Cannot open backup device. Operating System error 5

Question

Below is the query that I am using to backup (create a .bak) my database.

However, whenever I run it, I always get this error message:

Answer 1

SQL Server is not able to access (write) the backup into the location specified.

First you need to verify the service account on which the Sql server is running. This can be done by using Configuration manager or Services.msc.

or

Use below query :

SELECT  DSS.servicename,
    DSS.startup_type_desc,
    DSS.status_desc,
    DSS.last_startup_time,
    DSS.service_account,
    DSS.is_clustered,
    DSS.cluster_nodename,
    DSS.filename,
    DSS.startup_type,
    DSS.status,
    DSS.process_id FROM    sys.dm_server_services AS DSS;

Now look at the column service_account and note it down.

Go to the location where you are trying to take the backup.In your case : C:\Users\Me\Desktop\Backup

Right click--> Properties --> Security -->

Add the service account and provide read/write permissions. This will resolve the issue.
