[Gluster-users] Turning GlusterFS into something else (was Re: how well will this work)

[Fred van Zwieten]

An alternative to undelete is snapshotting. This also gives protection
against "logical data corruption" like virus infections or data changes
because of bugs or simply human failure. I am a huge proponent of solving
as much as possible problems with a single solution. And, afaik,
snapshotting is being worked on or is at least on the roadmap.

Cheers,
Fred
