Backing up data using OpsCenter
The Backup Service provides a simple interface for scheduling regular or one-off backups of all or specific keyspaces in a DataStax Enterprise (DSE) cluster, and for recovering data from the stored backups.
DataStax strongly recommends that organizations using DSE create a good backup and recovery plan using the Backup Service. Testing backup and restore operations on a non-production cluster is also recommended to ensure that the disaster recovery plan deployed for your organization actually works as intended.
The Backup Service was designed to manage enterprise-wide backup and restore operations for DSE clusters. While some administrators and operations staff believe that backups are not needed because of powerful and flexible replication capabilities in DSE, proper backup and restore procedures are still very important to implement for production clusters.
While replication does provide for copies of data to exist in multiple locations, datacenters, and cloud availability zones, all operations performed in a cluster are replicated, including operations that result in lost or incorrect data. For example, if a table is mistakenly dropped, if data is accidentally deleted, or if cluster data becomes corrupted, those adverse events will be replicated to all other copies of that data. In such cases, there is no way to recover the lost or uncorrupted data without a backup of the data.
