypted backups of critical data and to test them regularly, because many ransomware variants try to find and delete or encrypt reachable backups.
Prices, retention terms and plan limits below are taken from each vendor's own pricing or product pages as consulted in November 2026. On-premises and hybrid backup platforms sold mainly to data-centre teams are covered in the separate list of backup software.

What is cloud backup
A cloud backup service has three parts: a client (a desktop agent, a server agent or an API connector to a SaaS application) that selects and reads data; a transfer step that normally encrypts and compresses the data before it leaves the device; and vendor-operated storage that keeps multiple versions according to a retention policy. Restores are done from a web console, from the client, or, for large volumes, by shipping a physical drive; Backblaze and IDrive both offer the latter.
How it differs from adjacent categories
Cloud storage services such as Dropbox or Google Drive synchronise a working folder; when a file is deleted or encrypted locally, the change is usually propagated. A backup service keeps the earlier copy for a defined period. Object storage (for example Backblaze B2 or Amazon S3) is raw capacity sold per gigabyte; it becomes a backup only when combined with software, which is the model used by Arq, where the buyer licenses the app and points it at storage of their choice. Backup software for data centres (image-based backup of virtual machines and databases) overlaps with business cloud backup but is typically deployed and managed by the customer. Disaster recovery services go further and restart workloads in a secondary site rather than only returning files.
Scope of this list
Entries were limited to services where the vendor operates or resells the cloud storage as part of the subscription, or where storage is an integral, priced option. Pure object-storage providers without a backup client are excluded.
History and market
Consumer online backup predates the SaaS era by more than a decade. SpiderOak states that it has offered its service since 2007. Backblaze, whose founders started the company in a Palo Alto apartment, sells flat-price unlimited computer backup alongside B2 Cloud Storage and is publicly traded under the ticker BLZE.
Consolidation
The category has consolidated through acquisitions by larger software groups. Carbonite has been part of OpenText's cybersecurity business since 2019. CrashPlan, which began inside Code42, announced its separation from Code42 Software in August 2022 in a transaction the release headline attributes to Mill Point Capital, and now describes itself as an independent company. Salesforce signed an agreement on 5 September 2024 to acquire Own Company, a Salesforce backup specialist, for approximately US$1.9 billion in cash net of the roughly 10% stake it already held, and completed the deal on 18 November 2024.
The shift to SaaS backup
As e-mail, documents and customer records moved into Microsoft 365, Google Workspace and Salesforce, a second market formed around backing up SaaS tenants. Vendors such as Keepit and Druva license per protected user rather than per gigabyte, and Microsoft itself now sells Microsoft 365 Backup on a consumption basis of US$0.15 per GiB per month. No market-size figure from a named research firm was consulted for this list, so none is given.
Key features to compare
Retention and version history
Retention determines how far back a restore can reach. Backblaze keeps 30 days by default, one year at no extra charge and indefinitely for US$0.006 per GB per month on files older than a year; IDrive retains up to 30 previous versions of each file; Keepit's editions are differentiated by recovery windows of up to 5 or up to 10 years.
Encryption and key control
All services encrypt data in transit and at rest, but they differ in who holds the key. SpiderOak One encrypts on the device and states that it cannot read files or metadata; IDrive and Backblaze offer an optional user-defined or private key. A private key protects against provider-side access but makes the data unrecoverable if the key is lost.
Capacity model
Plans are either unlimited per computer (Backblaze, Carbonite, CrashPlan endpoints), fixed-capacity pools shared across devices (IDrive, SpiderOak, Acronis), or metered per gigabyte (Microsoft 365 Backup, Arq Premium overage).
Device and workload coverage
Personal plans may cover one computer (Carbonite) or unlimited devices (SpiderOak). Business services add servers, NAS devices and SaaS applications; IDrive's single account covers computers, mobile devices, Microsoft 365, Google Workspace, Salesforce, Dropbox and Box.
Restore options
Large restores over the internet can take days. Physical restore by mailed drive (Backblaze, IDrive Express) and bulk restore throughput guarantees (Microsoft quotes 1 to 3 TiB per hour for express restore points) matter more than upload speed in a real incident.
External drives
Some plans exclude attached drives. Carbonite includes one external drive only on Plus and Prime, whereas IDrive includes external hard drives on its standard plans.
Administration and compliance
Business buyers compare single sign-on, role-based access, legal hold and audit logs. CrashPlan lists legal hold, retention policies and audit logging in its Enterprise endpoint tier; Backblaze puts OIDC single sign-on in its Enterprise Control tier.
