# Do daylight saving or time zone changes affect scheduled backups?

No. Scheduled times are kept as local clock times, so a backup set for 02:00 stays at 02:00 after the clocks change and when you travel to another time zone. It won't skip or double a run twice a year.

If the Mac is asleep or away at the scheduled time, it backs up once when it's next able.
