If your backup disk is connected to another computer, make sure the computer isn’t in sleep. If your backup disk is connected to a network, make sure your Mac and disk are still on the same network, the disk is turned on, and the network isn’t experiencing problems.

Try any of these suggestions if Time Machine can’t find your backup disk.
