In this case I was trying to backup P2V converted VM using DPM 2012 SP1. The VM was hosted on Hyper-V 2012 cluster. DPM Replica Creation Job was failing with following description:
The VM had Windows Server 2003 SP2 operating system installed. I've decided to check the VSS writers, and the vssadmin has returned empty list of VSS writers available on the VM:
According from following Microsoft article http://support.microsoft.com/kb/940184/en-us , I've re-registered the following dlls:
cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 ole32.dll
regsvr32 oleaut32.dll
regsvr32 /i eventcls.dll
regsvr32 vss_ps.dll
vssvc /register
regsvr32 /i swprv.dll
regsvr32 es.dll
regsvr32 stdprov.dll
regsvr32 vssui.dll
regsvr32 msxml.dll
regsvr32 msxml3.dll
regsvr32 msxml4.dll
Now, running the vssadmin list writers again, has successfully listed all the available VSS writers. I was hoping that DPM will successfully finish Replica Creation Job, but I was wrong. VM was having ISA Server 2006 installed with local MSDE. Someone has changed ISA Logging destination from Database into flat files, and to free some space on disk deleted the mdfs and ldfs files from logging directory. Now, VSS was failing with error event id 6013 with following message:
Now I was looking for a way to dismount those old databases with deleted mdf and ldf files. Thankfully, Microsoft has publish a vbscript for dismounting old databases from MSDE, and here is the link from the source of the script http://technet.microsoft.com/en-us/library/cc302448.aspx .
After running the script, the old databases were dismounted, and finally I was able to backup the VM using DPM 2012.
DPM encountered a retryable VSS error. (ID 30112 Details: VssError:The writer experienced a transient error. If the backup process is retried, the error may not reoccur. (0x800423F3))
