Incremental File Backup remarkably big
Hello,
I established a daily file backup of my data files as incremental backup. The first backup then is a full backup, and it has about 4.68 GB. The next ones are incrementals, and usually have a size of about 2-3 MB.
But now I notice, that there are some incremental backups that have nearly the same size as the original full backup, e.g. 4.48 GB. And I did not do a lot of work on my data (I would have expected the usual 2-3 MB change), so it is not possible that all the files should have changed. Defragmentation is also turned off.
Any idea what could have caused this?
I am using Windows 7 64 bit.
Thanks, Thorsten

Yes, I know this. That's why I said that automatic defragmentation is not turned on. And I did not defrag manually, either. Can someone think of any other possibility? I don't know if file backups work different than volume backups. Do they also base on sector changes?

I have the same question. In my case I'm using Windows XP and backing up two different partitions. One in particular is not a system partition, has no temporary files on, and has hardly been touched between backups. Yet, this drive has increments of 140 MB and 310 MB.
As an example, I created an initial base backup of a 153 GB. I didn't touch the computer at all between starting the backup and a scheduled increment later in the day. The increment is 140 MB large. What can it possibly contain? There were absolutely no changes to the disk.
By the way, I've been using Norton Ghost for several years prior to my recent purchase of True Image. Norton created very small increments on the order of 150 KB for drives with no changes. Even if I changed a bunch of files, the increments were still typically under 1 GB. Meanwhile I'm seeing increments on the order of 1-4 GB for True Image even though hardly any changes have occurred.
I'd really like to understand if perhaps I'm using the wrong options, or if there's something I can do to reduce the size of the increments.

Norton recorded changes in the file. Acronis records disk sector changes.
Have you checked to see if the Windows Disk Restore is turned off. If enabled, this keep track of all changes to the syistem and can use considerable space.

It sounds like perhaps Norton has superior technology.
Windows Disk Restore? I'm 99% sure I don't have that enabled. Is it even an option in Windows XP? Where do I find it?
