changing backup scheme
My question concerns making changes to an existing scheme. I recently created a differential scheme for a full backup after each 6 differentials and a clean up to keep the latest 7 backups. After the initial Full and 2 differentials were created I changed the scheme to a Full after 3 differentials and to keep the latest 4. I thought it would then just create 1 more differential and then another full but it didn't. The next backup was a full backup. So, I am asuming that anytime you make ANY change to the scheme and hit the save button it resets the scheme to start over from a full backup and it just ignores any previous backups that have been made, and those previous backups will then need to be manually deleted. Is this correct?
