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.

Does Robocopy Support Changed Block Tracking?

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.
