Good day to all.
Last month we set up monthly backup of some folders from file server (physical server, OS Windows 2012 Standard) through System Center DPM 2012 R2 (physical server, OS Windows 2012 Standard) to Azure Cloud Backup. Size of protected data: approx 1,6-1,8 Tb.
First backup (1 september) was successful.
Second backup (1 october) failing - job starting, running for ~3 minutes and completes with critical error:
Creation of online recovery points for E:\ on FILE-01.domain.local have failed. The last online recovery point creation failed for
the following reason: (ID: 3188)
An unexpected error occurred during the operation. (ID: 32505)
Read KB article https://support.microsoft.com/en-us/kb/3041338
Error 3188 can occur if DPMWriter service isn't running - but this service running OK (all local backups work just fine)
Error 32505 not listed in KB article (!)
Updated DPM from UR6 to UR7, and Azure Agent to last version (2.0.8719.0) - problem not resolved.
Checked recovery from first onlne recovery point - successful (so, Azure Vault is accessible).
