Compared to an actual defrag, this operation is
risky.  A power interruption could disrupt the process
at an unpredictable state.  If performed as an incremental
backup (multiple prior savepoints) and restore it could be effective,
though it would be disruptive to file timestamps and
filesystem flags.