Pricing models
Four billing models are common among the entries. Flat per computer: Backblaze charges US$9 a month or US$99 a year for unlimited personal backup, and Carbonite's one-computer plans run from US$71.99 to US$121.49 for the first year. Capacity tiers: IDrive Personal starts at 5 TB for US$6.99 a month billed yearly, SpiderOak One at 150 GB for US$69 a year, and Acronis True Image Advanced at US$57.99 a year with 50 GB to 500 GB of cloud storage. Per user or per seat: CrashPlan Small Business costs US$7.33 per user a month for endpoints and US$2.50 per user a month for Microsoft 365 or Google Workspace, while Keepit and Druva publish no prices and quote per seat. Consumption: Microsoft 365 Backup bills US$0.15 per GiB per month with free restores.
Two practices affect real cost. Several vendors show first-term discounts that do not apply at renewal: Carbonite states that its offer is for new customers and not renewals, and IDrive notes that standard pricing applies from the second year of its two-year offer. pCloud is the main entry selling lifetime licences, priced in euros. Buyers should compare second-year prices and any add-ons such as extended retention, extra storage or courier restores.
How to choose
Individuals with one or two computers
Backblaze offers the simplest unlimited plan with a free one-year version history; Carbonite is an alternative for buyers who want antivirus bundled (Plus and Prime include Webroot). Users who want to choose their own storage location or keep several destinations can use Arq.
Households and multi-device users
IDrive Personal and SpiderOak One both pool storage across an unlimited or large number of devices, including Linux machines. Acronis True Image combines local disk imaging with cloud copies for up to five PCs or Macs.
Small businesses
CrashPlan Small Business (under 250 employees) bundles unlimited endpoint storage with optional server and Microsoft 365 or Google Workspace protection. IDrive Team and Business plans suit firms that want one console for computers, servers and SaaS data. Synology C2 Backup is a fit for Synology NAS users.
Organisations protecting SaaS data
Microsoft 365-centric tenants can use Microsoft's native service, which keeps backups inside the Microsoft boundary, or an independent copy from Keepit, which stores data in its own data centres rather than a public cloud. Druva covers SaaS, endpoints and data-centre workloads under one platform, and Salesforce customers can use Own, now part of Salesforce.
Privacy-sensitive users and EU data residency
SpiderOak One's client-side encryption, pCloud's Swiss company base, and Synology C2's choice of European or North American residency are the relevant differentiators.
Methodology
Entries were selected from services that include vendor-operated cloud storage as part of the subscription (or as a priced, integral option), operate under the stated name in November 2026, and publish product information on their own websites. Ownership changes were checked against company or acquirer statements: Carbonite is listed as an OpenText brand, CrashPlan as an independent company since its 2022 separation from Code42, and Own under Salesforce.
The order is an editorial assessment, not the result of hands-on testing or user ratings. It weighs four verifiable criteria: breadth of devices and workloads covered; length and transparency of version retention; availability of user-held encryption keys; and whether prices are published. Services for individual computers and small businesses with published prices and long retention appear first; SaaS-focused and enterprise services with quote-based pricing follow, because their pricing and retention could not be compared on the same basis. Prices are list or introductory prices shown on official pages when consulted in November 2026, exclude tax and may differ by region. Customer counts and performance figures are the vendors' own statements.
The list
1
Unlimited, flat-price backup for Mac and Windows computers
Best for: Individuals and small teams wanting unlimited backup at a flat price
Backblaze Computer Backup is the original product of Backblaze, a remote-first company listed on Nasdaq under the ticker BLZE. The service backs up a Mac or PC automatically with no limit on data volume and, according to the pricing page, no restrictions on file type or size. Backblaze states that it serves 500,000 customers in more than 175 countries and that 188 billion files have been restored. Personal backup costs US$9 a month, US$99 a year, or US$7.88 a month on a two-year term. Version history is 30 days by default, one year at no extra cost if enabled, or unlimited for US$0.006 per GB per month on files older than a year. Data is encrypted with an AES-128 key protected by a 2048-bit public/private key pair, and users can add a private encryption key. Large restores can be shipped on an encrypted USB drive that is free if returned within 30 days, and web restores are delivered as zip files of up to 500 GB per request. A Business tier adds multi-user administration, and Enterprise Control adds OIDC single sign-on and restricted restore access. The service backs up whole computers rather than SaaS accounts or servers, which separates it from the business-platform entries below.

