How rust save works?

Howdy, first thread so i hope this is making it in the propper section.

So i had a nasty issue of save not "saving" and we had a 30+ hour rollback.
What i wondered is how rust handles saves and what files contains what.

So UserPersistence.db i am guessing this is blueprints for all players? Possibly more?
And Storage.db i am guessing is the main source of stored data. This MUST be where buildings are located as this is the largest file for us.

Then we have the SAVE folder with "the world".
This is the only file we had missing "0.sav" and that was the issue in the rollback.

So what is contained in the save folder and how does it "fill" its save database?
It seems that it fills the 0.sav with the newest data, and then the old ones are just... not needed?
so its 0.sav newest, 1.sav newest before that, and so on?

Thus if i have a 1.sav file JUST before the rollback then i can restore the server?
This would be great information if any of you have indepth knowledge about this.


And thanks all plugin makers and oxide coders for there great work.
Greatly appreciated .

 

How does this work now? I notice that the save folder no longer is in use as of the latest Rust update. Is there even a way to roll back now? I need to roll back at least 6 hours before a random wipe took place.
