Backups & restore points · When backups run
How often do automatic backups run?
Short answer: At most every 30 minutes plugged in and every 2 hours on battery (longer while busy); the next version captures every change. Back up now runs any time.
An automatic set saves a new version after your files change — at most once every 30 minutes while your Mac is plugged in and once every 2 hours on battery, a little longer while your Mac is busy. Nothing is missed: every change made in between goes into the next version.
The card says when the next automatic backup can start. Back up now runs one any time you like.
