If you backup the database with a Level 0 every six hours, then do the archive logs in between, every 15 minutes perhaps, what benefit would I have to incorporating a differential backup? Essentially, full backup only with archive logs x minutes. Particularly cumulative. Is it only because of disk space?
I have read this,
But it did not help, as it includes a differential.
Edit: I ask because I thought you had to have a full backup to use a differential in the first place. So why not just have the full backup to begin with?
