You can use the Database Manager GUI to create a snapshot.
Only one snapshot can exist at any one time. When you create a new snapshot, you overwrite any previous ones.
The database instance is in the operational state ADMIN.
We recommend that you activate overwrite mode for the log area in the log settings (see Changing the Log Settings).
...
1. Choose Instance ® Snapshot.

The snapshot is created.
