Windows 11 25H2 "Point in time restore" seems to reset System Protection to 2%

I'm experiencing the same behaviour on all my systems, which has BROKEN how Synology Active Backup for Business (ABFB) functions. ABFB still works, however, it's now incapable of doing incremental backups to our Synology NAS, likely because it relies on the Disk Space Usage setting in the Configure menu on the System Protection tab of the System Properties window. (Run the "sysdm.cpl" from the Run... box.)

ABFB backups now copy the ENTIRE disk (usually around 400GB) over the network for every backup job, instead of an incremental backup (much smaller 60-120GB depending on how much data has changed). I also worry the Synology NAS is no longer de-deduplicating the data (and therefore taking up way more space), but it hasn't been long enough to identify a storage trend yet.

Like stormin​, I share the same questions. Until answered, our backup strategy has been affected by a decision Microsoft did not communicate in a way that I saw it. This is absolutely unacceptable as it breaks a workflow critical to everyone using Synology ABFB to backup their computers.

What will Microsoft be doing to resolve this impact for Synology ABFB users?
