I need the advice of the experts around here... I have successfully created a full backup image to my NAS device on my LAN, verified, etc. I have scheduled a weekly incremental backup to take place to the same NAS device. My question is, in 6 months from now, I will have a full backup image and 24 incremental backup files. What files would I need in order to completely restore a failed hard disk with the latest data? Would I just need the original full backup and the latest incremental or would I need the full backup image as well as the 24 incremental backups? If I only need the full image and the latest incremental, would it be safe to periodically delete the older incremental files? Thanks in advance for your insight.
