Well the q event, like the level 2 tech mentioned, only reports on whether
the batch command started successfully, not on whether the actual tdp
commands within the batch were successful. If it is tdp for exchange you are
trying to monitor, you may want to try and do a 'q act begint=whenever
msg=4991'. This will show you when the tdp sessions start and end and also
how much data was backed up. Ps: change the whenever to whatever time you
want to start looking from, I usually put 00:00 to start from midnight.
