I created a Copy Backup job in the spring of 2016 for a file server. I have restore point archiving turned on, set to keep 4 weekly, 3 monthly, 4 quarterly, and 10 yearly backups. Right now my oldest backup is from April 2016 and is marked as a quarterly. I'd like to change that one backup to be treated as a yearly so it won't be deleted when the next quarterly is generated. Is there a way to do this?
