File backup/sync with verification?

I'm putting together a seperate box to backup my ESXi file server which will be running Windows, and I am looking for a automated (I setup what/where/how once and it does it itself from then on) backup/sync program that will copy the files and verify that the source and copied files match (via SHA or MD5 for example). Since this will be over the network between 2 physical boxes, and the files will easily total in Terabytes worth of data, I'm hopeing someone knows of a server/client backup/sync software that can keep track of the file hashes on each individual physical box, so that when it comes time to do the backup/sync, it will just compare the hashes instead of actually reading the files over the network. This way, after the first backup/sync, any future backup/sync would take minutes instead of days to perform.

You can do it in the Task Scheduler built into Windows. It is in the Administrative Tools in the Control Panel.

This combined with freefilesync would be fast in terms of backing up, but it does lack the verify option you want.....

I can do a simple file sync and automated timed syncs with just SyncToy, but file verification would have to be done manually. Most of what I found simply verifies that the backup is valid, but doesn't verify if the backed up file matches the source.

I was originally searching for 'backup sync file verification sha md5', yada yada yada, in Google. After typing the original post up, I got to thinking of other searches to do. Going back to Google, I searched for 'server client backup'. Lo and behold the first link seems very promising, with UrBackup offering a "paranoid" option that will verify file hashes. Going to test it out and see if it fits the bill.
