Backup your Solr

Imagine a scenario wherein your Solr crashed or met a disaster, and you don't have any backup with you; what will you do then? You might even lose your business. Tensed? Don't worry about it. Solr will handle it and get you out of such situations, you just need to top-up your efforts. In this section, you will learn how to backup our Solr based on various scenarios; for example, using Solr replication handlers and to back up your scripts from earlier Solr releases.

Using the Solr replication handler

The best and the easiest way to create backups in Solr is to use the replication handler. Before we take the concept forward let us first briefly look at index replication.

Index replication: It replicates master index to one or more slave servers, that is, the complete copies of a master index are being distributed to one or more slave servers. Moreover, all the querying is handled by the slave, and the master server keeps itself in track with the index updates.
