I have 4 mac mini's running on a small home network. One is running as a headless server, one as a headless machine to run windows, and two stand alone machines that have their own screens and keyboards. Right now every night the macs backup to a TC. I also have CCC and have it clone the macs to a 8TB external HD I have attached the mac I use as a server. The 8TB is partioned off so each mac gets its own drive on the external drive. Everything works well, and the CCC just saved my butt from a HD failure. I made an image from the back up to an external and was able to boot off of it. But I am still don't have a backup of the macs off site. My internet is too slow for an internet backup. I was toying with the idea of getting a second 8tb external and swapping them out once a week. Put one in, then keep one off site, but because the external drive has to be partitioned into a hard drive for each mac, I am not sure how that would work. Any suggestions?
