Since no one else has chimed in yet. I will give it a shot. I have not had to
manaully do anything with my tape drive in a while other than change tapes. I use
amanda to back up 4 machines on my network to a DLT drive.
I would first check to see if the drive can be talked to. A quick simple test, I
would do is use mt to see if it can talk to the drive.
The drive should be /dev/st0 or /dev/nst0 (no rewind) viewing /var/log/messages or
dmesg should indicate it was found.
Create a symlink to it from /dev/TAPE (this should be the default for most programs
that are tape aware including mt IIRC. Might be there already. If not:
ln -s /dev/st0 /dev/TAPE
try:
mt retension
This shoud take the tape all the way to the end and back. Not a bad idea for new
tapes anyway.
If that worked,(drive kicked of an ran for a while) then send a short file to the
device, or tar a directory or two and send it there. The thing that I had the most
trouble with as I first started dinking with tapes is treating the device as the
filename. Once I got that down I had few problems.
try something like : (its been a while but should be close)
cd /tmp
tar -cv ./* >/dev/TAPE
I suspect that tar -cvf /dev/TAPE ./*
would work as well
This creates a tarfile with the contents of /tmp and all subdirectories and sends it
to the tape.
to check it you can
mkdir /tmp/tapetest
cd /tmp/tapetest
tar -xv * < /dev/TAPE
Should create a tmp directory tree under the tapetest dir.
you can also simply cat a file to the device
cat myfile >/dev/TAPE
cat /dev/TAPE < myfile.too
There are lots of sites with better information. search on backup tape of something
similar in google
