Product Features

Everything you wanted in a backup app

True privacy and control

Arq encrypts your file data before it leaves your computer, so your files are never sent on the network in the clear. You choose the encryption password. We have no access to your files. All transmission over the network is through SSL/TLS.

Totally transparent

Your backups are stored in an open, documented format. We've published an open-source command-line utility so you can see for yourself your backups and directly restore your files from cloud storage. Other users have also contributed Arq-compatible utilities like arqinator.

Awesome Support

We're obsessive about getting solutions to customers' problems, so we strive to fix issues in Arq quickly. We often deliver patches within days or even hours of first report of a software problem. Email us at [email protected] and we'll get back to you promptly.

Native apps

Both Arq for Mac and Arq for Windows are native apps built for maximum device fidelity and maximum performance. No Java means no Java-related upgrade headaches or performance problems.


Arq does all it can to minimize uploads: Compression reduces upload sizes. Client-side de-duplication ensures Arq never uploads the same content twice. Rsync-style "rolling checksum" ensures only the changed parts of files are uploaded.

Cloud Choice

You can back up to your own Amazon Cloud Drive, Amazon Web Services, Google Cloud Storage, Google Drive, Dropbox, or OneDrive accounts, or your SFTP server or NAS. Use that extra space in your existing cloud account to store your encrypted backups.

Unlimited in every way

  • Arq backs up everything or just the files you choose.
  • Arq doesn't skip videos or ignore certain file types
  • Arq backs up files of any size -- 4GB, 40GB, it doesn't matter
  • Arq backs up your external drives
  • Arq backs up your network drives
  • Arq doesn't delete backups of your external drives just because you haven't plugged them in lately
  • Arq doesn't forcibly delete old backup records (unless you tell it to).
  • Arq restores your files onto any computer.

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
