Hrishikesh Gadre commented on SOLR-5750:
----------------------------------------
[~varunthacker] Thanks for the info. That make sense.
I am currently investigating Solr Backup/restore changes for HDFS. I found this
old email thread which discusses different approaches,
http://qnalist.com/questions/5433155/proper-way-to-backup-solr
I think we settled on "copying" behavior for portability reason. I think we
should make this a configurable behavior so that we can make the best use of
capabilities of underlying file-system. May be we introduce a higher level API
(may be at the Directory interface level) ?
Any thoughts?

> 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.
