I have 2 question :
I know that snapshot and restore is the best way to backup an elasticsearch cluster, but since my ES is running inside a docker container which have a named volume, is it possible to backup this volume without stopping my ES container ? (i.e. is hot backup supported on ES ? )
Is it possible to export (or download) the snapshot created in ES in order to store it somewhere else ? From what I saw, the snapshot seems to be stored in .dat file and maybe in the indices/ folder but is it possible to export it as a tar archive maybe ? And will it be a problem when I try to restore it ?
