Is this a reference to snapshots? You can use ZFS for those. The kernel modules are only available in the form of 9999 ebuilds right now, but they your data should be safe unless you go out of your way to break things (e.g. putting the ZIL/SLOG on a tmpfs). Alternatively, there is XFS, which I believe also supports snapshots.
