Exchange 2013 transaction logs not getting truncated after the full backups

Posted on 2014-11-29
Last Modified: 2014-12-17
We have exchange 2013 sp1 installed on windows 2008 r2 standard server as VM with windows 2012 r2 datacenter as host server. The transaction logs are not getting purged after the full backup. we are using native windows backup application and are selecting the full vss option. Backup gets completed successfully but the logs are not purged.
We have to manually delete the logs to clear up the disk space.
We don't get any errors related to truncation of logs in the event log.

If you're doing a full backup of the server then the Exchange 2013 logs don't get truncated. Ran into this problem myself not too long ago - the fix was to run a custom backup and backup the volume with Exchange installed on it.

See the table at the bottom of this article for more information:

We were running the full backups earlier. We ran the backup within the exchange server, selected only the c drive, database drive & the log file drive. Our logs got truncated after the backup was completed.

Sorry ewp-admin but wasn't your solution the same solution that I suggested? i.e. a full backup does not clear the logs so you would need to perform a custom backup and select the volume with Exchange installed on it in order to clear the logs. You never stated that the logs were on a separate drive however in the article I linked in my previous post, it does state that you need to back up the drives that contains the Exchange database and log files.

It was not clear in the comment if we should run the backup from the host server like we were doing earlier or run the backup within the exchange server which helped us truncate the logs.
Creating a custom backup from the host server for only backing up the exhange volume /only databases did not solve our problem.
