Does Robocopy Support Changed Block Tracking?

I'm looking to replicate my VM backups (created using Veeam Backup and Replication) to my DR site and am wondering if Robocopy supports changed block tracking.  That is, if only a portion of my backup file changes, will Robocopy try to sync the entire file?  In my case, some of my backup files can be rather large.  I know I can do this with rsync, but I'm looking at all my options.

    Nope, sorry; if robocopy sees a difference (file size or date/time), it copies the complete file again.

    Double-take would do it but you have to pay for license
