Delete the entire back up of my iMac to make space on my air port time capsule
Hi all. I have a 2 TB airport time capsule (via Time Machine) and originally had a single my iMac backing up to it. I have since added 2 laptops and the time capsule us quickly running out of storage. I plan on buying a large external hard drive and using that as my designated time machine back up for my iMac. I would like to continue to use the air port time capsule to back up my lap tops wirelessly.
My question is how do I delete the entire back up of the iMac from my air port time capsule to free up a large amount of storage? I can't seem to find a way to do this. I don't want to do it manually (file by file) but rather erase the entire back up of the iMac so that I have room to back up the laptops.