Multi-device backup with large storage pools and SaaS backup in one account
Best for: Households and small firms backing up many devices to one pool
IDrive is a backup service run by IDrive Inc. that lets one account protect multiple PCs, Macs, Linux machines, iPhones, iPads and Android devices, plus external hard drives. Unlike unlimited per-computer services, IDrive sells storage pools: a free Basic plan includes 10 GB, IDrive Personal starts at 5 TB and runs to 100 TB, and Team and Business plans scale to hundreds of terabytes. The client performs incremental, compressed backups, provides snapshots for point-in-time recovery and retains up to 30 previous versions of each file. Files can be encrypted with 256-bit AES using a user-defined key that IDrive states is not stored on its servers. The IDrive Express service ships physical storage for backup or retrieval, which the company says takes less than a week. Beyond computers, the same subscription family covers Microsoft 365, Microsoft Entra ID, Google Workspace, Salesforce, Dropbox and Box backup, servers such as SQL Server, Exchange, Hyper-V and VMware, and Synology or QNAP NAS devices as an add-on. A "true archiving" option keeps deleted local files in the account until the user runs a clean-up. The breadth of the feature list means the interface is denser than single-purpose services.
Key features
- Unlimited devices in one Personal account
- Snapshots and up to 30 file versions
- Optional private 256-bit AES key
- IDrive Express physical shipment
- Microsoft 365, Google Workspace and Salesforce backup

Business endpoint backup with unlimited versions and bring-your-own storage
Best for: Small and mid-sized businesses protecting employee laptops
CrashPlan is an endpoint and server backup service for businesses. It began as a product of Code42 and now describes itself as an independent company; its separation from Code42 Software was announced in August 2022, in a release headlined as an acquisition by Mill Point Capital. CrashPlan today sells Small Business plans for organisations under 250 employees and Enterprise plans above that threshold. The Small Business endpoint plan covers Windows, macOS and Linux with unlimited cloud storage and unlimited versions, and lets users restore and migrate devices without an IT ticket. Separate plans cover Windows and Linux servers with 250 GB of pooled storage per server, and Microsoft 365 or Google Workspace with 50 GB per user. The Enterprise tier allows customers to store backups with CrashPlan, Azure, AWS, Wasabi, Backblaze or their own S3-compatible storage, and adds single sign-on, delegated administration, immutable copies, legal hold and audit logging. CrashPlan is also marketing a transition plan to Code42 Endpoint Backup customers, whose product it says shuts down at the end of 2026.
Key features

