All my work is backed up on an external hard drive. I tried plugging the hard drive directly into the time capsule but I can't see the disk in the time machine preferences. Am I doing the right thing? Thank you in advance for your help.
You will not see it if the TC cannot see it.. have you looked for it.
And that is the wrong place anyway.. to include it in the backup.. open the time machine preferences with the external drive plugged into the computer .. not the TC to include it, make sure it is not excluded.
Thanks for the response. I did try plugging the hard drive direcrlty into the mac and selecting it in the preferences but it says the contents of the hard drive is too big to back up. I then tried exclude some files but I keep getting this error message.
