Greetings all,
I'm interested in learning more about the specifics of backups.
When a backup is initiated which locks are applied to the database? Are the locks at the table level and come off and on as required, or is there a broader scope?
Additionally, when a database is backed up in online mode, and a record is written during the backup, does that record become part of the backup as well?
Are tables processed in order as they are backed up? Or is there some kind of parallelism in play?
I appreciate this is a set of questions, but any insight would be very welcome.
Thanks!
