Hi, NEW user here as well. Just purchased FD-ISR a couple of days ago. Pardon my ignorance, but I have read the user manual and some things are still unclear. I would appreciate some help with the following questions: a) How do you UPDATE the "Primary Snapshot" with another snapshot? b) How many "Snapshots" are recommended? -currently I have TWO (1 daily update/backup snapshot and 1 weekly updated snapshot). The size of my HDD is 80GB, so is 2 enough? c) How do you refresh a BACKUP Snapshot before installing a new program/making changes to your system? d) I also use PERFECTDISK (latest updated version) to defragment my drive. Is it SAFE to perform an OFF-LINE BOOT DEFRAG with FD-ISR installed.....OR should you just use the "Smart Placement" option only? e) Is it recommended to ARCHIVE one of my Snapshots (ie my "Weekly" snapshot), or is this not really necessary? Sorry for all these questions. I just want to make sure that I fully understand this great program. Thanks in adavance for all your help and support!
