/**
* Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createSnapshot(CreateSnapshotRequest) CreateSnapshot operation}.
*
* Creates a snapshot of an Amazon EBS volume and stores it in Amazon S3.
* You can use snapshots for backups, to make copies of Amazon EBS
* volumes, and to save data before shutting down an instance.
*
*
* When a snapshot is created, any AWS Marketplace product codes that are
* associated with the source volume are propagated to the snapshot.
*
*
* You can take a snapshot of an attached volume that is in use. However,
* snapshots only capture data that has been written to your Amazon EBS
* volume at the time the snapshot command is issued; this may exclude
* any data that has been cached by any applications or the operating
* system. If you can pause any file writes to the volume long enough to
* take a snapshot, your snapshot should be complete. However, if you
* cannot pause all file writes to the volume, you should unmount the
* volume from within the instance, issue the snapshot command, and then
* remount the volume to ensure a consistent and complete snapshot. You
* may remount and use your volume while the snapshot status is
* pending .
*
*
* To create a snapshot for Amazon EBS volumes that serve as root
* devices, you should stop the instance before taking the snapshot.
*
*
* Snapshots that are taken from encrypted volumes are automatically
* encrypted. Volumes that are created from encrypted snapshots are also
* automatically encrypted. Your encrypted volumes and any associated
* snapshots always remain protected.
*
*
* For more information, see
* Amazon Elastic Block Store and Amazon EBS Encryption
* in the Amazon Elastic Compute Cloud User Guide .
