I perform a FULL system and file backup at the end of each month. I back up to a 2nd HD exclusively for that purpose. I currently have 5 backup sets that are starting to eat my 2nd hard disk. I am unable to find any reference to deleting backup sets. Do I simply use normal Windows 'Delete' or ...what? While I usually jump in boots and all, in this instance, I am not willing to experiment in case I stuff my backups or Acronis' ability to recover a crash. Please advise and thanx!
