# Can I limit how much bandwidth backups use?

Yes. In the set's **Change…** popover, open **Upload speed and Mac impact** and turn on **Limit upload speed**, then set a ceiling in MB/s. The limit is halved automatically while the Mac is on battery.

Even without a limit, Storage Studio matches its upload speed to how busy your Mac is and stops entirely when you need the machine. To change how much of your Mac background work may use in general, see **Preferences → Performance**.
