Resolve 15b8 - not saving project backups with collaboration

Hi all, I'm working in a collaborative project on a PostrgreSQL project database on my local network, and when I have collaboration enabled Resolve (15b7 and now b8) doesn't seem to save project backups. Is there something I'm missing here or is this an issue? What info can I provide to help address it?

Resolve 15b8
macOS 10.13.6
iMac 5K 4.2GHz 40GB RAM
Media on 10GbE NAS

Many thanks!

same here...
is there a way to let DR create backups of the collaborative projects?

No one?
pretty "exciting" to go collaborative without proper backups/versioning...
