Volume snapshots capture the state of a volume at a specific point in time. Snapshots are stored in S3 and can be used to restore a volume to a previous state.
Create a snapshot
zwrm volumes snapshot create <volume-name>
| Flag | Type | Default | Description |
|---|
--app | string | from zwrm.toml | Application name |
--app-id | string | — | Application ID |
Example
zwrm volumes snapshot create data --app my-app
List snapshots
zwrm volumes snapshot list <volume-name>
| Flag | Type | Default | Description |

Delete a snapshot
zwrm volumes snapshot delete <snapshot-id>
Deleting a snapshot is permanent and cannot be undone.
Automatic snapshots
Enable scheduled snapshots for a volume:
zwrm volumes snapshot enable <volume-name>
zwrm volumes snapshot disable <volume-name>
--app and --app-id flags.
Restore a volume from a snapshot
