SQL T-SQL Backups


I have a simple full backup job on my SQL 2012 Server that overwrites after every job as seen below.

I need to modify it so that it overwrites only once a week.

I would either use retain days = 3 or expiredate somewhere but not sure if that will fit my stated goals for a rolling backup method?

Backup database Orion
To disk =  'd:\Orion.bak'
With init, format;

Thanks again

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

why not set the job itself to only run once a week ?

You'll need to create a weekly job for the overwrite the file backup and keep the daily one as it is.

Created two backup jobs but realized I can also do a maintenance cleanup task to delete old files as T-SQL doesn't have that functionality
