How to set device priority in backup exec 11d?

Posted on 2010-09-19
Last Modified: 2013-12-01

I am running back up exec 11d in windows server 2003 R2 with 8 jobs, 4 incremental and 4 Full jobs. I used back up to disk folder but I am now also using Dell Tape Library TL2000. I want to backup to tape but I still want to leave the backup to disk just in case if tape does not work, back up to disk can take over.

The problem I am having right now is, all the back up jobs are backing up to disk and not to the tape. It was backing up to the tape fine before I recently created 2 new jobs. How can I set the priority to tape first and then to b2d? It backs up to tape only when I change the target device to tape but if I leave it to "All Devices" it backs up to b2d.

Even after I change the priority to devices listed in my device pools i.e. 1 to IBM1 (tape) and 10 to Back-up-to Disk, it gets defaulted back to priority 10.

Any help on this is greatly appreciated.

I make my backup to disk first and after that a duplicate job to tape. The duplicate follows the backup to disk so it starts always after. Backup to disk never failes so you always have a backup when the tapes failes. You can alsway retry to tape if needed.

Thanks Williamvanerp, but can i do it the other way around? Why am I not able to set the priority?? Is it a bug that Symantec never fixed??

Do you have also a IBM3 where you can set priority on? IBM1 and IBM2 as are the tape units (in the TL2000) and IBM3 the TL2000. When making a backup, the device to use is the IBM3.

Under Robotic Libraries, I have IBM2 and IBM2 has IBM1 and Slots. I do not have IBM3. Device Pools has ALL Devices and it has Backup-to-Disk Folder(Shared Storage) and IBM1(Shared Storage).

All jobs under Destination (Device and Media), targeted Device is chosen as "All Devices". If I drop down Device, It has the following:
Device Pool: All Devices (server Name)
Shared Storage: Backup-to-Disk Folder 2, IBM1 and IBM2

Then you have one tape unit in the TL2000.

You maybe want to make a duplicate job after the backup to tape. First you make a job to tape, use the IBM2 as target device. Then you make a duplicate job, following the first job to tape, and select the backup to disk folder as target. In the duplicate job wizard you can point to the first backup.

You can also use this article:

Only backdraft is, if the first backup fails, the second will either because it uses the backup set it made.
My experiance is when a job fails, it has to do with one of the services and not with the tape or disks, so either way the job would have failed both ways.

With the device priority, to keep in mind is that overwrite and append periods for media take precedence over device priority. So if your Backup to disk folder has an older overwrite periode, it might take that one first. In a device pool, Backup Exec selects the oldest recyclable media in all of the devices in the device pool to use first. If more than one media that meets the requirements is found, Backup Exec then searches the devices in a device pool according to device priority and uses the oldest recyclable media in the device that has the highest priority. Maybe this gives a clue why it didn't work for you.

Thanks very much for the info. Is there anyway I can change the overwrite period  on the back up to disk folder so that I can have tape take precedence over the b2d??

Do you know about media sets? You will have to create a media set of the backup to disk. Then you have to set the overwrite periode on the media set. I use different media sets for my backup to disk and for my tapes.

I see that I use the same Media Sets for both Tape and B2D. I also notice Overwrite Protected Until for one of the Media Labels for tape has 9/23/2010 11:41:20 PM where as two of the media labels for B2D has Overwrite Protected Until 9/23/2010 4:28:15 PM and 9/23/2010 3:54:10 PM. All of these have Appendable Until  "Infinite-Allow Append"

Are you advising me to create a new media set for B2D? What will I do to those media labels which I already have on my existing Media Sets for B2D??
