To create backup data, you can add a snapshot of a volume. Snapshots are images of volumes at a specific point in time. Differential data from the original volume is stored in the pool when a snapshot is created. This section describes the workflows for creating a snapshot and restoring data. For details about snapshot-related functions, see the Hitachi Thin Image User Guide.
Schedule creating snapshots by using REST API. You can also manually create a snapshot by using the web-based user interface.
- When using the REST API:
- The following REST APIs can be executed to automate the operations:
- Creating a snapshot
- Getting snapshot information
- Getting information about a specific snapshot
- Restoring a snapshot
If you use the web-based user interface, the date and time when a snapshot was created are displayed based on the time zone set for the system of the management client. If you use the REST API, the data and time are returned based on Coordinated Universal Time (UTC).
