-------------------------------------

Hi Jan,

If you look at the patch most of the backup/restore work is being offloaded to the ReplicationHandler.
So to make the underlying storage pluggable we just need to make the changes there. The only
change required with respect to this patch is the backup of zk files.

> We should have an easy way to do backups and restores in SolrCloud. The ReplicationHandler
supports a backup command which can create snapshots of the index but that is too little.
> The command should be able to backup:
> # Snapshots of all indexes or indexes from the leader or the shards
> # Config set
> # Cluster state
> # Cluster properties
> # Aliases
> # Overseer work queue?
> A restore should be able to completely restore the cloud i.e. no manual steps required
other than bringing nodes back up or setting up a new cloud cluster.
> SOLR-5340 will be a part of this issue.
