Re: [K12OSN] Tape backup



>From what I know, you will not see the tape drive listed under fstab. 
Try running "mt -f /dev/st0 status" and see what it says. It took me a
while to get my backups running (custom shell script around good ole
dump)!  Your best friend will probably be "man mt"... I have played
around with it a little bit (rewinding, ejecting, etc)... so  a good
test for you would probably be "mt -f /dev/st0 eject" to see if the tape
ejects... or at least goes "not in use" for you to remove the tape...
which is what my drive does.

It being on /dev/st does sound strange... it probably is /dev/st0 and
also /dev/nst0 (they refer to the same tape device, it just is when you
use /dev/st0, it will rewind the tape after every operation and
/dev/nst0 will not... usefully if you are using 2 dumps on a tape and
don't want the 2nd dump to rewind the tape and overwrite the first!)  I
sym-linked /dev/tape to /dev/nst0 (no rewind operations... I rewind
manually/when I need to).

There was a good explanation on the internet that showed how file
positions and EOF markers are used, but I can't find it... oh well.