Unlimited single-computer backup from OpenText, with optional antivirus
Best for: Single-computer users who want backup and antivirus from one vendor
Carbonite is an online backup brand that has belonged to OpenText's cybersecurity business since 2019, alongside Webroot, MailStore and Hightail. Its personal plans back up one computer with unlimited, encrypted, automatic cloud storage for a flat price. Three tiers are offered: Basic, which covers one computer; Plus, which adds one external hard drive, automatic video backup and Webroot antivirus; and Prime, which has the same device coverage as Plus. Courier delivery of recovered files is available for an additional fee. Carbonite states that customers who are infected can call support within two weeks to restore pre-infection versions. Clients run on Windows 7 or later and OS X 10.10 or later. A 15-day free trial and a 30-day money-back guarantee are offered. The published prices are introductory: Carbonite states the discount applies to new customers only and not to renewals, and the list prices shown are 25% to 40% higher. The plans page is internally inconsistent on encryption strength, quoting both 256-bit encryption and "128-byte protection", so buyers needing a specific cipher should confirm it with the vendor.

Disk imaging and cloud backup for up to five PCs or Macs
Best for: Users wanting full disk images locally plus a cloud copy
Acronis True Image is the consumer backup product of Acronis, a Swiss company founded in Singapore and headquartered in Schaffhausen, Switzerland. Acronis's main business is selling cyber-protection services through more than 21,000 service providers to over 750,000 businesses; True Image is its retail line. The product combines full disk-image backup to local drives with optional cloud storage and security features, and each subscription protects up to five PCs or Macs plus an unlimited number of mobile devices. Three annual tiers are sold. Essentials does not include cloud storage at all, so it is a local backup tool rather than a cloud backup service. Advanced adds 50 GB, 250 GB or 500 GB of Acronis cloud storage, and Premium offers 1 TB up to 10 TB. The combination of local images and cloud copies follows the common recommendation to keep more than one backup copy, and it allows a full system restore to new hardware, which pure file-backup services do not offer. The purchasing page does not explain how prices change with the number of computers selected, so buyers should check the basket before paying.
Key features
- Full disk-image backup
- Cloud storage from 50 GB to 10 TB
- Up to five PCs or Macs per subscription
- Unlimited mobile devices
- Integrated security features
Pricing
Essentials: US$49.99/year (no cloud storage). Advanced: US$57.99/year with 50 GB, 250 GB or 500 GB cloud. Premium: US$124.99/year with 1 TB to 10 TB cloud. Plans cover 1, 3 or 5 computers; the page lists starting prices and does not state per-computer increments.

6
Backup app for Mac and Windows that writes to the user's own storage or Arq's cloud
Best for: Technical users who want to choose and control the storage destination
Arq is a backup application for macOS and Windows that separates the software from the storage. Arq 7 is sold as a perpetual licence that the buyer keeps, and it backs up to storage the user configures: many cloud providers, an SFTP server, an external drive or a NAS, including several destinations at once. Data is protected with end-to-end encryption so that, in the vendor's words, it is readable only by the owner. For users who do not want to manage storage, Arq Premium bundles the app for up to five computers with 1 TB of Arq-managed cloud storage and web access to backups. This model suits technically confident users who already pay for object storage, such as Backblaze B2, Wasabi or Amazon S3, or who want a local and an off-site copy from one tool. The trade-off is that storage charges, retention settings and the integrity of the target are the user's responsibility when Premium is not used. Arq offers a 30-day free trial, and the vendor listed version 7.51 for both platforms, released on 5 November 2026. Updates after the first year cost US$25 per computer per year.
Key features
- Back up to any of many cloud providers, SFTP, NAS or USB
- Multiple destinations at once
- End-to-end encryption
- Premium plan with managed cloud storage
- Web access to Premium backups
Pricing
Arq 7 licence: US$59.99 per computer, app only (one year of updates included; then US$25/year per computer). Arq Premium: US$69.99/year for 5 computers and 1 TB; additional storage US$0.00699/GB per month. 30-day free trial.

