Method: projects.instances.backups.list

Lists completed and pending backups. Backups returned are ordered by createTime in descending order, starting from the most recent createTime.

HTTP request


The URL uses gRPC Transcoding syntax.

Path parameters



Required. The instance to list backups from. Values are of the form projects/<project>/instances/<instance>.

Authorization requires the following IAM permission on the specified resource parent:

  • spanner.backups.list

Query parameters



An expression that filters the list of returned backups.

A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: <, >, <=, >=, !=, =, or :. Colon : is the contains operator. Filter rules are not case sensitive.

The following fields in the Backup are eligible for filtering:

  • name
  • database
  • state
  • createTime (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
  • expireTime (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
  • versionTime (and values are of the format YYYY-MM-DDTHH:MM:SSZ)
  • sizeBytes

You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic, but you can specify AND, OR, and NOT logic explicitly.

Here are a few examples:

  • name:Howl - The backup's name contains the string "howl".
  • database:prod - The database'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 (createTime < \"2018-03-28T14:50:00Z\") - The backup name contains the string "howl" and createTime of the backup is before 2018-03-28T14:50:00Z.
  • expireTime < \"2018-03-28T14:50:00Z\" - The backup expireTime is before 2018-03-28T14:50:00Z.
  • sizeBytes > 10000000000 - The backup's size is greater than 10GB


Number of backups to be returned in the response. If 0 or less, defaults to the server's maximum allowed page size.



If non-empty, pageToken should contain a nextPageToken from a previous ListBackupsResponse to the same parent and with the same filter.

Response body

If successful, the response body contains data with the following structure:

JSON representation
  "backups": [
      object (Backup)
  "nextPageToken": string

object (Backup)

The list of matching backups. Backups returned are ordered by createTime in descending order, starting from the most recent createTime.



nextPageToken can be sent in a subsequent backups.list call to fetch more of the matching backups.
