Hi! I have problems backing up one of the partitions on my hard discs. It's one of those that don't change very often, so I made one complete backup image on DVD and now that some changes occured on this particular partition, I decided to make a differential. It has a capacity of 80GB, and at the time I made the complete backup, there was about 22GB used. Now, it is about 27GB with none of the old files changed. Oh and one more thing to explain: since direct DVD recording was not supported before build 3.641, I got used to leaving a copy of the last part of any complete backup on my backup drive (internal HD) and creating any differential backups based on this last part. This works perfectly fine on every other partition... However, on this one it doesn't. The operation of creating a differential is cancelled every time for the backup partition is full. Before, there is about 10GB of free space. So as you see, the differential would get really big, if it came to an end. I know that TI includes any changed sectors into the differential, but ending at a size of 10GB with indicating 20 mins left seems an awful lot to me for only 5GB that I changed by myself... Of course I could make a complete backup from time to time, but this would take a lot of time, so I don't really want to do it this way. Can anyone imagine, why the differential (only) on this particular partition gets that huge? It works perfectly fine on two other partitions and as well when backing up some files only (not a complete drive). OK, I hope some of you understood this If you need any more info, just ask... Thanks!
