VSS trace
VSS trace is the log information output by the VSS service (Volume Shadow Copy). The VSS
trace is used to identify problems among the requester, VSS service, and VSS Provider.
Settings required for collecting VSS trace and usage, are available at:
http://msdn.microsoft.com/en-us/library/dd765233
NOTE: Microsoft Windows Software Development Kit (SDK) needs to be installed in advance
as noted in the above URL. For the Transportable configuration, SDK needs to be installed in
an application server and backup server respectively.
Specify the VSS trace output destination using the -o OutputFile option of the command
populated when the VSS trace is collected. When VSS trace is collected, collect a file specified
in OutputFile.
Since the collection of VSS trace will start after populating the required command for the
E2002056command prompt, settings are required every time VSS trace is collected.
For example:
1. Open a command prompt and move SDK to the installed folder.
2. Populate the command.
For example: vsstrace -l 255 -o c:\vsstrace.txt
VSS trace will start after populating the command.
3. Execute the backup process and collect VSS trace. A collection of VSS trace is completed
when the command prompt is closed.
