+  <pre>Starts creating a new Cloud Bigtable Backup.  The returned backup
+long-running operation can be used to
+track creation of the backup. The
+metadata field type is
+CreateBackupMetadata. The
+response field type is
+Backup, if successful. Cancelling the returned operation will stop the
+creation and delete the backup.
+
+Args:
+  parent: string, Required. This must be one of the clusters in the instance in which this
+table is located. The backup will be stored in this cluster. Values are
+of the form `projects/{project}/instances/{instance}/clusters/{cluster}`. (required)
+  body: object, The request body.
+    The object takes the form of:
+
+{ # A backup of a Cloud Bigtable table.
+  &quot;startTime&quot;: &quot;A String&quot;, # Output only. `start_time` is the time that the backup was started
+      # (i.e. approximately the time the
+      # CreateBackup request is received).  The

+  &quot;state&quot;: &quot;A String&quot;, # Output only. The current state of the backup.
+  &quot;sizeBytes&quot;: &quot;A String&quot;, # Output only. Size of the backup in bytes.

+      # granularity that must be at least 6 hours and at most 30 days
+      # from the time the request is received. Once the `expire_time`
+      # has passed, Cloud Bigtable will delete the backup and free the
+      # resources used by the backup.
+}
+
+  backupId: string, Required. The id of the backup to be created. The `backup_id` along with
+the parent `parent` are combined as {parent}/backups/{backup_id} to create

+  <pre>Lists Cloud Bigtable backups. Returns both completed and pending
+backups.
+
+Args:
+  parent: string, Required. The cluster to list backups from.  Values are of the
+form `projects/{project}/instances/{instance}/clusters/{cluster}`.
+Use `{cluster} = &#x27;-&#x27;` to list backups for all clusters in an instance,
+e.g., `projects/{project}/instances/{instance}/clusters/-`. (required)
+  pageSize: integer, Number of backups to be returned in the response. If 0 or
+less, defaults to the server&#x27;s maximum allowed page size.
+  pageToken: string, If non-empty, `page_token` should contain a
+next_page_token from a
+previous ListBackupsResponse to the same `parent` and with the same
+`filter`.
+  filter: string, A filter expression that filters backups listed in the response.
+The expression must specify the field name, a comparison operator,
+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
+&lt;, &gt;, &lt;=, &gt;=, !=, =, 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:&quot;exact&quot;` --&gt; The backup&#x27;s name is the string &quot;exact&quot;.
+  * `name:howl` --&gt; The backup&#x27;s name contains the string &quot;howl&quot;.
+  * `source_table:prod`
+         --&gt; The source_table&#x27;s name contains the string &quot;prod&quot;.
+  * `state:CREATING` --&gt; The backup is pending creation.
+  * `state:READY` --&gt; The backup is fully created and ready for use.
+  * `(name:howl) AND (start_time &lt; \&quot;2018-03-28T14:50:00Z\&quot;)`
+         --&gt; The backup name contains the string &quot;howl&quot; and start_time
+             of the backup is before 2018-03-28T14:50:00Z.
+  * `size_bytes &gt; 10000000000` --&gt; The backup&#x27;s size is greater than 10GB
+  orderBy: string, An expression for specifying the sort order of the results of the request.
+The string value should specify one or more fields in 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, &quot;start_time&quot;. The default sorting order is ascending.
+To specify descending order for the field, a suffix &quot; desc&quot; should
+be appended to the field name. For example, &quot;start_time desc&quot;.
+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.
