Enable differential sync (only sync parts of the files that changed)
Today OneDrive implements differential sync only for Office files (that is, syncing only the changes made to the file, instead of the entire file). It would be a significant improvement for this capability to work against any files in OneDrive - so smaller changes to a file would result in less data needing to be transmitted, meaning less time to sync changes back and forth, and more efficient use of network bandwidth.

We have completed the rollout for both personal and business users. Enjoy the better syncing!

After logging ticket with MS O365 support no one actually knows what build number contains the fix, all they can tell me is the fix is available in v20.064.0389.008 or before.
According to the roadmap it has been released.

I tested in v20.064.0329.0008 and believe its fixed. Release notes should contain what is fixed and what is new but seems everything falls into the Bug fixes and Performance improvements category. As BOOM! IT'S DONE has been commented by OneDrive team this post will probably go unanswered.

Does anyone know what build of Windows OneDrive for Business contains this fix?
Looking through the release notes and there is no mention of this anywhere:

This will be awesome for our windows users. Any chance that this will find its way over to the Mac land?
Thanks

I had to test this out for myself...and it seems to have worked as expected. I have a 5.7GB Adobe Lightroom Catalog that I have tried in the past to use in OneDrive. Before differential sync, it uploaded the entire file each time I opened Lightroom.
I dropped that file into OneDrive and synchronized. Then I updated the file by making a change in Lightroom and overwriting the existing file on OneDrive.
The user interface LOOKS like it is uploading the entire file again, and it took 5 minutes to churn through the file, but my network stats showed that little actual data was flowing to OneDrive.
Sweet! Thank you so much!

I'm also having to sync a whole PST file instead of sync at the moment with Onedrive on Office 365

Will the differential sync work on PST (DB files) files as well?

Differential sync is working great with personal accounts. Just made an change to one of my VHDs and only parts of it were uploaded (checked with external bandwidth monitoring tool, it doesn't show the size for the part that was being uploaded, the bar just moves faster). Its just for the ODFB users that was delayed (doesn't work yet)...

***- ODfB Differential sync was on the roadmap for Q4 2019. Now it's delivery is expected Q1 2020. FRUSTRATING.
And Randall Jr. below is RIGHT. MS is playing games. The big boys pay big money to get NEARLY working solutions, but not nearly enough. This type of capability should have been baked in from day 1. -

Do i get that right that all OneDrive personal users are already able to use this feature? Or did Gaia Carini mean by "our users" Microsoft employees?

## Differential sync for all files
----------------------------------
OneDrive is the files app in Microsoft 365 where you can work with all your files—your individual work files and the files shared with you across Microsoft 365—on PC or Mac, across browsers, and across devices with highly rated apps for iOS and Android. Improvements to sync include *differential sync for all files*—Office files already feature differential sync—which will accelerate sync and reduce network utilization, and support for Windows Virtual Desktop, currently in preview. These improvements enable organizations to deliver cloud-connected experiences and users to work with cloud files within native experiences like File Explorer and Finder.

--------------------------------------------------------
Differential Sync saves time and network utilization [roadmap: 33412]
Differential sync brings the ability to sync only the parts of large files that have changed, not the entire file. This makes the file synchronization process faster for these files. Currently OneDrive supports differential sync for Office 2016 files. Later this year, we will bring the ability to leverage differential sync to all file types stored in OneDrive and SharePoint.

Lol Randal, what a rediculous comment. So the reason differential sync is such a difficult problem is due to the various layers of encryption that are used to protect our files which are stored in OneDrive. Great news though, this should be marked as in progress, there was just a demonstration of this last week at SharePoint conference. It will be released by the end of the year.

I think I found a explanation. They didn't allow differential sync to discourage the sync of large files. So they can offer a bigger storage, with less actual server storage. It's like a flight overbooking, they share the empty space across more users.
The fewer big files that are less accessed, cause of the bandwidth requirements, are kept in cheaper and slower storage. They win on both sides.
