Dave Henderson (try pads!dmh) has a filesystem backup scheme that is invoked from cron. I put up a simpler system on spastic and sps. They use a shell script to log off any users left on with kill -1 commands. Then they unmount filesystem(s), run 'fsck', then 'dd' to unused disk filesystem slots. Dave's scheme does a full pack-to-pack copy on machines with multiple disk drives. The script finally remounts filesystem(s). When Dave gets to work, he swaps disk packs (that means going single-user a few minutes). We do not backup the entire disk, so we can 'volcopy' the disk to tape during the working day. This may not be as nice as using /etc/dump, but it does work. George T., spastic!grt and others
