Some VSS writers didn't freeze within 180 seconds.

E18.MULTIFLUSH : MultiFlush_LoopAndLock: VSS_FREEZE_FAILURE

Resolving the problem

Increase the VSS freeze timeout by adding the "timeout" parameter to FastBackClient.ini:


    [VSS]
    timeout = 360

The value of the parameter is in seconds.
After editing the FastBackClient.ini, restart the FastBack Client service.
