Backups & restore points · Speed, progress and the first backup
Will backups slow down my Mac while I work?
Short answer: They're designed not to: backups match their speed to how busy your Mac is and stop when you need the machine. For less impact, schedule them overnight, set working hours, or limit upload speed.
They're designed not to. Storage Studio matches its backup speed to how busy your Mac is and stops entirely when you need the machine, picking up where it left off afterwards. Your work always comes first.
If you want even less impact: - Schedule big sets for the night with On a schedule. - Turn on Stay out of my working hours. - Set a ceiling with Limit upload speed. - Adjust how much of the Mac background work may use in Preferences → Performance.
