Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ text string

Required. Textual representation of the crontab. User can customize the backup frequency and the backup version time using the cron expression. The version time must be in UTC timzeone. The backup will contain an externally consistent copy of the database at the version time. Allowed frequencies are 12 hour, 1 day, 1 week and 1 month. Examples of valid cron specifications: * 0 2/12 * * * : every 12 hours at (2, 14) hours past midnight in UTC. * 0 2,14 * * * : every 12 hours at (2,14) hours past midnight in UTC. * 0 2 * * * : once a day at 2 past midnight in UTC. * 0 2 * * 0 : once a week every Sunday at 2 past midnight in UTC. * 0 2 8 * * : once a month on 8th day at 2 past midnight in UTC.
↳ time_zone string

Output only. The time zone of the times in CrontabSpec.text. Currently only UTC is supported.
↳ creation_window Google\Protobuf\Duration

Output only. Schedule backups will contain an externally consistent copy of the database at the version time specified in schedule_spec.cron_spec. However, Spanner may not initiate the creation of the scheduled backups at that version time. Spanner will initiate the creation of scheduled backups within the time window bounded by the version_time specified in schedule_spec.cron_spec and version_time + creation_window.

getText

Required. Textual representation of the crontab. User can customize the backup frequency and the backup version time using the cron expression. The version time must be in UTC timzeone.
