8/7/2006 5:21:52 PM    Missing shadows, Consistency failure
I'm having problems with 3 of my 4 protected servers. I've got KB910330 and 
 
KB911169 installed on my DPM. 1.3TB of 1.8TB storage pool is unassigned. 
 
Here are my problems: 
 
1) Exchange server runs a scheduled local NTbackup of store and has just the 
 
folder with this daily BKF output protected. After running a week, I only 
 
have a single recovery file on DPM. The previous files go missing every 
 
night without an error or complaint. Sometimes there are three available, 
 
sometimes none. 
 
2) SQL1 server runs a daily scheduled local backup of a database and local 
 
data files (Autocad Vault) and just the folder with this result is 
 
protected. Again, only a single recovery is available today. Sometimes more, 
 
sometimes none. No errors, no data. 
 
3) SQL4 server runs daily scheduled backup job along with 8 logfile backups 
 
for a total of 7 days of rolling backups available in the protected folder. 
 
Today I've got 3 days of files, but should have a week. Also I get errors: 
 
Event Type: Error 
 
Event Source: DPM-EM 
 
Event Category: None 
 
Event ID: 1 
 
Date:  8/7/2006 
 
Time:  9:00:17 AM 
 
User:  N/A 
 
Computer: MSDPM 
 
Description: 
 
The replica of C:\ on SQL4 is inconsistent with the protected data source. 
 
All protection activities for data source will fail until the replica is 
 
synchronized with consistency check. (ID: 3106) 
 
The DPM File Agent is no longer tracking changes on C:\ on SQL4. (ID: 107) 
 
DPM PS ID: f0e4b601-616d-4a5b-9583-1c7a558e5830:2^|^SQL4^|^Replica is 
 
inconsistent^|^DPM Protected^|^Replica^|^C:\ 
 
Resync and all is well again. 
 
4) FILEserver with about 200GB in 250K files looks to be working fine. No 
 
errors. I've got 13 days of backups plus shadows. 
 
Each server is in its own protection group. There are no request for 
 
additional pool allocations. In order to protect the failing datasets, I'm 
 
making a copy of each problem server's protected directory onto the 
 
FILEserver. This works, but doubles the network traffic.

David, 
 
We need to get the volsnap errors and DPM reports to understand this issue 
 
better. Please open a support case with PSS.

David - can you get these events (Volsnap provider i.e. Volume Shadow Copy 
 
Service) from the Event Log? That will help explain why the shadow copies 
 
are getting overwritten. 
 
Also, can you share the disk allocation info for these protection groups? 
 
Thanks,
