Unable to restore a .bak file in SQL 2012

Question

Environment: SQL 2012 SP1 Standard on Windows Server 2012 R2 Standard (Hyper-V instance on 2012 Standard)
I've been trying to restore a backup file that was updated on another system by our vendor (Omnify)
I'm getting the error: Omnify5.mdf cannot be overwritten. It is being used by the database Omnify5
I've tried putting the database in single user mode, Ive tried taking the database offline
I've tried rebooting
I've tried the following code:
use
Master;
GO
alter
database omnify5
set
single_user
with
rollback immediate;
alter
database omnify5
set
multi_user;
Go
And I've checked file permissions
I've verified the BAK file
I've re-created a backup to see if I could restore using it and still no joy.
Anyone have another idea?
Thanks

Answer 1

It looks like the file is still accessed by some other process, make sure that the file is no longer connected with any other database
select name,physical_name from sys.master_files
Take the database to single_user
Take the database offline
Put the database in multi_user mode
Restore the database with overwrite option ( You can either use SSMS or Restore command)
RESTORE DATABASE PowerSQL
FROM DISK = 'f:\PowerSQL\PowerSQL.bak'
WITH MOVE 'YourMDFLogicalName' TO 'F:\SQLData\PowerSQL_Data.mdf',
MOVE 'YourLDFLogicalName' TO 'F:\SQLLog\PowerSQL_Log.ldf'
WTIH REPLACE, MOVE
