Hi Wael,

Have you considered backing up the source data instead? You can always 
re-index to re-create the Solr data.

Replication will certainly allow you to maintain a copy of the Solr 
data, either so you can handle more search traffic by load balancing 
between the two, or to provide a failover capability in the case of a 
server failure. But this isn't a backup in the traditional sense. You 
shouldn't consider Solr as your 'source of truth' unless for some reason 
it is impossible to re-index.

Perhaps if you could let us know why you think you need a backup we can 
suggest the best solution.
