Backup Errors for Citrix Servers with 4.1

Post by bakerte »

I have two Citrix servers that are getting the following errors during backups:

7 of 7 files processed

Total VM size: 60.00 GB
Processed size: 60.00 GB
Processing rate: 46 MB/s
Backup mode: SAN/NBD without changed block tracking
Start time: 12/29/2009 8:02:22 PM
End time: 12/29/2009 8:24:47 PM
Duration: 0:22:24

I cannot find what is happening with it as the other Citrix server backups are doing fine. Any help would be appreciated. Thanks

Try running the following two commands in the VM and see if output contains any errors:

Code: Select all

vssadmin list writers
vssadmin list providers

You are missing the "System Writer" in the list of VSS provider

Check this registry key:

Open Regedit and navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\VssAccessControl.
Change the value of NT AUTHORITY\NETWORK SERVICE (REG_DWORD) to 1.

Then reboot the server

Sorry to post back so long. I will do this and see what comes of it. Thanks again.

I looked at the registry adn did not find this key. Do I need to add it to the servers? Thanks.

Mmm no this key is referred to Windows 2008, you are running Windows 2003 so don't add it if you don't have the key
Instead, on Windows 2003 try this procedure:

net stop vss
regsvr32 /s ole32.dll
regsvr32 /s vss_ps.dll
Vssvc /Register
regsvr32 /s /i swprv.dll
regsvr32 /s /i eventcls.dll
regsvr32 /s es.dll
regsvr32 /s stdprov.dll
regsvr32 /s vssui.dll
regsvr32 /s msxml.dll
regsvr32 /s msxml3.dll
regsvr32 /s msxml4.dll
net start vss

The reboot and check if running "vssadmin list writers" you have the "System Writer"

Ciao
