Medusa for Cassandra backup and restore
Medusa for Apache Cassandra® is deployed by K8ssandra as part of its Helm chart install.
If you haven’t already installed K8ssandra, see the install topics.
Even with the heightened availability of Apache Cassandra® a proper backup schedule and testing of restore procedures is good practice in case catastrophe strikes. With distributed systems backups can be tricky, there’s the timing of the snapshot process on all nodes, correlation of data files to remote storage, and eventual restore.
K8ssandra provides Helm charts for taking backups or triggering the restoration of data. This is accomplished via the Medusa for Apache Cassandra project from The Last Pickle and Spotify.
