I just purchased TI 10 a couple of days ago. I have two internal HDs to be backed up - 250GB and 115GB. I have two 320GB USB HDs to backup on to. I wish to perform an initial FULL backup - but using DATA mode so that I can exclude certain directories that I don't need backing up. I am trying to schedule a backup of my C: Drive (250GB - only 200GB used) to my Q: Drive (320GB External), and my K: Drive (115GB - only 80GB used) to my R: Drive (320GB External) - C: Drive and K: drive backups to happen on alternate days with an initial full backup followed by differential. However, my PC freezes during the phase that TI 10 uses to read the data. The backup doesn't start. I have to use the reset button to restart my PC, and the TIB file is ALWAYS 0KB. I have emailed support but had no response. I am able to use my PC for hours and hours without it freezing, so I don't know why TI 10 should cause it to happen. I have approx 50GB free on drive C: and I'm running on XP Pro SP2 (not on a domain) with 2GB RAM. Could there be a solution or do I get a refund?
