SolrCloud backup/restore
I've tested backup/restore successfully in a SolrCloud installation with a
single node (no replicas). This has been achieved in
https://issues.apache.org/jira/browse/SOLR-6637
Can you do something similar when more replicas are involved? What I'm
looking for is a restore command that will restore index in all replicas of
a collection.
Judging from the code in /ReplicationHandler.java/ and
https://issues.apache.org/jira/browse/SOLR-5750 I assume that more work
needs to be done to achieve this.
Is my understanding correct? If the situation is like this I guess an
alternative would be to just create a new collection, restore index and then
add replicas. (I'm using Solr 5.5.0)

Thank you both for the clarification and proposals!
This solrcloud_manager looks very promising. I'll try it out, the shared
filesystem requirement is no issue for me.

There is some automation around this process in the backup commands here:
https://github.com/whitepages/solrcloud_manager
It’s been tested with 5.4, and will restore arbitrary replication factors.
Ever assuming the shared filesystem for backups, of course.

Yes. It should be backing up each shard leader of collection. For each
collection, for each shard, find the leader and request a backup command on
that. Further, restore this on new collection, in its respective shard and
then go on adding new replica which will duly pull it from the newly added
shards.
