B2D Media Selection

Created: 30 Apr 2013 • Updated: 06 May 2013 | 4 comments
This issue has been solved. See solution.

We are currently running Backup Exec 2010 R3.

We have individual jobs for backing up Virtual Machines (on Hyper-V).

Job 1 Configuration: Backup Server 1   ->   to B2D Folder A   ->   Media Set 1
Job 2 Configuration: Backup Server 2   ->   to B2D Folder A   ->   Media Set 2

The media set has overwrite protection for 8 hours, so the media should be overwritten each night by the new Job.

Problem:

If Job 2 Fails and the files in Media Set 2 are not updated, then the next night Job 1 will overwrite the files on Media Set 2, which are now moved to Meida Set 1.
I now have to copies of Server 1 (in Media Set 1), but have lost my backup of Server 2 (Media Set 2 is empty).

I understand that it is reccomended to not have multiple B2D Folders, but cannot see how else to overcome this problem.

Any help would be greatly appreciated.

1) You should set a longer OPP so that your backup sets does not get overwritten so soon.

2) Are you using a device pool?  Otherwise, BE will not use the media in another B2D folder.

Thanks pkh,

1)  I did not want to increase the OPP, as I only wanted 1 copy of the back on file.
     It's just that I only want the same job to overwrite the media set each day, not another job.

2)  At the moment all jobs are pointing to a single B2D folder.
     I thought it was recommended to have only 1 B2D folder to reduce fragmentation.
     I am trying to use the media sets to group the backup files created.

Do you think I should change the configuration?

Thanks Again.

When you point to a single B2D folder, all the media in that folder is available to all your jobs that point to that folder.  Unless they are protected, then they can be overwritten by another job.  Either use another folder for your each of your jobs or lengthen the OPP so that when another job runs, the media is still protected.

As an aside, unless you are duplicating the backup sets to other medium, having a backup set that is only current for a day is not much of a protection.
