Yes, look in the indices to see where the last level 0 is for the stuff you need to recover. Put that tape in the drive. Rewind the tape with mt & check it with an mt status to make sure its ONLINE and BOT. do: cd someplace where you have the tapes contents worth of scratchpad space to fill up with the below operations. do: dd if=/dev/nst0 bs=32768 count=1 It should spit out the tapes label block to your shells screen. do: dd if=/dev/nst0 bs=32768 count=1 It should spit out the instructions and syntax required to recover the first file on the tape do that do: dd if=/dev/nst0 bs=32768 count=1 It should spit out the instructions to read the next file do that repeat as required till you have read what you needed, or hit the tapes EOT. Put the next tape in and repeat until you are uptodate. Copy data back to original location. Yes, its time consuming, but it works, I've done it a couple of times now. You might need to change the device if your tape isn't on /dev/nst0, but make sure you are using a non-rewinding device as /dev/nst0 is. On linux, its a 99% probability that its /dev/nst0. If you feel really confident, you could cd to the directory that data came from in the first place, and just let tar overwrite whats there. But I sure wouldn't do it the first time I tried it, Murphy is alive and well you know. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
