As other's have stated your transaction logs get automatically deleted when the information store is backed up successfully.
Circular logging resuses existing transaction logs creating a total of 5 transaction logs with a total of 5 MB each in a round robin use. So when log 5 files up it goes back and reuses log 1. The problem with this is that if you have a database failure you will only be able to restore the database to the point of the last successful backup effectively losing whatever was in the database after the backup. If circular logging is turned off you can restore your database and then using the transaction logs "replay" until you get the database back to where it was just before the crash. If you have the space I strongly suggest you do not turn on circular logging.

If your getting a large collection of transaction logs, that means you are not backing up Exchange. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Douglas M. Long Sent: Tuesday, April 05, 2005 11:11 AM To: [email protected] Subject: [ActiveDir] OT: Exchange Transaction logs Just had a couple of questions about a couple things I can't seem to get a straight answer for. Is there a recommended length of time to hold on to Exchange transaction logs? Is there any reason to keep transaction logs around any further back than specified in the checkpoint file? Is it typical to enable circular logging, or does this somehow get you into some issues if a disaster does happen?
