Exchange 2013 Log files filling up

Hello,

I've recently deployed an Exchange 2013 server.

I noticed that the log files are filling up and I'm close to a full disk.

We back this server up using VMware related applications, so there is no backup software such as Backup Exec that will flush the logs.  Consequently, I understand Circular Logging will need to be enabled.

I've have limited experience with Exchange 2013.  Can I please get some concise information as to how I can enable circular logging on Exchange 2013, if in fact this is the correct course of action.

Once enabled, does the database need to be dismounted and remounted for changes to take effect?  Can this be done via ECP? Or only via Exchange shell?

Thanks in advance.  Very much appreciated.

Regards,
RealTimer

Hi,

Read here for how to enable circular log

http://geekswithblogs.net/marcde/archive/2013/08/09/enabling-circular-logging-in-exchange-2013.aspx

You will need to do a Full back up so Exchange can flush the logs with windows back up. or get another 3rd party software to back up Exchange.

The optimal way to do this would be to do a full, on-line VSS-aware backup of your Exchange database to purge all of the existing log files.  Once that's done, you can stop the Microsoft services and change the log setting to use circular logging without fear of losing anything.

Can backup be performed to a mapped drive using Windows Backup?

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

I haven't ever used Windows Backup to do this, but supposedly you can:

Yes you can, but I have never used it.

But if you could. upgrade VDP to Advanced version or take a look at the existing 3-party solution that are available on backup/replication market (like, Veeam Backup and Replication, DPM etc...) that does guarantee application consistency.

Can I move ANY logs files to an alternate location?  
E00.log is dated 4/8/2014 2:00PM.  I have a bunch that are from before this date and time.

You can change the log file path to somewhere else via EMS or Shell, just do not delete or move them manually.

Yes you can do as EEhotline says, but it will move all of the logfiles, not just some of them. They have to all be in the same location.

Thanks folks - I just wanted to see if I could move some of them temporarily elsewhere before I got the chance to either complete a backup or enable circular logging after business hours.  (To buy some time and address it before drive space was empty).

Thanks for all the quick responses!!
