Refreshing the backup Solr indexes (optional)

This is an optional step before initiating a hot backup.

1. Trigger a Solr index backup using a JMX client.

   JConsole (MBeans tab -gt SkyVault/Schedule/DEFAULT/MonitoredCronTrigger/indexBackupTrigger/Operations - executeNow button)

2. After completing this operation, the solr4Backup directory contains an up-to-date cold copy of the Solr indexes, ready to be backed up.
