Hi,
Its not possible for me to re-index the data in some of my indexes is only
saved in SOLR.
I need this solution to make sure that in case the live index fails, I can
move to the backup or replicated index.
OK, so now it's down to you to decide whether you want the backup index
immediately available for transparent failover, in which case Solr Cloud
is probably the way to go, or use what Emir recommends to regularly
create an offline backup you can restore from (bearing in mind this may
not be *totally* up to date in case of a failure and restoration may
take a while).

Hello,
Whats the best way to do a backup of the SOLR data.
I have a single node solr server and I want to always keep a copy of the
data I have.
Is replication an option for what I want ?
I would like to get some tutorials and papers if possible on the method
that should be used in case its backup or replication or anything else.
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.
Cheers
Charlie
