Deploy volume snapshot components
Volume Snapshot refers to the snapshot of a Persistent Volume (PV) at a specific point in time. If the cluster uses PVs that support snapshot functionality, the Volume Snapshot component can be deployed to enable the volume snapshot feature.
Currently, the platform only supports creating volume snapshots for PVCs that are dynamically created using StorageClasses. You can create new PVCs based on these snapshots.
Note: The supported access modes for creating PVC using snapshots are different from the supported access modes for creating PVC using StorageClasses. They are highlighted in bold in the table below.
| StorageClasses for creating volume snapshots | Single-node read-write (RWO) | Multi-node read-only (ROX) | Multi-node read-write (RWX) |
|---|---|---|---|
| TopoLVM | Supported | Not supported | Not supported |
| CephRBD Block Storage | Supported | Not supported | Not supported |
| CephFS File Storage | Supported | Supported | Supported |
