My system config: Intel i7 2600K Biostar TZ77A Toshiba 128GB SSD WD 500GB SATA HD 8 x 2 DDR3 1600 Windows 8.1 Paragon Backup Recovery 2013 installation and backup were good. Right after backing up my system, I did recovery to try the recovery function. The system could not boot after recovery. Windows 8.1 installation disc could not repair it. I ended up with re-installing Win8.1 and all apps. I checked backup folder. There were more than one image file in the folder. The largest file extension is .000. Non of these files can be clicked to open. I didn't see any error message when I backup the system. What's wrong?
