Hello Everybody,
On one of our servers were DPM in installed we receive the following errors while synchronizing recovery points for the First & Second storage group.
Every 15 minutes we do a synchronization, and every 15 minutes only the First & Second storage group errors when trying create the recovery points.
The exchange 2007 server is part of an Windows 2008 SBS server which is virtualized with Hyper-V.
In DPM 2010 we receive the following error when start creating recovery points:
Type: Recovery point

Description: 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.

I discovered that when I run a full backup, the First & Second Storage Group are running and succeed. When I do an Incremental Backup it fails.
If I do a; vssadmin list writers is see that the Exchange Writer is stable, but has a retryable error, state 7 failed.
Could anyone help me with this problem!
Thanks in advance!
