Apple Thoughts: Arq Online Backup for Mac Users

"There's yet another contender if you're looking for an online backup solution. Haystack Software has released Arq, a backup application that uses Amazon's Simple Storage Service (S3). Arq offers encrypted backups, flexible scheduling, and the ability to select and exclude files as you see fit."

Using Amazon's Simple Storage Service (or S3), Arq from Haystack Software offers a convenient way to ensure that your data is backed-up - and more importantly, can be recovered. While Time Machine offers a good, reliable local backup option, Arq is designed to also be a complementary 'disaster recovery' restore solution. Data is backed-up and restored via simple drag-and-drop operations. Multiple versions are stored to allow 'point-in-time' restores, and backups can be encrypted. An Amazon S3 account is required (with somewhat complicated tiered pricing) for storage, and Arq costs $29 for a single-copy, or $49 for a five-user family pack.
