We are migrating from Exchange 2010 to Exchange 2013.  We have installed the Exchange 2013 but it only has a couple of mailboxes on this server, all the mailboxes are still on the Exchange 2010 server.

I have run a Windows Backup of the Exchange 2013 but I am still seeing a ton a log files in the mailbox folder.

Also the database file is only about 1.1 GB but the backup is now 40 GB.  

Is there something that can be done to truncate these logs and make the backup smaller?

Hi ,

1.Does the full backup completed successfully ?

2.what about the status for the below mentioned command ? Does the mailbox database headers updated with the latest time and date ?

Get-MailboxDatabase -Status | ft name,*full* -au

3.Just check the application event logs for the event id  2046  and that should state that the log truncation for the mailbox databases has been initiated or not.

4.Before initiating the backup just make the exchange writer is not on error.

vssadmin list writers

In case if it on error state ,please restart the Microsoft exchange replication service and check the exchange writers status again by using the above mentioned command.

Hi,

Is there any update with your issue?
