              #     and the value that you want to use for filtering. The value must be a
              #     string, a number, or a boolean. The comparison operator must be
              #     <, >, <=, >=, !=, =, or :. Colon ':' represents a HAS operator which is
              #     roughly synonymous with equality. Filter rules are case insensitive.
              #
              #     The fields eligible for filtering are:
              #
              #     * `name`
              #     * `source_table`
              #     * `state`
              #     * `start_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
              #     * `end_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
              #     * `expire_time` (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
              #     * `size_bytes`
              #
              #     To filter on multiple expressions, provide each separate expression within
              #     parentheses. By default, each expression is an AND expression. However,
              #     you can include AND, OR, and NOT expressions explicitly.
              #
              #     Some examples of using filters are:
              #
              #     * `name:"exact"` --> The backup's name is the string "exact".
              #     * `name:howl` --> The backup's name contains the string "howl".
              #     * `source_table:prod`
              #            --> The source_table's name contains the string "prod".
              #     * `state:CREATING` --> The backup is pending creation.
              #     * `state:READY` --> The backup is fully created and ready for use.
              #     * `(name:howl) AND (start_time < \"2018-03-28T14:50:00Z\")`
              #            --> The backup name contains the string "howl" and start_time
              #                of the backup is before 2018-03-28T14:50:00Z.
              #     * `size_bytes > 10000000000` --> The backup's size is greater than 10GB
              #   @param order_by [::String]
              #     An expression for specifying the sort order of the results of the request.
              #     The string value should specify one or more fields in
              #     {::Google::Cloud::Bigtable::Admin::V2::Backup Backup}. The full syntax is described at
              #     https://aip.dev/132#ordering.
              #
              #     Fields supported are:
              #
              #     * name
              #     * source_table
              #     * expire_time
              #     * start_time
              #     * end_time
              #     * size_bytes
              #     * state
              #
              #     For example, "start_time". The default sorting order is ascending.
              #     To specify descending order for the field, a suffix " desc" should
              #     be appended to the field name. For example, "start_time desc".
              #     Redundant space characters in the syntax are insigificant.
              #
              #     If order_by is empty, results will be sorted by `start_time` in descending
              #     order starting from the most recently created backup.
