I'm using Acronis True Image Home 11, build 8101. I have a task for incremental backups, with a full backup after 4 incremental backups. However, it does a full backup every time. I've read that this can result from defragmenting, but I don't think that's the problem, as it's the same with defragmenting turned off. Also, in the log, it always says "create full backup archive." I've checked the task repeatedly, and it's set up for incremental backups, but those never happen. I should point out that I use the Windows task scheduler to run the task rather than the Acronis scheduler, as I don't use a Windows password (the Acronis scheduler requires one to function). Any idea what I'm doing wrong? Thanks.
