Maintenance windows
One-time vs recurring
Different scheduling options.
Overview
The create form has a Repeat selector with three options: Don't repeat, Repeat daily, and Repeat weekly. Pick one based on whether the window is a one-off or a standing slot.
Don't repeat
Use for one-off events — a migration, a deploy, a hardware swap. The window runs at the scheduled start and closes at start + duration.
Repeat daily
The window advances by 24 hours after each run. Good for nightly backups or any job that runs every day at the same local time.
Repeat weekly
The window advances by 7 days after each run. Good for weekly patch windows or scheduled reboots.
Duration
Duration is stored as a number plus a unit (seconds, minutes, hours, days). Set it to the longest the maintenance can realistically take — alerts stay suppressed for the whole window.
