I always thought that having a backup kept your hard drive from
crashing...  Kinda like having insurance on your car prevents accidents.
The one time I didn't get the CDW on a rental car, a bus ran into me (or,
actually, the rearview mirror got ripped off the car by a bus, but the
car rental company wanted $3,000 anyway...). So, I do nightly backups on
EVERYTHING!
        Now for a question... With Windoze machines, I've been able to take a
backup tape and restore it to a new harddrive and pick up where I left
off. This doesn't seem to work with Linux, since it seems to save a lot
of the machine's state at various locations on the hard drive. I tried
doing a reinstall of RH7.1, then copying back everything (that had been
tarred on tape). It really messed the machine up. I ended up having to
reinstall RH again, copying various config files I could identify,
reinstalling several aps (perl libraries, PHP4, etc.). I was able to just
copy the /home user files back. Copying back the password and shadow
password file seems to have restored user accounts.
        BUT, it seems that there SHOULD be a way to just get the machine back to
where it was, directly from tape. No reinstalls or anything. Can any
linux experts tell me how? It it's easy to do a restore, I'm sure I'll
never get another crash...
