File backup without compromise.

We believe you shouldn't have to give up your privacy or control to get the benefits of the cloud.

Arq backs up your files to a cloud account you already have, or attached disk, or both, with strong, end-to-end encryption so your data are only readable by you.

No limits.

No vendor lock-in.

Go back in time.

Arq uses filesystem snapshot technology to make perfect, point-in-time backups of your files, even if your files are changing during the backup process.

Arq keeps multiple backups of your files — a backup history. So if you discover a file was corrupted, or accidentally deleted, or encrypted by a ransomware attack, you can go back and get the old version.

Back up to
your own
cloud account.

Arq Backup integrates with many different cloud providers. So if you have a cloud account with some extra space available, use it for encrypted, versioned backups of your important files.

You can also back up to an SFTP server or an external drive or a NAS.

Or back up to all of the above! Arq can back up to multiple destinations.

We also offer Arq Premium: the same great app for up to 5 computers plus integrated cloud storage in one package.

Lots and
lots of
features.

Efficient — compression, de-duplication, block-level incremental backup

Unlimited backup — backs up any file size, file type, external drive, network share

Versioned file backup — keeps multiple versions of your files; if you discover a file is corrupted, go back in time to get an earlier version

Unlimited retention — keeps backups of your USB drives even if you never reconnect them

Ransomware protection — point-in-time recovery of files

Restore right from the app — no downloading of zip files

Configurable to your needs:

  • back up hourly or daily
  • prevent backup on specific Wi-Fi networks and/or network interfaces
  • prevent backup while on battery power
  • limit bandwidth usage
  • limit retention to reduce storage usage
  • custom file/folder exclusion rules
  • include network shares

Awesome customer service

Stable, self-funded, owner-operated, profitable company since 2009

Open and
transparent.

Arq stores your encrypted backups in a format that's open and documented.

Knowing where your backups are and being able to see the data directly brings peace of mind.

Happy customers!

Reading the changelog of @arqbackup for Arq 7 "We worked with Apple to get native APFS snapshot support into Arq 7." makes me feel jealous. My loved OSS backup solution @resticbackup does not. I'd love to know how Arq pulled this off! This is *critical* for a backup solution IMHO

For my more tech minded pals, Arq 7 just launched. A great backup client that allows you to backup your machine to many different cloud storage providers. I use AWS S3. No affiliation, just love the app @arqbackup https://arqbackup.com

Successfully used @arqbackup to restore over 1TB of data from @backblaze B2 storage. I’ve used Arq to restore a file or two here and there, but this is the first time restoring from a complete disk failure. Great to see it worked so well!

Thanks to @arqbackup for their help getting my backups working again after a Windows update messed up multiple installed applications, even though the root problem wasn't to do with Arq.
