Netapp implemented this perfectly with the snapshots feature of their
WAFL filesystem.  In every directory there is a .snapshots
subdirectory containing monthly, weekly, and hourly snapshots of the
parent directory.  If you hose your system recovery is as simple as
"cp -pr .snapshots/hourly.1/* .".

Unfortunately it's patented so Linux can't do the same...
