Backup Exec 12.5 Full tape and failed backups
Updated: 22 Nov 2011 | 4 comments
Hi all,
I'm running Backup Exec 12.5 on Windows 2008 Server 64bit and have a problem with backups failing.
We have a weekly tapes that backup on a Friday, the problem i'm having is that the backup starts but then runs out of avaliable space on the tape and stops and partitally ejects the tape and sits there waiting for me to install some new media. If I cancel the job and insert the tape again and restart the job it will complete. I'm guessing because at this point it knows the tape needs to be overwritten.
My question is, how do I prevent Backup Exec from partially ejecting the tape? and how do I then make it re-run the backup on that tape?
Many Thanks
Matt

What you are experiencing is
What you are experiencing is the normal BE behaviour when the tape is full. You need to put in a second tape for the job to complete. If you just re-insert the tape that was just ejected and your OPP is not long enough, the ejected tape would be overwritten and you would not have a full backup, i.e., you have overwritten the first part of the backup, thus it is incomplete.
If you want to squeeze everything onto one tape, you should enable compression if you have not already done so or get a tape and tape drive with a higher capacity.
If you want to use the full capacity of your tape, you should specify overwrite, and not append, for your job.
I realise this is normal and
I realise this is normal and it is expecting to continue the backup on another tape but what I would like it to do is not to eject the current tape and to start the backup from the start again on the full tape ie. Overwriting it.
If I stop the job, and reinsert the tape it ejected and start the job again, it works.. So I beleive I have the overwrite permissions correct.
Thanks in advance

As I said before, if it does
As I said before, if it does that, then you would have loose your backup because the first part of your backup would be overwritten. Have you tried to restore from one of the jobs that you have stop and restarted?
Post the OPP and AP of your media set that you tape belongs to and the what is your job properties set to, i.e. whether it is set to overwrite or set to append.
Loosing the first part of the
Loosing the first part of the backup is fine.
I want to scrap the backup that fails due to lack of space and on the same tape start a backup job again. I realise this will overwrite whatevers on the tape before but thats fine. I just want to prevent BE ejecting the tape and waiting for new media and instead, re-run the backup job on the same media.
Hope this makes it clear, I don't know how to explain it another way.
A little more information
We have tapes for the following, Monthly and Weekly.
On the Weekly tape we do a Differencial backup on a Wednesday and a Full backup on the Friday. So incase of failure I have full backup from the week before on one tape and a differential for half the week on another tape. I know this means there are a couple of days where we are not protected either side of the backup but thats what i've got to work with. I'm only onsite twice a week, so changing the tapes is a problem. I'm looking to do a backup to disk on a NAS drive to fill in some of the gaps.
Many Thanks
Matt
