/**
* Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createSnapshot(CreateSnapshotRequest) CreateSnapshot operation}.
* <p>
* Creates a snapshot of an EBS volume and stores it in Amazon S3. You
* can use snapshots for backups, to make copies of EBS volumes, and to
* save data before shutting down an instance.
* </p>
* <p>
* When a snapshot is created, any AWS Marketplace product codes that are
* associated with the source volume are propagated to the snapshot.
* </p>
* <p>
* You can take a snapshot of an attached volume that is in use. However,
* snapshots only capture data that has been written to your 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 systems on 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
* <code>pending</code> .
* </p>
* <p>
* To create a snapshot for EBS volumes that serve as root devices, you
* should stop the instance before taking the snapshot.
* </p>
* <p>
* 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.
* </p>
