Many thanks for the reply and explanation. Since I'm running out of disk space in my first stage repository, I will have to manually move around the Backup Folder almost daily to prevent backup failure.
Do you want to change anything in terms of retention?
So far all of the backup job is kept 20 backup. Not at the moment I do not plan to change or reduce them.
Which backup method are you using?
I'm using Reverse Incremental so I perform once Active Full backup and then the incremental forever for the next day until I need to make Active Full backup again.
Can I convert my existing backup set into Scale Out without doubling the disk space required ?
