A volume recovery point is a point in time at which all data of the
volume is consistent and from which you can create a snapshot. To get a
list of volume recovery point for cached volume gateway, use
ListVolumeRecoveryPoints.
In the CreateSnapshotFromVolumeRecoveryPoint
request, you identify the
volume by providing its Amazon Resource Name (ARN). You must also
provide a description for the snapshot. When the gateway takes a
snapshot of the specified volume, the snapshot and its description
appear in the AWS Storage Gateway console. In response, the gateway
returns you a snapshot ID. You can use this snapshot ID to check the
snapshot progress or later use it when you want to create a volume from
a snapshot.
To list or delete a snapshot, you must use the Amazon EC2 API. For more
information, see
DescribeSnapshots
or
DeleteSnapshot
in the Amazon Elastic Compute Cloud API Reference.
