"more reliable and easier to use than CrashPlan" MacWorld review

Go back in time

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

Back up external hard drives, NAS files, whatever you want. Arq has no limits.

The best backup software for Mac is now available for Windows users too.

Open and transparent

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

You control the backup data. Use Arq to backup to

There's even an open-source restore tool, so you can decrypt your backup data without the Arq app if you want to.

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

I'm a huge fan of Arq. It's reliable, easy to use, inexpensive, and keeps getting better. I highly recommend it.
