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.
