-- Creates a snapshot of a block storage disk. You can use snapshots for
-- backups, to make copies of disks, and to save data before shutting down
-- a Lightsail instance.
--
-- You can take a snapshot of an attached disk that is in use; however,
-- snapshots only capture data that has been written to your disk 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 disk long enough to take a snapshot, your
-- snapshot should be complete. Nevertheless, if you cannot pause all file
-- writes to the disk, you should unmount the disk from within the
-- Lightsail instance, issue the create disk snapshot command, and then
-- remount the disk to ensure a consistent and complete snapshot. You may
-- remount and use your disk while the snapshot status is pending.
--
-- You can also use this operation to create a snapshot of an instance\'s
-- system volume. You might want to do this, for example, to recover data
-- from the system volume of a botched instance or to create a backup of
-- the system volume like you would for a block storage disk. To create a
-- snapshot of a system volume, just define the @instance name@ parameter
-- when issuing the snapshot command, and a snapshot of the defined
-- instance\'s system volume will be created. After the snapshot is
-- available, you can create a block storage disk from the snapshot and
-- attach it to a running instance to access the data on the disk.
--
-- The @create disk snapshot@ operation supports tag-based access control
-- via request tags. For more information, see the
-- <https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-controlling-access-using-tags Amazon Lightsail Developer Guide>.
