Hi, under what context sql server agent service account and sql server service domain accounts work. What are the minimum permissions they should have to work normally.

( In the context of domain accounts).
if you are installing sql 2005 or newer, the installer sets the domain account up with the permissions that are required to actually run SQL Server. It is a best practice to split the SQL Server service account and SQL Server Agent accounts, so each only has the rights that it needs (create two domain accounts and specify each one at install time).
As your backups will generally be jobs in the SQL Server, they would be run by the SQL Agent service account by default (you can specifiy a different user is you want). The user you choose would need permissions to connect to SQL Server, they would also be ideally made a member of the database role
The user doing the backup would also need access to a backup location, be that local to the server or a network share on a fileserver.
It can make sense to make a special SQL Server backup user in your AD for this purpose alone. The user would be made a member of the
One further tip to ensure that the backup user you create is always setup for new databases would be to add the backup user to the
