It looks like creating rdb failed. There might be already a RDB there. Did you select overwrite the RDB while restoring? Please upload the whole log if possible.

-Beta

I get this error prior to being able to restore.  It comes up when I try to browse the Granular Restore.

Here is the log

Anyone able to help?

The log shows the RDB - 2013_Archive_rdb - already exists. Please remove it and retry.

--Beta

Where is it. I can't find it in server anywhere

Can you run  Get-MailBoxDatabase on Exchange Powershell to check?

--Beta

Location says it is here

C:\Program Files\avs\var\avfscache\AVFSMOUNT\exch1\db\rdb_2013_Archive.edb

That directory is empty doesn’t exist at all.

Please delete this RDB and retry the GLR.

If it still doesn't work, please contact EMC support.

--Beta

you can only have 1 RDB at a time (Recovery DataBase) on the exchange server.

So if you look on the exchange server and you see the datastores that you back one.

one of them would be an RDB

that has to be removed before you can do another one.

So either you have one that was MADE, or one that got orphaned from a previous restore,

or you are trying to do 2 restores on the same exchange server...

rule of thumb,

Only one exchange restore per exchange server at a time

Always check to see if there is an existing RDB and find out of you can remove it.

I'm having the same issue,but I don't see where I could delete an orphaned RDB.  C:\Program Files\avs\var\avfscache is empty.
