Thomas,

For now, at the 5.1.5 client level, it might be easier to put the
following in your include/exclude list:

   exclude.systemobject frs

This should cause systemobject backups to skip the FRS object, and avoids
the batch file method you mentioned.

You are correct, in 5.2 this will not be an issue.

Regards,

Andy

The only dumb question is the one that goes unasked.
The command line is your friend.
"Good enough" is the enemy of excellence.
