Well, I've managed to read just enough varying documentation to confuse myself on the issue of tape backups. I have a SCSI drive that supports QIC-3080XLF tapes (2 gigabytes native-uncompressed). I'm a little at a loss as to how to proceed. I've looked at ftape, zftape, the ftape settings under the kernel, but they all seem to reference the older QIC-80 style of floppy tape drive. Anyone have SCSI tape drives and back up to/restore from them regularly that could give me a pointer to where I should start?

Well, there are the /dev/nrmt0 and /dev/mt0 devices root@marvin:/usr/share/sounds/wav > ls /dev/*mt* -l lrwxrwxrwx 1 root root 4 Apr 5 20:01 /dev/nrmt0 -> nst0 lrwxrwxrwx 1 root root 3 Apr 5 20:01 /dev/rmt0 -> st0 as we see, they are symlinks. I can access my tape with "tar cfv /dem/rmt0 [directory]" Juergen -- =========================================== __ _ Juergen Braukmann juergen.braukmann@gmx.de| -o)/ / (_)__ __ ____ __ Tel: 0201-743648 dk4jb@db0qs.#nrw.deu.eu | /\\ /__/ / _ \/ // /\ \/ / ===========================================_\_v __/_/_//_/\_,_/ /_/\_\ -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
I've SCSI streamers that use DDS and DDS2 tapes. I don't use them regularly but I've been trying to learn how to make quick backups. To backup a directory use this command: tar cvf /dev/st0 /path this will not compress the files. If you want compression use the z option; it appears as if you will have problems reading the tape later, though. See messages posted here over the weekend, I have not tried it. As for the devices, /dev/st0 is the first scsi rewinding tape drive. That's the one to use if you want to place only one tar file in the tape. There is the /dev/nst0, the non rewinding one, this device driver will not rewind the tape after your tar command. It's used to put more than one tar file in the tape. You will need to use the "mt" tool along with tar, see the man page. For information on how to put more than one tar file in a tape, take a look at the FTAPE HOW-TO, there is a section in there as to how to proceed: http://www.linuxdoc.org/HOWTO/Ftape-HOWTO-7.html You may need to replace /dev/ftape with /dev/st0 or /dev/nst0 in the examples, but all of them apply for scsi tapes drives. -- Rafael Herrera P.S. In 7.4 in the above link, shouldn't the command be 'mt -f /dev/n???? eod'? -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
