Capturing Logs From VSS-native

Each time TeamCity starts, it creates a new instance of the vss-native.exe file and places it into the <TeamCity Home>/temp directory. The name of the copy is generated automatically and uses the following template: TC-VSS-NATIVE-<some digits>.exe.

To manually enable detailed logging (for debugging purposes) for VSS Native:

  1. Copy the <TeamCity Home>/temp/TC-VSS-NATIVE-<some digits>.exe file to any directory.

  2. Run the program with the /log switch.

To get the command line syntax and options reference, run the program without any switch.
