Anyway, I have a ZFS storage unit here and this is my first exposure to it so I don't really know about any of this ZFS magic that I often hear about. I'm sure I could google and find some reading on the matter but am wondering if anyone has some recommended reading that is concise and to the point, and will give me a good intro. -- ?Don't eat anything you've ever seen advertised on TV? - Michael Pollan, author of "In Defense of Food"

The ones likely to be important for the filesystems holding backup archives are: compression block-level de-dup snapshots incremental snapshot send/receive easy-to-expand combined volume/raid management Backuppc does compression and de-dups at the file level with hardlinks so you get some of the missing features anyway, but it's not quite the same. -- Les Mikesell lesmikesell at gmail.com
