Enabling commitlog backups
Commitlog backups allow point-in-time restores.
Prerequisites
- You must use Java 7 when backing up commitlogs.
Commitlog backups allow you to restore your data to a particular point in time.
Commitlog backups are only available for the following versions of DataStax Enterprise:
- For DataStax Enterprise 3.2: 3.2.8 or greater
- For DataStax Enterprise 4.0: 4.0.5 or greater
- For DataStax Enterprise 4.5: 4.5.3 or greater
- 4.6 or greater
Enabling commitlog archiving modifies Cassandra's commitlog_archiving.properties configuration file.
OpsCenter automatically enables commitlog archiving on the new nodes when adding new nodes to a cluster using OpsCenter if commitlog archiving is enabled on the cluster. 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.
