The desigers of the Network Appliances WAFL file system built an
intelligent file system for human (i.e. non-infallable) people. With
it you can efficiently save snapshots of your directories on-line at
fixed points in time as far back as you'd like (modulo disk space, but
that's cheap these days). These snapshots can be mounted as file
systems so they're as easy to use as the current file system itself.
Typically a cron job is use to maintain snapshots from the last hour in
fifteen minute increments, the last day in one hour increments, the
last week in one day increments, etc. They fix the most common cases
of files that are accidently deleted. It'd be cool if Linux offered
this feature.
