Exchange Backup Failed

I changed the volume of my log files from L to M.

So I changed the information in database properties and moved the log files to the new location using EMC.  Since then the backup as completed with warnings.  The error says "System cannot find the path specified". I even deleted the backup files on the network share and started fresh but the backup still failed on the same F drive, which is where one of my mailbox databases are located.

But in events manager there is a an event id: 9782 saying that VSS has completed a backup of the database (including the database in the F drive). And the log files for this database will not be truncated.

I did a VMware vmotion just before the first backup started.

Any ideas?.

I forgot to add that I did a VMware vMotion just before this.

Repeat and test again, not a good idea, to vMotion before a Backup it's about to start, because the Snapshot process will quicse the machine using VSS also, if you got two processes trying to use VSS, it's likely to fail.

Check Backup again, and see if you can generate the same fault, without vMotioning! (this time)

Well the vMotion was not running at the time.  The vMotion was completed a 4pm yesterday and the backup started at 6pm.  I ran it gain today and it failed again.

I must add that the first vMotion failed due to insufficient disk space.  So it created a separate folder. with an "_1" at the end.

And the wired thing is it that it only failed on 1 volume twice?  Cannot find specified file path?

do you still have an F: drive attached to this VM?

Yep and after the vMotion completed I increased the vmdk file and migrated some users over to it?
And a user that is in this databased located on the F drive emailed me today.

vMotion failing due to insuffucient is odd, because unless you did a storage vmotion, in a vmotion the data doesn't move, although it would create a snapshot. But for it to fail, you must have been very low on space, less than 15%?

It was a storage vmotion actually, sorry to a new datastore.

Changed Volume of Logs without changing Backup.

Never a good idea, to vMotion or Storage vMotion, when you are running a backup.

I did change it, but I didn't remove it completely and start fresh, which is what I did last and it worked.

Seems to be ok now, thank a lot, expert!!
