How to backup historical stats and restore them

Hi, every time we take a node out of our cluster we lose all historical stats. We would like to preserve this data, since it comes in handy.

I see the stat files located in: /opt/couchbase/var/lib/couchbase/mnesia

There seems to be a lot of stats_archiver* files. If I backup these files, can I just copy these files back over to a node when we add them back into the cluster? Will this work or is there a better way to preserve this data?


Still stuck on this issue. Trying to spend up some test servers, but we are running into some resource limitations. Any help would be much appreciated.
