Exchange 2007 log files

Hi guys,

I have an exchange 2007 server that's running out of space, the log files are on a NAS (M drive), however they are not purging. The backup is running on the C & D (Exchange databases are on D). Should the log files be purged with the backups even though they're not on a backed up drive (the exchange databases are on the drive). We are using Windows Server Backup (Server 2008).
If I turn on Circular logging, what will happen with the current log files?

Thanks

Enabled Circular logging ... restart Information Store service - once you do this all log files will be flushed and new ones created.

Disable circular logging and restart Information store service ..... good to go

does it try and commit them though? i'm worried about not having the space for them if it needs to write them...
If you enable circular logging all the logs will commit to the database .

U have to restart Information store to get affected.
Log files automatically get committed to Database .... when you Enable Circular logging it will keep only the last 5-6 logs including E00.log and then run with only 5-6 logs with Overwriting log files with FIFO.

You can try to dismount the Database making it clean shutdown and then Enable Circular logging and restart IS.

As the logs will be committed to your database , you can move the committed logs to different drive to save ur disk space.
If you enable Circular logging and restart IS you wont have any logs apart from 5-6 .
Thanks Rancy - appreciate your help. Will try that tonight.