Client-side encrypted backup with unlimited devices on every plan
Best for: Privacy-focused users backing up several computers including Linux
SpiderOak One Backup is a backup and sync service from SpiderOak, which says it has been protecting data since 2007 and serves users in 77 countries. Its main distinguishing feature is client-side, no-knowledge encryption: files are encrypted on the device before upload, keys remain with the user, and the company states that it cannot read files, view metadata or access passwords. Every plan allows an unlimited number of devices across Windows, macOS and Linux, and plans are priced by capacity per user, from 150 GB to 5 TB. A 21-day free trial is available on every plan without payment details. The privacy model has practical consequences: because the provider cannot read the data, it cannot reset a lost password or recover files for the user, and server-side features such as content search or previews are limited. The vendor's privacy claims appear on its own page without links to independent audits or certifications, which buyers in regulated sectors may need to request directly. The service has moved to the spideroak.one domain; the former product address on spideroak.com redirects there.
Key features
- Client-side, no-knowledge encryption
- Unlimited devices on all plans
- Windows, macOS and Linux
- Backup plus sync
- 21-day trial without payment details
Pricing
Per user: 150 GB US$6/month or US$69/year; 400 GB US$11/month or US$115/year; 2 TB US$14/month or US$149/year; 5 TB US$29/month or US$320/year. 21-day free trial.

Swiss cloud storage with automatic backup and lifetime plans
Best for: Users who prefer a one-time payment and Swiss-based storage
pCloud is a cloud storage service operated by pCloud International AG, which cites Swiss privacy law in its marketing. It is primarily a storage and sync product rather than a dedicated backup service, but it includes automatic backup of a phone's photo gallery and of desktop folders, and a third-party backup feature for copying data from other services. pCloud is unusual in selling one-time lifetime plans: 500 GB, 2 TB and 10 TB tiers, plus a 3-in-1 bundle that includes pCloud Encryption (its client-side encrypted folder) and the pCloud Pass password manager. Family plans cover up to five users, and a separate business offering exists. Because pCloud is sync-oriented, deletions and changes propagate across devices unless recovered from its trash or file history, so it is weaker than dedicated backup services as protection against ransomware that encrypts a synced folder. Client-side encryption is not included in the standard plans; it is part of the bundle or sold separately. Prices on the pricing page are in euros and, when consulted in November 2026, a seasonal promotion was displayed beside the list prices.
Key features
- Lifetime storage plans
- Automatic phone gallery and desktop backup
- Third-party cloud backup import
- Optional client-side encrypted folder
- Family plans for up to five users
Pricing
Lifetime list prices: Premium 500 GB €279; Premium Plus 2 TB €709; Ultra 10 TB €2,799; 3in1 Bundle 3 TB with Encryption and Pass €1,517. Promotional prices shown in November 2026: €159, €379, €1,099 and €579 respectively. Annual prices, family and business prices were not displayed on the page consulted.

Synology's cloud backup for PCs with EU or North American data residency
Best for: Synology users and buyers needing EU data residency
Synology C2 Backup is the cloud backup service of Synology, the network-attached storage manufacturer, and sits within its C2 family of cloud services. It backs up Windows PCs to Synology's C2 servers, either selected folders or the entire device, and the entire-device method can include external drives when the option is enabled. Subscriptions come in three capacities, 500 GB, 1 TB and 2 TB, billed monthly or yearly, and customers choose data residency in Europe or North America. A 30-day free trial is available. The pricing page computes VAT from the billing address and showed no fixed prices when consulted, so this list does not state them. The service is most relevant to existing Synology customers who already use the company's management tools, and to European buyers who need data held in an EU region. Compared with unlimited services such as Backblaze, its capacities are small, and the 2 TB ceiling rules it out for large media libraries.
Key features
- Folder or entire-device PC backup
- External device backup option
- Europe or North America residency
- Monthly or yearly billing
- 30-day free trial
Pricing
Three plans: 500 GB, 1 TB and 2 TB, monthly or yearly. Prices are shown at checkout with VAT based on billing address and were not published on the page consulted; 30-day free trial.

