Backing up DSE Search data directories

As a starting point, use these steps to create backups for DSE Search data directories. These steps apply when the backups are intended to restore a cluster with the same token layout, and the backups can be created in a rolling fashion.


For each node:

  1. Drain the node to ensure that the search indexes are in sync with their backing tables. This command forces a memtable flush that forces a Solr hard commit:

    nodetool drain
  2. Shut down the node.

  3. Manually back up your data directories. The default location for index files is /var/lib/cassandra/data/

  4. Restart the node.
