Manual?

Try scripting. For me, that's a tar command involving /home, /etc, and
about one or two other files, with a few excludes, like /home/shared/video.

A lot of the people I know keep stuff on their DVDs, like movies and
music, so they can carry them around. And the rest of it is the 50 megs.

Streamload is quick and transparent for me. I put files on the
fileserver, it tars them up and uploads them via Streamload's perl client.

Not totally unrelated. COW has been discussed. I don't remember if the
low-level stuff was done, but the main complaint was a lack of a copy
system call.

And RAID is an argument for Reiser4's attitude that it's not the job of
the FS to be corruption-proof.

Still, it's far easier to avoid deleting stuff than to avoid disk
failure. First priority is to get the stuff OFF the machine.
