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.
