Bacula could be considered the premier upcoming backup application. Currently, it boasts clients working on Linux, FreeBSD, and Windows. It uses a MySQL backend. Configuration is very modular and easy to understand. From my current understanding, it's been used in a wide strata of applications; from home backup solutions to medium/large sized businesses. It's strength lies in it's ability to work with both Linux and FreeBSD systems connected to a single tape drive or autochanger. It also has no problem using a NAS/SAN or anything that can be mounted as a file system (writable) on UNIX. My personal experience with it has been very good and I use it for both home and corporate backups without a problem. The MySQL backend (like dump levels) makes it very handy too. View the website. The creator and user base have been very helpful in contributing good documentation.
