I have been running the same version of Bacula on a Windows 2k12 server for 
over a year (5.2.10).  A few weeks ago, we started getting all our jobs failing 
over the weekend due to an apparent issue with VSS.  Has anyone encountered the 
following fatal error:

20-Apr 19:30 bacula-zha JobId 5546: Start Backup JobId 5546, 
Job=Software_Share_Backup_-_Encrypted.2015-04-20_19.30.00_41
20-Apr 19:30 bacula-zha JobId 5546: Using Device "FileStorage-software" to 
write.

previously written, moving to end of data.

"zha-software-encrypted-vol0360" size=1775302040
20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS API failure calling 
"CoInitialize". ERR=Unexpected error. The error code is logged in the error log 
file.
20-Apr 19:30 fs01 JobId 5546: Fatal error: VSS was not initialized properly. 
ERR=Cannot create a file when that file already exists.

20-Apr 19:30 fs01 JobId 5546: Fatal error: VssOject is NULL.
20-Apr 19:30 bacula-sd JobId 5546: Elapsed time=00:00:06, Transfer rate=0  
Bytes/second
20-Apr 19:30 bacula-zha JobId 5546: Error: Bacula bacula-zha 5.2.13 (19Jan13):

The only way to "fix" this is to reboot the client.  Items I have tried:

* Restarted the Bacula service on the client - backups still failed
* Tested connection to client using the 'estimate' command, success. Issue 
isolated to Windows server. 
* List current VSS instances via cmd prompt (vssadmin list writers) - All 
states reported as Stable / No writers reporting errors 
* Manually create a shadow copy on the client (vssadmin create shadow /for=e: ) 
and then manually remove all shadow copies (vssadmin delete shadows /all) - 
backup still fails
* Ran System File Checker (sfc /scannow) - No issues found, backups still fail


After rebooting the client, backups using VSS work fine for a few days and then 
start failing with the same FATAL error.  It is not always the same job that 
fails first.

On the client, these entries are logged in C:\Program 
Files\Bacula\working\zhfs01.trace
  fs01: vss_generic.cpp:366-0 VSSClientGeneric::Initialize: CoInitialize 
returned 0x80070008


If anyone has any ideas on how to further troubleshoot this issue, or have 
encountered this before, I'd greatly appreciate it.[/img]
