Arq

Backup app for Mac and Windows that writes to the user's own storage or Arq's cloud

Overview

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[15]. Data is protected with end-to-end encryption so that, in the vendor’s words, it is readable only by the owner[15]. 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[15][16]. 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[15]. Updates after the first year cost US$25 per computer per year[15].
