I am a little nervous about relying on a disk backup performed by the desktop version of Backup & Recovery 14 Home that I am using, a backup that is taking place while potentially any number of processes could be changing the drive while the backup is taking place. Unless B&R is able to and locks the whole drive while the backup is taking place, the final backup is not an accurate snapshot of the drive in a point of time. For example, say the program has backed up "tracks" 1-100 and while it is backing up "tracks" 101-200, a process changes "tracks" 1-100. If the content of "tracks" 101-200 depend on/ are related to the content of "tracks" 1-100, they are now out of sync. So instead of the final backup being a single snapshot of the drive in a point of time, it is a series of snapshots, at different times, of different locations of the drive, any of which could have changed after that location was backed up. I assume that when a backup is being performed using the PE boot media, the booted OS is not writing to the drive being backed up and therefore avoids this issue. I also assume that since I have not heard of anyone complaining that backups of this nature using the desktop version of the program, do not restore a drive properly, I must be missing something in my understanding how this works. Does anyone have any insight on the reliability of a backup performed by the desktop version vs the PE boot version? The former has the advantage of convenience while the latter "seems" not to have all the same bells and whistles.
