Duplicating multiple B2D backups
I hope someone can help me here. I've searched the darkest corners of google for a solution but I can't find it.
Because a regular backup to tape took way too long I've been asked to get that backup time a little shorter..
A backup to disk duplicated to tape didn't really help, it's just too much data and too much small files.
So I thought, multiple backups to disk simultaniously, and then these can be duplicated to tape outside of the initial backupwindow because that doesn't affect the rest of the environment.
the backup to disks goes a a lot faster now!
I've spit the original selectionlist into 4 seperate selectionlists.
I created a policy with a daily full backup to disk job and a duplication to tape job.
Linked that policy to the 4 selections, so I now have 8 jobs (4backup and 4duplicate)
The backup goes great!
4 backup to disks simultaniously speeds up the backup a lot!
But the duplication fails..
"The job failed with the following error: The requested source duplicate could not be found. Perhaps the media containing the source backup sets was previously deleted"
But the media exists! The data also exists!
I can perfectly restore files from the B2D backup.. from all 4!
I can't find the error and it's killing me! I'm no backup guru but all the stories I read tell me that my setup shoudl work.
The most common error is trying to duplicate without using policies, but I AM using policies so that is not the issue here..
Another link I found said something about the combination with the end of the month but that's no issue here either..
It's a daily full backup... there's no other backup schedule that could interfere.....
Could someone please give me some explaination of why my duplication to tape isn't working?
Scheduled or manual doesn't matter.. it just looks like it looses it's connection with it's backup to disk and tries to backup something that doesn't exist anymore. But why?
The backup Exec version is 12.0 SP1
