I have a question related to SQL restoration process.
The environment is v8. Enterprise Plus edition.
All of the SQL servers are in Simple mode, with AD authentication, and the user that I am using for the backup process is domain admin and the access to the databases is all right.
I have a different backup jobs with different SQL servers in them.
All of the jobs are with AAP enabled and VMtools quiescence.
There are no errors through the process. All finishing successfully green

For some of the servers, everything is fine. But for some of them, when I try to restore SQL DB using “Restore application item” the console is open, but there is no DB in it – it is empty. And for some of the servers I have several dbs. For example 3 dbs and 2 of them are showing and 1 is missing.
If I try to mount the DB manually, using Restore guest files, and after that SQL explorer > add the DB - it works (except the newer than MS SQL Server 2012 Express Edition databases - I know for the staging limitation).
So what can be the reason for this behavior?
It is no version problem (I think so), because I have a SQL2008R2 DB which is ok, and 1 which is not.
It sounds like a permission issue, but the user is domain admin with access to the databases...
Any idea is welcome!

Thank you
