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:
-
Run
nodetool drainto 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 -
Manually back up your data directories.
The default location for index files is
/var/lib/cassandra/data/solr.data.