SaaS backup on its own vendor-independent cloud, priced per seat
Best for: Organisations wanting SaaS backups outside the source vendor's cloud
Keepit is a backup service for software-as-a-service applications that runs on data centres it owns and operates rather than on a public cloud; the company states it uses no third-party subprocessors for data processing. It protects Microsoft 365, Microsoft Entra ID, Power Platform, Dynamics 365, Azure DevOps, Salesforce, Google Workspace, Zendesk, Confluence, Jira, Okta, Docusign, BambooHR, Miro, GitHub and monday.com, among others. Backups are kept as four copies in two separated data centres within the region the customer selects. Pricing is seat-based and includes unlimited hot storage with no fees for data ingress, egress, restores or transactions; the per-seat price falls as seat count rises, but no prices are published. Three editions are offered: Core Continuity with recovery for up to five years, Business Resilience with up to ten years and Microsoft 365 multi-geo support, and Enterprise Resilience with a dedicated customer experience manager. Keepit's site displays an ISO/IEC 27001 certification badge. The independence from Microsoft and Google infrastructure is the main argument for Keepit over native tools, since an outage or account compromise on the source platform does not reach the backup copy.

SaaS-delivered backup for endpoints, SaaS apps and data-centre workloads
Best for: Mid-sized and large IT teams consolidating SaaS, endpoint and server backup
Druva sells data protection delivered entirely as a cloud service, so customers do not deploy backup servers or storage. Its catalogue spans data-centre workloads (virtual machines, files, NAS and databases), public-cloud workloads, productivity suites (Microsoft 365, Google Workspace, endpoints and Microsoft Power Platform), identity systems (Entra ID, Active Directory and Okta), CRM (Salesforce and Microsoft Dynamics 365) and what it calls AI data, naming Microsoft 365 Copilot and Claude. Licensing options include individual workload tiers, a SaaS Universal License that covers all SaaS and identity workloads under a unified per-user licence with dynamic pooled storage, and an Essentials Pack for small and mid-sized businesses that adds VMware, Nutanix, Hyper-V, Proxmox, SQL, Oracle, Azure and AWS workloads. Druva says it is trusted by thousands of enterprises but does not publish prices; a free trial can be started online. Compared with Keepit, Druva covers on-premises servers and laptops as well as SaaS, which makes it a candidate for consolidating several backup tools; compared with CrashPlan, it is aimed at larger IT teams and has no self-serve price list.
Key features
- Fully SaaS-delivered, no backup infrastructure
- Microsoft 365, Google Workspace and endpoint backup
- Entra ID, Active Directory and Okta protection
- Salesforce and Dynamics 365 backup
- VMware, Hyper-V, Nutanix and Proxmox in Essentials Pack

Microsoft's native, pay-as-you-go backup for OneDrive, SharePoint and Exchange
Best for: Microsoft 365 tenants needing fast large-scale restores
Microsoft 365 Backup is Microsoft's own backup service for OneDrive, SharePoint and Exchange Online data, sold on a pay-as-you-go basis of US$0.15 per GiB per month for all protected data, with restores free of charge. Billing runs through an Azure subscription rather than per-user licences. Backups are created within the Microsoft 365 trust boundary and stored in append-only form, so existing backup content cannot be overwritten until it is permanently deleted. Microsoft quotes restore speeds of up to 1,000 average-sized OneDrive accounts or SharePoint sites at a median of 1 to 3 TiB per hour when express restore points are used. A backup policy can contain up to 100,000 items, and larger organisations are told to contact Microsoft. Microsoft also exposes the service to partner products that integrate it. The service's strength is restore speed for large-scale incidents such as ransomware across a tenant; its limitation is that the backup copy stays inside Microsoft's own environment, which some compliance frameworks and risk teams treat as insufficient separation, and it does not cover Teams chats, Entra ID or non-Microsoft applications according to the workloads listed.
Key features
- OneDrive, SharePoint and Exchange Online coverage
- US$0.15 per GiB per month, free restores
- Append-only backup storage
- 1–3 TiB per hour bulk restores
- Billing through Azure subscriptions
- Partner integration APIs
Pricing
Pay-as-you-go: US$0.15 per GiB per month for all protected data; restores are free; billed via an Azure subscription.
- Vendor

