Linux Offsite Backup

Performing data backup and recovery in a Linux environment poses some unique challenges. Some of the biggest hurdles people run into with Linux backup have to do with compatibility. For example, people buy an elaborate tape library, and there are no Linux drivers available to go with it. Also when someone chooses an agent-based backup software product, and they are backing up a heterogeneous environment, no such agents are available for the operating systems they are trying to back up. Are there specific tools available for Linux backup? Do the major data backup software vendors offer Linux compatible products? Most data backup software vendor supports Linux to at least some degree. What about data deduplication? Are there products available that perform deduplication in a Linux environment? There are, but data deduplication is performed by most vendors as byte-level backups. But in the Linux environment, is data deduplication at the file-level. The following is a selection of Linux backup solutions:
