Exchange TRansaction log files on Vmware (vmk files) getting too many and running low on space

Hi guys,

I am running ESxi server and hosting an exchange 07 on a virtual machine.  Issue is that I have got 35gb of transaction log files.  I am running Windows NT Backup every week and evidently the NT backup is not flushing these logs like a 3rd party solution would.  Right now we dont have resources to buy any 3rd party product but would like to know how to flush these logs by hand.  I heard the ESEUTIL might be able to do this.  Want to know any alternative ways if any.

eseutil will not flush the logs, you have two options
1. a full backup of the storage group
2. enable circular logging, then disable

if you enable circular logging without a backup there is the potential for data loss

Make sure you run NTBackup from the exchange server and choose the information store and not just the edb files.  As long as the backup is successful it should truncate the log files.  The exception is if you are running a ccr cluster and backing up the passive node.  NTBackup does not support vss so that would not work.

So sounds like running a full backup tonight would be the best idea?

Yes the full backup is what will truncate.  If you do an incremental every week it will leave them there.

yes, full backup is the best course of action
you can run a full backup one day and incrementals every other day (incremental will truncate once a full has completed)

Yes, thanks endital1097. I should have been more clear on that.  The incremental will work if there has been a full backup.  It is usually easier to just run full backups and be done with it though unless they take significant time.
