The documentation for revision cleanup says
"A fresh generation is generated every time revision cleanup runs"
https://experienceleague.adobe.com/docs/experience-manager-64/deploying/deploying/revision-cleanup.h...
I understand what are revisions/versions for each modified node. But I am not clear on "generation".
What exactly is a "generation"? Is this a backup copy of all the nodes?
If so, that would explain it why e.g. 5TB content is taking up 10TB space.
