My guess is that you are mounting up the filesystem, and backing up
the files directly.  The log files in Exchange are probably getting a
new name as they are truncated, which means that there are no versions
of the files, only a single version that goes from active to inactive
when it is deleted from the server.  Check your "Retain Only"
parameter of the TSM Exchange Management class.  Make sure that this
is set to 30 days and not 365 or nolimit.  This should delete older
files, but only from the date they get marked inactive.

We use Copy Services instead of the TDP for EXCHANGE.  We want to
keep backups for 30 days, which does work.  The .edb files are daily
marked as inactive and roll off as expected.  But an examination by
Mr. Exchange shows that there are .log files which are never marked
as inactive, and, thus, are immortal, so far to the sum of 50 Tb on
site (and the same offsite).  We obviously missed something in
configuration, but what?

To complicate matters, we tried to modify the client to allow
deletion of backups (Mr. Exchange discovered on his own that "del ba
*log todate=current_date-30" will get rid of the unwanted) but keep
getting the client is accessing the server message, on an empty
machine.  While waiting to figure this out, we could do "del vol xxx
discarddat=y" on all those volumes more than 5 weeks old, but there
must be some way to prevent this in the future.
