DESCRIPTION
    Creates a backup of a Cloud Spanner database.

EXAMPLES
    To create a backup asynchronously, run:

        $ gcloud spanner backups create BACKUP_ID --instance=INSTANCE_NAME \
            --database=DATABASE --expiration-date=2020-03-29T10:49:41Z \
            --async

    To create a backup synchronously, run:

            --database=DATABASE --retention-period=2w

POSITIONAL ARGUMENTS
     Backup resource - The Cloud Spanner backup to create. The arguments in
     this group can be used to specify the attributes of this resource. (NOTE)
     Some attributes are not given arguments in this group but can be set in
     other ways. To set the project attribute:
      ◆ provide the argument backup on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       BACKUP
          ID of the backup or fully qualified identifier for the backup. To set
          the backup attribute:
          ▸ provide the argument backup on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --instance=INSTANCE
          The Cloud Spanner instance for the backup. To set the instance
          attribute:
          ▸ provide the argument backup on the command line with a fully
            specified name;
          ▸ provide the argument --instance on the command line;
          ▸ set the property spanner/instance.

REQUIRED FLAGS
     --database=DATABASE
        ID of the database from which the backup will be created.

     Exactly one of these must be specified:

       --expiration-date=EXPIRATION_DATE
          Expiration time of the backup, must be at least 6 hours and at most
          30 days from the time the request is received. See $ gcloud topic
          datetimes for information on date/time formats.

       --retention-period=RETENTION_PERIOD
          Retention period of the backup relative from now, must be at least 6

        The backup will contain an externally consistent copy of the database
        at the timestamp specified by --version-time. If --version-time is not
        specified, the system will use the creation time of the backup.
