I'm considering setting up a live, 24-hour backup on my main server.
Basically my idea is to drop another HD in the system and mount it rw for root,
and ro for users. Essentially this drive would be a mirror of the users drive,
and each user will have a symlink from their $HOME back to this backup drive,
right into their folder:
$HOME/user1/.archive -> /var/backup/user1/
$HOME/user2/.archive -> /var/backup/user2/
$HOME/user3/.archive -> /var/backup/user3/
etc.
Every night I will do a mirror of the user directories, removing files they
have deleted from their home directory as well. I don't want to have a
constant backup of *everything*, just of what's current in their folder (so if
they deleted a file, it will be deleted that night from their backup as well,
and the only other backup would be what's on tape.) If they accidentally
deleted a file during those 24 hours period, they can copy it back from their
.archive folder before the backup runs that night again.
My whole take on this is to cut down on users that delete stuff then scream
bloody HELP through email asking for that stuff to be pulled back from tape. I
might even consider holding data for 48 hours instead of 24, but that depends
on how much data there is of course.
Does anyone see problems with this setup? Is there anything I should keep
in mind, or any caveats I'm not seeing here. Does anyone have any suggestions
on what to use, or how to make this easier, etc., etc.

W | I haven't lost my mind; it's backed up on tape somewhere.
