SQL Server Agent - Job ownership
I often see SQL Server Agent jobs owned by user accounts.
These could be SQL logins or Windows accounts.
I like to have all jobs owned by sa (or whatever you have renamed the sa login to, or if you have disabled sa then whatever account you have created with sysadmin privileges that is not going to get deleted).
The problem with jobs owned by user accounts is that if that user gets deleted from the SQL Server and/or removed from your AD then the job will stop running.
Not good, especially if those jobs are your backups or maintenance.
So follow best practice and change your job owners.
