Use the dashboard or the Backup tab to set up and run your backup.

You can use Time Machine to back up your Mac computers onto a USB hard drive that is 
connected to one of the router’s USB ports. You can access the connected USB hard drive 
from your Mac with a wired or wireless connection to your router.

NETGEAR recommends that you use a new USB HDD or format your old USB disk to do the 
Time Machine backup for the first time. Use a blank partition to prevent some issues during 
backup using Time Machine. The router supports GUID or MBR partitions.
