Data Protection

Data is protected on three levels. A volume is backed up to S3-compatible object storage by a StorageBackupPolicy, and it is replicated to a second cluster for a controlled failover. The state of the control plane itself lives in FoundationDB and is backed up separately, since a cluster cannot be rebuilt from its volumes alone.

The pages in this section protect volumes and the control plane of one simplyblock deployment. Protecting whole applications (their volumes together with their Kubernetes objects) across sites, with planned and unplanned failover, is the subject of Disaster Recovery.

Topic	Purpose
Backup and Recovery	Backing up volumes to S3-compatible object storage, and restoring them.
Asynchronous Replication	Replicating volumes to a second cluster, with controlled failover and failback.
FoundationDB Backup and Restore	Backing up and restoring the control plane state held in FoundationDB.
