// Creates a backup of an existing Amazon FSx file system. Creating regular backups
// for your file system is a best practice, enabling you to restore a file system
// from a backup if an issue arises with the original file system. For Amazon FSx
// for Lustre file systems, you can create a backup only for file systems with the
// following configuration:
//
// * a Persistent deployment type
//
// * is not linked to a
// data respository.
//
// For more information about backing up Amazon FSx for Lustre
// file systems, see Working with FSx for Lustre backups
// (https://docs.aws.amazon.com/fsx/latest/LustreGuide/using-backups-fsx.html). For
// more information about backing up Amazon FSx for Windows file systems, see
// Working with FSx for Windows backups
// (https://docs.aws.amazon.com/fsx/latest/WindowsGuide/using-backups.html). If a
// backup with the specified client request token exists, and the parameters match,
// this operation returns the description of the existing backup. If a backup
// specified client request token exists, and the parameters don't match, this
// operation returns IncompatibleParameterError. If a backup with the specified
// client request token doesn't exist, CreateBackup does the following:
//
// * Creates
// a new Amazon FSx backup with an assigned ID, and an initial lifecycle state of
// CREATING.
//
// * Returns the description of the backup.
//
// By using the idempotent
// operation, you can retry a CreateBackup operation without the risk of creating
// an extra backup. This approach can be useful when an initial call fails in a way
// that makes it unclear whether a backup was created. If you use the same client
// request token and the initial call created a backup, the operation returns a
// successful result because all the parameters are the same. The CreateBackup
// operation returns while the backup's lifecycle state is still CREATING. You can
// check the backup creation status by calling the DescribeBackups operation, which
// returns the backup state along with other information.
