Rollback World backup?

[Serpens]

Hi,

because of a mod bug, I lost my character.
But I found out I can get my character back, when I do a rollback (the map is not restored, but at least everything else).
 

But before I do the rollback, I would like to save the current world status, just in case the rollback undos to many things. So of which files do I have to do a backup first, to make sure I can get back to this status, if the rollback is not good?

If you're hosting single-level world, its save data (world data, including all players' data and your map) and are under Documents\Klei\DoNotStarveTogether\client_save\session\{sessionid} ({sessionid} is unique identifier of the world).

If you're hosting multi-level world (i.e. overworld+caves), its save data (world data and all players's data, excluding your map) are under Documents\Klei\DoNotStarveTogether\Cluster_{N}\{clustertype}\save\session\{sessionid} ({N} is the number of the save slot, {clustertype}  is Master or Caves). Your maps are still under Documents\Klei\DoNotStarveTogether\client_save\session\{sessionid} ({sessionid} is the same as either Master's or Cave's id).
