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.
Procedure
For each node:
-
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 -
Shut down the node.
-
Manually back up your data directories. The default location for index files is
/var/lib/cassandra/data/solr.data. -
Restart the node.
