Backing up and restoring data
The procedures for backing up and restoring data are the same for DSE In-Memory data and on-disk data.
Use snapshots to manage backups and restores.
You can also use the OpsCenter Backup Service.
Always run nodetool cleanup before taking a snapshot for restore. Otherwise invalid replicas, that is replicas that have been superseded by new, valid replicas on newly added nodes can get copied to the target when they should not. This results in old data showing up on the target. |
