Incremental backup will NOT increment -- Always full backup.

I need a solution Win 7-64 SSR 2013 11.0.2.49853 up to date. 

I have an internal HD that I have a backup job to a FOLDER on drive "N". I am attempting to run incremental backup of an external USB drive to a different folder also on drive N.  I can not get the incremental back up to increment.  I ALWAYS get a new full backup set. The full-incremental backup is been indexed by one such as -002.v2i and -003.v2i each time.

Is the reason:

I am backing up from an external USB drive.  SSR does not write the VtrackDiskController or the .VTrack folder to the external disk.

Or is the problem that I am trying to use folders not partitions on the HD I store the backup.

    I have changed the way that I do backup and no longer backup the external drive.  Thus the problem is not solved but I have a work around.

    Which driveletter is assigned to the external usb drive you want to backup?

    The internal drive is "M" back up to a folder on "N"

    The USB external drive is "Z" back up to a different folder on "N".  I named the external drive Z so it would always be the same driveletter when I connect and disconnect it.

    How does SSR "flag" a sector or disk  that the sector has not changed?

    Afaik It does this by comparing at the block level but how exactly I have no idea, but i would assume by doing some checksum calculations.

    Do you have the verify option enabled? One reason for starting a new full backup automatically is, when SSR thinks it can't create a incremental. With verify on you'd be notified of this.

    The link above states "SSR 2011 does not like swapping of USB drives as a backup destination, especially for base+inc jobs. It is recommended to setup a separate job for each drive, or use the offsite feature by backing up to a fixed location and allowing offsite to sync to the 2 rotating drives."

    I do NOT want an EXTRA off site copy.  I have a "separate job" for the single USB drive I have.  I could not find a way to use the offsite feature for a SINGLE backup to a USB drive.
