External Hard Drives

Can I use a 4TB external hard drive to back up three separate Macs, each having about 340gb stored on them?

If so, How do I keep them separate?

My hard drive seems to want to replace the first Mac's backup with the second's.

iMac, macOS 10.12

That being said, once each Mac has its own EHD with Time Machine (the belt), you can use the 4TB with 3 partitions to have an *additional* TM backup for each computer that you bring out every week or two. (The suspenders).


Or use the three partitions to maintain bootable clones using Carbon Copy Cloner or SuperDuper!.
