Arq is an online backup app from Haystack Software. Unlike many online backup systems, Arq doesn’t provide cloud-based storage. Instead, it works as a front end to existing storage systems.

Arq works seamlessly with Google Drive, AWS (Amazon Web Services), SFTP (Secure File Transfer Protocol) servers, Greenqloud, DreamObjects, or any S3-compatible storage system. One of the really nice aspects of Arq is that by allowing you to decide which cloud storage system you want to use, you can choose the system with the feature sets that will best meet your needs. A good example of this is combining Arq with Amazon Glacier, an S3-based service that has exceptionally low storage costs, as low as $0.01 per GB/month.
