Deleting Exchange 2007 Logs

Hi,

I just realized I have only 7.5 GB left on 200 GB dedicated disk space to Exchange Database/logs

I use NTBackup but from another server (2003 Enterprise), as exchange 2007 doesn't support ntbackup. I have been backing up by selecting the location of exchange database/logs drive from the network tree using NTBACKUP thinking it would do the trick. well it didnt and I afraid im going to run into problems. I know I cant delete them by hand either....

What can I do quickly to resolve this issue??

Thanks

You can temporarilily enable circular logging.  This will clear out your Exchange logs.  You should not delete them manually as this can cause problems.  Once the logs have cleared out you can disable circular logging again.  It should only take a few minutes for the whole process to complete.

Dismount the DB during off hours and do a copy of the db first and then delete the log files.
This would save you since you do not have a full backup incase something happens.

Ok everything is up and running again, disbaled the circular loggin and now i have an additional 50 GB total of 100 GB. however I still see logs from july 2010.

Reason why I couldnt mount, was that I was connected to exchange via RDP use vpn and exchange services were set to start by local access. I had to start all automatic services manually to mount the database.

Still need  a permenant fix for the logs...
