Q:

default service account for maintenance plan backups on SQL Server 2012

What is the default service account used for backups created with the Maintenance Plan Wizard? I am trying to put the backup files on a share on a different server, and that service account will require access to the folder there.

A:

If you run a BACKUP query under a certain Windows/SQL Server account, it is actually the SQL Server Agent account which "does" the BACKUP and needs full control permissions to the UNC path (see here).
