I'd like to use the backup command to create a backup of each shard
leader's index periodically. This is for disaster recovery in case our data
center goes offline.
We use SolrCloud leader/replica for day-to-day fault-tolerance and it works
The backup command (http://master_host:port/solr/replication?command=backup)
works just fine but it returns immediately while the actual backup creation
runs in the background on the shard leader.
Is there any way to know when the actual backup is complete? I need that
hook to then move the backup to another storage device outside of our data
center, e.g. S3.
What are others doing for this type of backup process?
Thanks in advance.
