Other customers have seen this issue as well, here are some additional 
suggestions we have seen from Microsoft. Since this is a Microsoft issue and 
the possible fixes noted below are from Microsoft Support, we encourage you to 
discuss the issue with Microsoft. 

Method One
-----------
When working another customer we discovered an issue with the System Writer not 
being available.  Microsoft engineer supplied these steps to fix it.  

# Please run following command to set default permissions explicitly on the 
COM+ Event System service.
{{{
sc sdset eventsystem 
D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)
}}}
# Then restart COM + Event System service in "services.msc".
# Try to query the vss writers again to see if the "system writer" appeared.

Method Two
----------
This is another method we have seen suggested to fix the problem.  

System Writer is launched as a part of the Cryptography service (cryptsvc). If 
that service fails to launch, System Writer will not show up in the 'vssadmin 
list writers' list.

The following is reported for Windows 2008 System Writer (after some recent 
updates were installed?) See the link:  
http://social.technet.microsoft.com/Forums/en-US/windowsbackup/thread/bb760434-de80-4cb6-ae9e-bd253e4b037c

Microsoft techs suggested the following workaround:

Overwrite WinSxS permissions as follows: 

Takeown /f %windir%\winsxs\filemaps\* /a icacls %windir%\winsxs\filemaps\*.* 
/grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX)

Stop and start Cryptographic service

net stop cryptsvc
net start cryptsvc

Verify "System Writer" showed up in list of writers using "vssadmin list 
writers"

Yes, we have seen this before.  We have a special check in the DR backup to 
make sure the VSS System Writer is present and working on the system. Please 
run the command "vssadmin list writers" to check if the System Writer is in the 
list.  If not, you will need to contact Microsoft as it's a Windows issue with 
a core VSS writer.

Thanks. Tried that. Unfortunately, I still do not see a "System Writer" in the 
list of VSS writers. Did this (ran it as a shell script):

Takeown /f %windir%\winsxs\filemaps\* /a icacls %windir%\winsxs\filemaps\*.* 
/grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant BUILTIN\Users:(RX) net stop cryptsvc 
Net start cryptsvc

Still no "System Writer" ...
