I use Paragon Backup & Recovery 2012 Free, and I am in the process of upgrading from XP to Windows 7. I have XP on my first partition, Windows 7 on the second (my data happens to be on a third), all on the same physical disk. I would like to fully understand what I need to backup in order to correctly restore in the case of a total disk failure. Put simply, my understanding of my boot process is as follows: 1. BIOS locates MBR, which in my set-up above always points to the Windows 7 second partition. 2. Code in Windows 7 second partition, gives me my ‘select operating system’ screen. 3. If I select XP, then the XP operating system in first partition boots. If I select Windows 7, then the Windows 7 operating system in the second partition boots. If my above understanding is adequate, am I correct in thinking I could simply backup the MBR, plus partition one (XP) plus partition two (Windows 7), and this would be enough to fully restore my system. However that’s a big backup and XP over time will hardly change and become less important? So am I also correct in thinking that I could separate my backups, e.g. backing up MBR plus partition one (XP) separately from MBR (maybe) plus partition two (Windows 7). In this way I can backup Windows 7 seperately more frequently? Then using the recovery CD, so long as I restore MBR plus partition one from my XP backup image file, plus partition two from my Windows 7 backup image file (completed before I attempt a PC boot), I can successfully restore and boot using a new blank disk? Of course I am assuming my partition sizes remain static between any separate backups, otherwise clearly I may have to start from scratch. Would the purchased version of Paragon Backup & Recovery give me any additional facilities or indeed is it necessary here? Many thanks.
