Subject [jira] [Commented] (SOLR-5750) Backup/Restore API for SolrCloud
Date Mon, 17 Mar 2014 15:33:43 GMT


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.

> 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.
