Yes, you will always be able to upgrade to a newer version without needing
to reindex. A multi node cluster backup simplest option is to backup each
node data location.

Regarding backup. Since I am using ES sort of as a noSQL database it will
not be possible to reindex from scratch after updates has been done to the
documents.
Is it guaranteed that it will always be possible to import an index to a
newer version of ES without need of reindexing it?Second question. How do you backup shards that are not on the local node?

Yes, assuming you have 1 replica, and 2 machines, you only need to copy
one machine over. And the restore process you mentioned is good.

Hello, I'm planning to use very nice script by Karussell
https://gist.github.com/**1074906 https://gist.github.com/1074906
for backing up my ES.
But I have a cluster of currently 2 machines running the ES.
I want to make sure, that this is enough to copy the files just from one
machine, because after flush they are the same on both server boxes.
And to restore, I just need to restore files on one machine, run ES, and
on another I'd just run empty ES server with my custom mappings, and the
second machine would pick the data up from the first.
Am I correct, or my assumption is mistaken?Thank you,
