Differential Sync Great for Large Files
Last September, the OneDrive developers announced that they were rolling out differential sync for all file types. Differential sync means that instead of having to upload complete files, even if just one word changes, OneDrive can synchronize just the changed bits. As files become larger, the advantage of differential synchronization becomes more important.
This facility had been available for Office files for some time, but not everything stored in OneDrive (consumer and business) is an Office file. The update means that all the other file types that people want to store in OneDrive and SharePoint Online now support differential sync, including PDFs, graphic files, audio recordings, and even PSTs. Obviously, some of these files are very large, so being able to synchronize just the changed bits reduces a lot of network traffic and makes the synchronization process much faster.
Slow Deployment Now Complete
Good intentions don’t always turn into immediate deployments and the roll-out has been slower than anticipated by Microsoft. However, on April 24, Microsoft announced on OneDrive User Voice that roll-out was complete for both commercial and consumer versions of OneDrive.
I am on the OneDrive Insider Ring, so the current version of the OneDrive sync client running on my PC is 20.064.0329.005 (Figure 1 – see this blog for information about OneDrive versions).
Speaking of versions, a feature that isn’t working so well yet is the OneDrive sync client’s ability to access the version history for documents. Apparently, the development group is working to resolve the reported issues and we might have a solution in mid-May.
Version history depends on the versions kept for documents in SharePoint Online and OneDrive for Business and the client should have the same functionality as available in the browser clients. For instance, you’ll be able to restore a document back to a previous version.
