startWindowMinutes

A value in minutes after a backup is scheduled before a job will be canceled if it doesn't start successfully. This value is optional. If this value is included, it must be at least 60 minutes to avoid errors.

This parameter has a maximum value of 100 years (52,560,000 minutes).

During the start window, the backup job status remains in CREATED status until it has successfully begun or until the start window time has run out. If within the start window time Backup receives an error that allows the job to be retried, Backup will automatically retry to begin the job at least every 10 minutes until the backup successfully begins (the job status changes to RUNNING) or until the job status changes to EXPIRED (which is expected to occur when the start window time is over).
