Robert Parker commented on SOLR-5750:
-------------------------------------
You should have the option of backing up/replicating a live searchable
collection on SolrCloud A to a live searchable collection across a WAN on
SolrCloud B, each with their own separate ZooKeeper ensemble. You should also
be able to rename the collection on the fly so that the live searchable
collection on SolrCloud A is called "collectionA" and its live updated
searchable replication copy is known as "collectionB" so as to allow a single
remote instance of SolrCloud to be multi-homed to act as a replication target
for multiple other Solr instances' collections, even if those collections
happen to have the same name on each of their source instances. Also, WAN
compression/optimization would be helpful as well.

> Key: SOLR-5750
> URL: https://issues.apache.org/jira/browse/SOLR-5750
> Project: Solr
> Issue Type: Sub-task
> Components: SolrCloud
> Reporter: Shalin Shekhar Mangar
> Fix For: 4.8, 5.0
>
>
> 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.
