Synchronous vs Asynchronous backup

  • If I have in my plan to backup all databases, and schedule it for a specific time, is the backup process asynchronous?

    Does each database start backing up simultaneously at scheduled time or do the backups happen in a pre defined order?

  • Depends whether you use one job with multiple steps or multiple jobs.

    A single job with multiple steps will be synchronous, each step starts when the previous one ends

    Multiple jobs are async, each job will start at it's scheduled time.

  • Thank you. When I asked, I was thinking of the Maintenance Plan route, where you select all databases you want backed up. I guess in that scenario, they will be added as steps..

    Single step synchronous if memory serves me right. It just creates an internal loop script that goes to each database in turn.
