Applications with an approved persistent-storage allocation use a fixed-size volume mounted at /data. Keep durable application files there rather than in the container’s temporary filesystem.
Capacity and lifecycle
Storage requires a compatible storage agent and enough customer and cluster capacity. The fixed-volume model supports one application replica. Do not assume several replicas can safely share the volume.
Retained data continues to consume capacity. An authorized platform administrator reviews the separate purge action.
Backups and availability
A retained volume is not a backup. This storage model does not by itself provide replication, automatic cross-node failover or a restore service. Confirm the backup and recovery arrangements for your application.
Export data with an application-consistent procedure before a destructive change. Copying a database file while it is being written may not produce a usable backup.
