Subject [jira] [Commented] (SOLR-5750) Backup/Restore API for SolrCloud
Date Thu, 17 Mar 2016 22:26:34 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15200515#comment-15200515
] 

Hrishikesh Gadre commented on SOLR-5750:
----------------------------------------

[~varunthacker] Is it possible that when the backup command is sent, one of the shards (or
specifically the shard leader) is in "recovering" state ? If yes what happens with the current
implementation?

> 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.
