I'd have to agree with this. Once you get past the sticker shock, the NetApp appliances are awesome. I found them to be fast and reliable, and the snapshot feature is a lifesaver. At any point in the filesystem, you can access a read-only ".snapshot" directory to recover older files. If you delete a file, or overwrite it, there's a copy in .snapshot/hour0/ to recover it from. If I recall correctly, the system retains 7 hourly and 7 nightly xnapshots by default. So you can always recover a file to its previous state from 1 hour ago, 2 hours, etc, and 1 day ago, 2 days ago, etc. The snapshots are actually pointing at the same inodes that the main file used; if a file hasn't been changed for at least a week, then all the snapshots are sharing the same inodes for that file. -- John Abreau / Executive Director, Boston Linux & Unix ICQ 28611923 / AIM abreauj / YAHOO abreauj Email [EMAIL PROTECTED] / WWW http://www.abreau.net / PGP-Key-ID 0xD5C7B5D9 PGP-Key-Fingerprint 72 FB 39 4F 3C 3B D6 5B E0 C8 5A 6E F1 2C BE 99 Some people say, "The enemy of my enemy is my friend."
