What started out as a foray into experimenting with the newly released Samba 3, XFS, LVM and ACL's has panned out to be potentially of use beyond it's original requirements.
We, like everyone else, have daily backups. We also have people who delete work in progress, even though they might be saving every 5 minutes. What I describe at this web page is an experimental setup where there are snapshots taken every 30 minutes. Users can blow away folders and haul them back themselves. They can recover work they clobbered or deleted, assuming that they saved the file within the last 30 minutes. They can go back and grab a version 2 hours ago.
This may be of use to someone else, I can see it being useful to us. If nothing else the XFS/ACL/Samba should be of use. The snapshotting also has use with Unix/Linux users as well as the snapshotting could be applied to any filesystem. Indeed it's somewhat easier in the Unix/Linux world as the Samba layer just disappears.
It's also absolutely free ;) and transparent to the Windows users.
Enjoy & experiment.
