HTTP request


The URLs use gRPC Transcoding syntax.

Path parameters

Parameters
parent

string

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

Parameters
filter

string

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
  • backupSchedules

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
  • backupSchedules:daily - The backup is created from a schedule with "daily" in its name.