Strengths
- No per-user licence; pay only for protected data
- Very fast bulk restores
- Append-only storage resists tampering
- No separate vendor contract for Microsoft customers
Limitations
- Backups remain inside Microsoft's environment
- Covers only three Microsoft 365 workloads

O
Salesforce-native backup, archiving and seeding, now owned by Salesforce
Best for: Salesforce customers wanting first-party backup and archiving
Own Company is a data protection and data management vendor focused on SaaS platforms, especially Salesforce. Salesforce signed an agreement on 5 September 2024 to acquire Own for approximately US$1.9 billion in cash, net of the roughly 10% of shares it already held, and completed the acquisition on 18 November 2024. At announcement, Salesforce said Own was trusted by nearly 7,000 customers and had been a Salesforce AppExchange partner since 2012 and a Salesforce Ventures portfolio company. The Own Data Platform provides backup and recovery together with data archiving, sandbox seeding, security and analytics capabilities. For Salesforce customers, the acquisition makes Own a first-party option, which simplifies procurement and support. The same fact cuts the other way for buyers who want a backup held by a vendor independent of the source platform, the argument made by Keepit and others. Pricing is negotiated with Salesforce and was not published on any page consulted for this list, so it is listed as quote-based.
Key features
- Salesforce data and metadata backup and recovery
- Data archiving
- Sandbox seeding
- Data security and analytics tools

Frequently asked questions
What is the best cloud backup service?
No single service is best for every case. For one computer, Backblaze offers unlimited storage for US$99 a year with a free one-year version history. For many devices, IDrive and SpiderOak One pool storage across devices. Businesses protecting laptops often use CrashPlan, while Microsoft 365 data is better served by Microsoft 365 Backup, Keepit or Druva.
Is cloud backup the same as cloud storage?
No. Cloud storage such as Dropbox or Google Drive synchronises files, so a deletion or ransomware encryption on one device usually spreads to the cloud copy. A backup service keeps earlier versions and deleted files for a set retention period and runs automatically, which allows recovery to a point before the damage occurred.
How much does cloud backup cost?
Published prices in November 2026 range from free tiers (IDrive's 10 GB) to about US$70–125 a year for personal plans, such as SpiderOak One at US$69 for 150 GB, Backblaze at US$99 unlimited and Acronis True Image Premium at US$124.99. Business plans are often per user, for example CrashPlan at US$7.33 per user a month.
Do I need to back up Microsoft 365 or Google Workspace?
Microsoft and Google keep their services running and replicated, but deleted or overwritten items are only recoverable for limited periods. Dedicated backup keeps copies longer and allows restore after malicious deletion or ransomware. Microsoft now sells its own Microsoft 365 Backup at US$0.15 per GiB per month, and third parties such as Keepit store copies outside Microsoft's cloud.
Is cloud backup enough on its own?
Security agencies recommend more than one copy. CISA advises keeping offline, encrypted backups of critical data and testing restores regularly, because ransomware often targets reachable backups. Many users combine a local disk image, for example from Acronis True Image or Arq to an external drive, with an off-site cloud copy.
How long does a cloud restore take?
It depends on data volume and internet speed; restoring several terabytes over a home connection can take days. Some vendors offer alternatives: Backblaze ships an encrypted USB drive that is free if returned within 30 days, and IDrive Express sends physical storage. Microsoft quotes 1 to 3 TiB per hour for Microsoft 365 Backup express restores.
What does private-key or zero-knowledge encryption mean?
It means data is encrypted on the user's device with a key the provider does not hold, so the provider cannot read the backup. SpiderOak One works this way by default, and IDrive and Backblaze offer it as an option. The drawback is that a lost key or password makes the backup permanently unrecoverable.
