SCO tape backups won't restore in Ubuntu Linux environment
Hello folks. I have the following problem:
I'm trying to create a tape backup of a list of files on a 10 year old server, running SCO Openserver 5.0.5 (the tape drive is a Seagate STD224000N, connected as a SCSI drive).
I then want to restore the contents of this tape onto a new server running Ubuntu Server 11.04 (the tape drive is a Quantum (Seagate) CD72LWH-SST, connected as SCSI).
The tape I'm using is a DDS3 tape (brand new) as it is the only tape which will work in both drives.
So I'm using tar to send some stuff to the tape on the old server, using this command to do so:
It seems happy to do this, and if I list what I just did on the tape using 'tar tvf /dev/rStp0', it shows me a list of the files.
So now I insert the tape into the new server, and I try to restore the tape's contents to the new drive with the command:
Doing so results in the following errors:
If I try typing sudo mt -f /dev/st0 status I get the following:
Also, not sure if this helps or means anything but if I type 'dmesg', some messages
seemingly related to sense errors appear towards the end of the file:
I've tried cpio as well, with the same results, whereby it seems to work fine
and list fine on the old server, but encounters read errors on the new server.
I'd be tempted to blame the tape, but it is brand new, and also that DDS2's
from the old server (which work fine on the old server) have similar input/output/'sense key' errors in a completely different server.
Apologies if this is seems rambling, I'm pretty much at a loss at where to go from here!
I read something about setting the
block size to something sensible, but I must admit I'm not great with tape-related stuff
and I couldn't figure it out. If anyone has any pointers, it would be great!
For those with backup tapes (and I just bought and installed a Seagate one for my FreeBSD box) I want to know how to get the most out of each tape by placing multiple backups on each tape (potentially 20GB). Please correct me if I'm wrong:
First, retension the tape:
# mt retension
next, turn... (3 Replies)
Currently am running the backup command for AIX 5L and see that the tape is rewinding after the completion of the back.
backup -0 -u -f /dev/rmt0 / >> $file 2>&1
What can I do to stop allow the backup to rew after the completion of this job? Any thoughts?
Thanks again. (2 Replies)

Hi, I am currently looking at how we can optimize and speed up our backups here. I am just a beginner operator and our system admin hardly knows anything (long term interim).
There is this particular TAR backup of DB backups that for a 10.5Gb amount of files, it takes 5 hours to do the backup on... (6 Replies)
It may seam a bit odd that I ask this question.
After you have done your backups to tapes, do you verify the content of the tapes ?
- never
- sometimes
- always
The reason I am asking is that here in the office, all the backup procedures include verifying the content of the tapes (no... (5 Replies)

Hello,
I need to be able to encrypt LTO tapes that our AIX writes to for backups.
We have a tape library (IBM TS3100) that our AIX host uses to write to LTO6 tapes. We then take those tapes off-site and restore to another AIX system using a 3580-H6S LTO6 tape drive - this is a very simple... (3 Replies)
