Data Protection

Data is protected on three levels. A volume is backed up to S3-compatible object storage as a chain of snapshots, 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.

Topic	Purpose
Backup and Recovery	Backing up a volume to S3-compatible object storage, and restoring it.
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.
