SQL SERVER – FIX – ERROR : Msg 3201, Level 16 Cannot open backup device . Operating system error 5(Access is denied.)



Recently I formatted my computer and installed fresh SQL Server in it. I installed AdventureWorks database in my database. Once done I wanted to run few test scripts on my database. Just like every DBA, I decided to take backup of my database – this way I can restore it back to attain original database state. As soon as I ran the backup command I ended up with following error. This error is due to permissions issue on the local disk and user account which is running SQL Server.
Msg 3201, Level 16, State 1, Line 1
Cannot open backup device ‘C:\AdventureWorks.bak’. Operating system error 5(Access is denied.).
Fix/Resolution/Workaround:
I checked which user account my SQL Server services are running.

I gave full permission to that account to get read of the error.

NOTE: This whole experience was done on the my personal machine and not on production server. Please check with your network administrator for permission on production server.
