Trying to adapt the knowledge to a tape library...
/sbin/dump -0 -v -z2 -f /dev/nst0 /var/log
/sbin/dump -0u -v -z2 -f /dev/nst0 /home
I have a cron job that dumps the results to /var/log/dump.log, and a
review of the log file claims all went well. Now for the restore...
I just tried playing with different options of restore, but could not
successfully restore anything. I ensured I was in a scratch area so as
to hopefully not overwrite current files.
What is the proper procedure for dumping and restoring now? Should I be
dumping to /dev/nst0/dump? What restore commands would I use to
recall a file?
I'd like to keep things as simple as possible - people have suggested
legato and amanda, but for now, I would think/hope dump and restore
would work.
First you need to determine if your problem is with dump or the tape
drive. Dump tends to be unhappy if the filesystem changes during the
run, so you might be better off using tar. Also, some tape drives are
picky about the block size used in writing and reading. You can use the
mt command to check/set the block size for the tape, and both dump and
tar have block size options that you can set to match.
