    I created a full backup image with Acronis True Image Home 2009. When I select the incremental option, Acronis makes what appears to be another full image since it's even larger than previously created full backup.

    How do I fix this?

    What are the filenames for the image files?

    Have you run any defrag programs between the backups?

    What build of TI 2009 are you using?

    It is perfectly possible to have an incremental backup larger in size than the full original backup.

    This is just the way Acronis works - Defragmentation is the main cause as Acronis stores all the changes in file location.

    If you add a small new file of say 10k you wont just get an incremental file of 10k.

    I only do full backups.

    The file names? I deleted them days ago to make room on the backup drive. I don't know what that would have to do with anything. I always specify my own file names.

    I don't defrag often and didn't between the time I created a full backup to the time I created the incremental.

    The incremental was larger than the full and took just as long. What's the point in creating an incremental in that case?

    I don't know what build I have installed. I don't know how to tell.

    The point of the filenames is that TI will assign the name based on the Full or previous Incremental/Differential selected as the "base" image. By looking at the names, one can usually tell if TI is doing it correctly or if something else is going on.

    If you're giving each backup a name manually and selecting Incremental as the type, TI will be creating a Full every time because the manual name you used doesn't exist. Could this be what happened?

    To find out the build number, press the Alt key to display the standard menu bar and then select Help >> About.

    Hello all,

    Thank you for using Acronis True Image

    DoubleHelix, I assume that MudCrab found the correct reason:

    Thank you.

    Does this apply if you're using [ComputerName]_[Date] to automatically generate the file name? That's what I'm doing and I'm also getting what appear to be Full backups instead of Incremental.

    Is it even possible to have a weekly Full backups (say around 8GB) and then daily Incrementals, which should be smaller files? If so, how do you configure this scenario properly?

    Hello DavidSz,

    Yes, this scheme applies to method you mentioned.

    Yes, it is possible. In Acronis True Image Home 2009 you can set the option to create Full backup after N incrementals\differentials. Detailed information about this feature can be found in User's Guide.

    Thank you.
