I downloaded the trial version in December. I did a disk clone at that time. It may have been a full disk backup, I am not sure of the difference. My used space is 23.5 GB. I have a Dell Inspiron 8200 C:\ with a 200 GB Sata drive Backup D:\ connected via 1394 cable. My goal is simply to have a full backup, then do incremental backups every time I shutdown my computer. In February, I decided to purchase version 10. I have build 4871. I uninstalled trial version and installed 10. The first thing I wanted to do is an incremental backup. I asked it to do that on Feb 7 and it created a file on the root of my external backup drive and made a file of 19GB named backup.tib. Again on Feb 9 a file of 600MB named Backup2.tib. Again on Feb 17 a file of 13.4GB. Each time I went in the backup wizard and chose backup My Computer, then checked drive C (main), then chose D (backup) for backup archive location. The problem is that changes that I have made since the December backup are not showing up on the D: drive even after the 3 backups since then. I believe my problem is in how I executed the "backup archive location" step. There was no tib file to be found on my first incr backup after the initial trial backup(maybe bacause I did a clone?). I think I just chose D: as the location. The second time I think I chose the now existing tib file created on my 1st incr backup. The third incr last night..I am not sure what I chose..I was really tired. So what did I do wrong and what do I need to do to fix it? I have since sent some critical files manually to the D: drive in case something bad happens before I fix this. I have also downloaded the latest build and plan on uninstalling the old build and fresh install the new one, but I will wait until I get some direction on this issue. Current C: 23.45GB, Current D: 44.7GB (from explorer) During backup, at "partition selection" ATI says disk 2 (D) has 31.89 used space. Disk 1 correlates to explorer used space.
