Backing Up Cassandra Databases

You can perform a full or incremental backup of the Cassandra database, commit log or both.

Note

The Cassandra backups directory content is cleared after an incremental backup.

Before You Begin

  • If you want to perform incremental backups, you must enable incremental backups on all Cassandra nodes. Edit the Cassandra configuration file (cassandra.yaml) and set the incremental_backups parameter to true.

  • To have the Commvault software back up the user-defined types, on the gateway node, set the additional setting nCaptureCassandraTypes to 1.

For instructions about adding an additional settings from the CommCell Console, see Adding or Modifying Additional Settings from the CommCell Console.
