I'm seeing a rather large number of machines lately with System Volume Information folders ranging from large (50G) to huge (350G), on both desktops (Windows 10, various builds) and servers (2012R2, 2016, 2019). I have ways of clearing them fairly well established, but preventatives aren't there yet. I'm using Optimize-Volume in multiple ways and doing other things too, but it's not doing enough, they fill back up. I'm theorizing that Windows is just making demands which the storage cannot fulfill. Anyone have a way to throttle Windows to match storage, rather than trying to extract more capability out of the storage?

Edit: Please note that I'm not talking about storage space, I'm talking about read/write/seek "horsepower". Windows appears to be using VSS as a kind of cache, and orphan shadows are piling up when demands go stale. I'd rather throttle Windows somehow, or many different somehows, so that the demands slow down, rather than go stale.

There are several things (usually system processes, but not only) which can take up space in the System Volume Information folder.

How to stop them from doing that depends on the specific cause.

There is no "global" way to tell Windows "just don't use so much space on that disk".
