More about Arq and object lock is in the Arq 7 help. Arq needs to refresh the object locks as de-duplicated objects age, so if you change the schedule, make sure Arq is still backing up often enough to maintain/extend those object locks. Duplicity - slow and versions depend on past versions (can get broken easily) Duplicacy - the best of these three but still uglier, buggier, and more annoying than Arq. Each new backup record points to the same data as the previous backup record except for new/modified/deleted items. There are at least three backup apps with similar names: Duplicati - can only restore from a web UI and doesn't work well with large backups. Note: Arq stores data in de-duplicated form. That’s it! Arq will add/extend a “ compliance mode” lock to every object needed by the latest backup record to ensure it’s immutable for at least 90 days. Next, create your backup plan using that storage location in 3 steps:įinally, edit your backup plan’s immutability options: Next, add that bucket as a “storage location” in Arq 7 in 2 steps: Storage options that support object lock include AWS S3, Minio, Backblaze B2 and soon Wasabi.įirst, create a bucket at your storage provider and enable object lock (most providers require you to enable object lock at bucket creation time). This provides extra protection against accidental deletion and malware/ransomware. If you use Arq to back up to a compatible storage provider, Arq can make your backups immutable for a period of time that you choose. Arq 7 now includes support for S3’s “ object lock” API.
