Im trying to figure out how best to sync updates of a file from 1 drive to a remote SMB share. There is a catch though, where its not possible to just do a simple append type of operation as its quite possible the last few hundred or even thousand/mega bytes of the last updated file on the SMB share are outdated as they may have been updated locally.
Would rsync be a viable method in this operation? How about if my file grows to multi-terabyte sizes?
Or is there a better option?

I did initial sync; got reported that "total size is 101,094,866,944". after the app wrote 100MB I stopped it then did the rsync simulations/dryrun using using "-n --no-whole-file --inplace" options to force delta since my src and dst paths are filesys paths (though the smb directory is a remote SMB mount) total size is 101,222,182,912 So it would just resend EVERYTHING all over again, although only 100MB of data was added. Sure enough after running the command w/o the -n switch its chugging away at the entire thing. or am i doing something wrong that is keeping diffs from being used?

Depending on the options you use and the amount of processing available this can work, but I never found it satisfactory. (I think --partial --inplace --sparse) You need to be aware of consistency issues - ie changes while rsync is in prigress. Using LVM snapshots can help with this if neccessary.
I tend to use block replication instead. Its a different paradigm, but zfs does streaming replication, as does dDRBD (may need a proxy) or MARS (very fiddly). The partial alternative is to use multiple drives - a smallish boot drive which is fairly static and a data drive whise contents is rsynced. Alternatively for database servers, I set up replication - which can be augmented with point in time recovery.
