-- 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.
--
-- You can create snapshots of volumes in a Region and volumes on an
-- Outpost. If you create a snapshot of a volume in a Region, the snapshot
-- must be stored in the same Region as the volume. If you create a
-- snapshot of a volume on an Outpost, the snapshot can be stored on the
-- same Outpost as the volume, or in the Region for that Outpost.
--
-- When a snapshot is created, any Amazon Web Services 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 might 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 @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.
--
-- You can tag your snapshots during creation. For more information, see
-- <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html Tag your Amazon EC2 resources>
-- in the /Amazon Elastic Compute Cloud User Guide/.
