I'm a registered user of TI9. Backup a single a file and restore it is a great feature but it seems not to work properly. I've made a backup of "System" hive (registry) located in "C:\Windows\System32\config\" All went fine as well as its verification. Due to a boot issue I need to recover that registry hive. Using F11 I was able to restore that file successfully. However the boot was not possible and there was no error message (even the XP boot screen was not shown, just a blank screen). I had to go to the XP console and then recover that registry hive from a backup (copy) made with Registry Workshop. All went fine. I was able to start XP again. For me, the TI9 file backup is a great feature but it didn't work. Something is wrong. Maybe the support team could make a test with the same registry hive and then try to recover it (using F11...). TI9 version: 2277. I'm afraid what would happen when I need to restore an image made with TI9... Can I keep trusting in you Acronis?
