Enabling commitlog backups
Commitlog backups facilitate point-in-time restores.
Commitlog backups facilitate restoring backup data to a particular point in time.
Commitlog backups are available for the following versions of DataStax Enterprise:
- For DataStax Enterprise 3.2: 3.2.8 or later
- For DataStax Enterprise 4.0: 4.0.5 or later
- For DataStax Enterprise 4.5: 4.5.3 or later
- 4.6 or later
Enabling commitlog archiving modifies the Cassandra commitlog_archiving.properties configuration file.
If commitlog archiving is enabled on a cluster, OpsCenter automatically enables commitlog archiving on the new nodes when adding new nodes to a cluster using OpsCenter. If you manually add nodes to a cluster and commitlog archiving is enabled, you must manually copy commitlog_archiving.properties to the new nodes prior to starting DataStax Enterprise.
Prerequisites
- You must use Java 7 or later when backing up commitlogs.
