As the other poster mentioned, ZFS snapshots is the way to go.

If you don't have these stored on ZFS filesystems, then check out
rsnapshot as an alternative:

    http://rsnapshot.org/

It's available in ports. You can do ZFS-style
hourly/daily/weekly/monthly snapshots. It uses hard links to save space,
so the overhead is not too high.
