Time Machine, Apple’s built-in file backup and recovery tool, is awesome… eventually. I say that because it’s sloooooowww. You can quickly speed-up Time Machine’s backup process by typing the following in the Terminal:
sudo sysctl debug.lowpri_throttle_enabled=0
Type in your password and hit return and you’re good-to-go.
Unfortunately, this trick won’t hold through a restart. To do that, you can follow Mac Kung Fu‘s advice on how to permanently speed-up Time Machine.
