Hello, i have 3 client MAC computers were they are using a Qnap NAS to backup with time machine. however one of the users thinks it is a good idea to backup all 3 of their mac computers to one backup using time machine. the users want real time restore with time machine. my question is what is a good setup to use for time machine and a 8 bay Qnap NAS, we plan on adding 3 more drives to the NAS for backup support. looking for assistance with how to setup time machine on mac and use the NAS server on the LAN.
