Manage a Backup Schedule

On this page

Warning:

As of May 10, 2022, CockroachDB v20.2 is no longer supported. For more details, refer to the Release Support Policy.

New in v20.2: You can create schedules in CockroachDB for periodic backups. Once a backup schedule is created, you can do the following:

Set up monitoring for the backup schedule
View scheduled backup details
View and control the backup schedule
View and control a backup initiated by a schedule
Restore from a scheduled backup

Create a new backup schedule

To create a new backup schedule, use the CREATE SCHEDULE FOR BACKUP statement. For example:

> CREATE SCHEDULE schedule_label
  FOR BACKUP INTO 's3://test/backups/test_schedule_1?AWS_ACCESS_KEY_ID=123&AWS_SECRET_ACCESS_KEY=123'
    WITH revision_history
    RECURRING '@daily'
    WITH SCHEDULE OPTIONS first_run = 'now';

In this example, a schedule labeled schedule_label is created to take daily (incremental) backups with revision history in AWS S3, with the first backup being taken now. A second schedule for weekly full backups is also created by default. Both schedules have the same label (i.e., schedule_label).

For more information about the different options available when creating a backup schedule, see CREATE SCHEDULE FOR BACKUP.

Set up monitoring for the backup schedule

We recommend that you monitor your backup schedule with Prometheus, and alert when there are anomalies such as backups that have failed or no backups succeeding over a certain amount of time— at which point, you can inspect schedules by running SHOW SCHEDULES.

Metrics for scheduled backups fall into two categories:

Backup schedule-specific metrics, aggregated across all schedules:
- schedules_BACKUP_started: A counter for the total number of backups started by a schedule
- schedules_BACKUP_succeeded: A counter for the number of backups started by a schedule that succeeded
- schedules_BACKUP_failed: A counter for the number of backups started by a schedule that failed
  
  When schedules_BACKUP_failed increments, run SHOW SCHEDULES to check which schedule is affected and to inspect the error in the status column.
Scheduler-specific metrics:
- schedules.round.reschedule-wait: The number of schedules that were rescheduled due to a currently running job. A value greater than 0 indicates that a previous backup was still running when a new scheduled backup was supposed to start. This corresponds to the on_previous_running=wait schedule option.
- schedules.round.reschedule-skip: The number of schedules that were skipped due to a currently running job. A value greater than 0 indicates that a previous backup was still running when a new scheduled backup was supposed to start. This corresponds to the on_previous_running=skip schedule option.

Note:

schedules.round.reschedule-wait and schedules.round.reschedule-skip are gauge metrics and can be graphed. A continual positive value for either of these metrics may indicate a misconfigured backup cadence, and you should consider adjusting the cadence to avoid waiting for or skipping the next backup.

For a tutorial on how to use Prometheus to set up monitoring and alerting, see Monitor CockroachDB with Prometheus.

View scheduled backup details

New in v20.2: When a backup is created by a schedule, it is stored within a collection of backups in the given location. To view details for a backup created by a schedule, you can use the following:

SHOW BACKUPS IN y statement to view a list of the full backup's subdirectories.
SHOW BACKUP x IN y statement to view a list of the full and incremental backups that are stored in a specific full backup's subdirectory.

For more details, see SHOW BACKUP.

View and control the backup schedule

Once a backup schedule is successfully created, you can view the schedule, pause the schedule, resume the schedule, or drop the schedule.

View the schedule

> SHOW SCHEDULES;

For more information, see SHOW SCHEDULES.

Pause the schedule

To pause a schedule, you can either specify the schedule's id:

> PAUSE SCHEDULE 589963390487363585;

Or nest a SELECT clause that retrieves id(s) inside the PAUSE SCHEDULES statement:

> PAUSE SCHEDULES SELECT id FROM [SHOW SCHEDULES] WHERE label = 'schedule_database';

For more information, see PAUSE SCHEDULES.

Resume the schedule

To resume a paused schedule, you can either specify the schedule's id:

> RESUME SCHEDULE 589963390487363585;

Or nest a SELECT clause that retrieves id(s) inside the RESUME SCHEDULES statement:

> RESUME SCHEDULES SELECT id FROM [SHOW SCHEDULES] WHERE label = 'schedule_database';

For more information, see RESUME SCHEDULES.

Drop the schedule

To drop a schedule, you can either specify the schedule's id:

> DROP SCHEDULE 589963390487363585;

Or nest a SELECT clause that retrieves id(s) inside the DROP SCHEDULES statement:

> DROP SCHEDULES SELECT id FROM [SHOW SCHEDULES] WHERE label = 'schedule_database';

For more information, see DROP SCHEDULES.

Warning:

DROP SCHEDULE does not cancel any in-progress jobs started by the schedule. Before you drop a schedule, cancel any in-progress jobs first, as you will not be able to look up the job ID once the schedule is dropped.

View and control a backup initiated by a schedule

After CockroachDB successfully initiates a scheduled backup, it registers the backup as a job. You can view, pause, resume, or cancel each individual backup job.

View the backup job

To view jobs for a specific backup schedule, use the schedule's id:

> SHOW JOBS FOR SCHEDULE 590204387299262465;

        job_id       | job_type |                                                                                                             description                                                                                   | statement | user_name | status  | running_status |             created              | started | finished |             modified             | fraction_completed | error | coordinator_id
