Some thoughts on enhancing cpio(1)

[Dave Dykstra]

[--]

Your idea for incremental backups, i.e. saving the directory contents and
removing the files which have disappeared, is good except for the case
where files are moved without changing their modification time.  Then
the files will not show up on the incremental backup but the file in the
former directory will be removed.

For a while we were losing our filesystems on a regular basis and we
found that incremental backups are basically useless; we do complete
backups every night now.
