Can't say I'm sure about the actual space usage, but the subsystem is "Shadow Copy". https://en.wikipedia.org/wiki/Shadow_Copy

That’s a low level mechanism that is used to implement consistent backups, (comparable to e.g. LVM snapshots for any file system or ZFS/Btrfs snapshots) but it does not offer anything directly to end users. The venerable built in NTBackup (afaik the only built in user backup system included in Windows) is better than nothing but is a far cry from Borg/Bup - it is practically infeasible to snapshot e.g. every hour.
