Merging will probably be a process of loading indices and adding all documents from the backup indices to the live indices - however if you deleted anything, you might restore it without it being attached to a task (that can be tested as well, but more work...)
Hmmm I would guess something would be possible but I'm not sure how to go about it. Maybe @<1523701087100473344:profile|SuccessfulKoala55> or @<1523701994743664640:profile|AppetizingMouse58> can give some more input.
Hi @<1523701083040387072:profile|UnevenDolphin73> , all the scalars plots etc are saved on Elastic
@<1523701087100473344:profile|SuccessfulKoala55> could you provide some instructions?
Eek. Is there a way to merge a backup from elastic to current running server?
