"I honestly love this app" — Marco Arment

"@arqbackup I just switched from Arq 6 to Arq 7 and it’s great. Really nice work. Your tool makes backups a joy." — @reactorcontrol

"After 3 complete failures of Time Machine (to a Synology, APFS Disk Image, SMB) since I’m on Big Sur, I migrated this task to my beloved @arqbackup app and it works like a charm." — @benoitsan

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

Just upgraded to Arq Backup 7 by @arqbackup , and very happy with the new version! Everything is working smoothly. Highly recommend this backup solution for both Mac and Windows users.

@halfSpinDoctor 23 Feb 2021

Arq 7 is great - thanks for bringing back the native UI, @ArqBackup!

@stevex 21 Feb 2021

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

@flomotlik 8 Feb 2019

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!

@johnspurlock 16 Oct 2018

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.

Frequently Asked Questions

Licenses and Subscriptions

What is the difference between Arq 7 and Arq Premium?

Arq 7 is an app that you install on your Mac or Windows PC that backs up your files to whatever storage location you configure (see "Back up to your own cloud account" above). Arq Premium is a subscription that includes a license for Arq 7 on up to 5 computers plus a built-in cloud storage option that we manage for you. It includes web access to your backups. Additional GBs over the 1TB of storage are billed at $.0059/GB per month. Visit our Pricing FAQ for more details.

What updates are included with an Arq 7 license?

When you purchase an Arq 7 license, you keep the app you bought forever. You also receive one free year of app updates. After your first year of updates, you can subscribe to additional years of updates at $25 USD per year per computer. Or just purchase an "upgrade" of another year of updates whenever you feel so inclined. More details in our Arq 7 Pricing FAQ.

I purchased a "lifetime" license code for Arq 5 or Arq 4. Can I use it with Arq 7?

Yes. If you had Arq 5 installed when you installed Arq 7, Arq 7 will use the lifetime license information from Arq 5’s configuration files.

Arq 7 Backward Compatibility

Is Arq 7 backward-compatible with Arq 6, Arq 5, Arq 4, etc?

Yes. Arq 7 is completely backward-compatible with backup sets created by Arq 6, Arq 5, Arq 4, etc.

macOS Ventura login item

Why is there a login item in System Settings on macOS Ventura for "PhotoMinds LLC"?

That’s the ArqAgent LaunchDaemon. We’re trying to get Apple to change the name that appears in System Preferences.
