Now that I have Paragon Backup 10 Professional I want to download a full backup of my system to DVD (to keep on hand ... not for incremental backup) and I also want to download WINPE. Does it matter if I use DVD+R or DVD-R ? I have both. Is one preferred over the other for backups? And if there is a reason for selecting one over the other could you tell me why. Tnx from a rookie.
