Hi,
I have inherited DPM 2012 server which has 2 protection groups which also uses SAN storage for short-term backups and tape for long-term. Also tape co-location is enabled for efficiency.
The problem I have found is that on the weekly tape management reports the tapes that the server requests are not always sufficient to backup all the protection groups so I have started to fill the entire tape library (48 tapes). The other problem is that sometimes a number of jobs fail and when I check the errors it reads:
Failed to perform the operation since the tape free tape is not available in Tape Library HXX library (x64 based) (ID 24050)
The job has some data transferred for example 550GB so I instantly assume that the tape got filled and the job needed another tape. Other failed tape backups show 0MB transferred data so I imagine no tape was available. From the errors I am unable to tell which tape the job wanted as per the long term retention policies. I am after some advise on how best to tackle these problems as I believe the server configuration needs some TLC
Another not is there way or online reference I can use to built my own backup reports via powershell as the builtin ones are pretty poor
