I have a Samsung external SSD on my new iMac. I detach the drive to also backup an older iMac to the same SSD. Would like to have Time Machine on the older iMac access the external drive on the new iMac and backup via my local LAN.
Each Mac should have its own Time Machine drive. When the drive dies that means you will lose backup to 2 computers which is penny wise and pound foolish.
Also, there is ZERO reason to use a SSD to backup, simply use an External Hard Disk which is more economical. Spending money on a SSD for backing up simply makes no sense. Kind of like using the Ferrari in the garage to go grocery shopping. Simply buy yourself a good quality External Hard Disk enclosure such as a OWC Mercury Elite Pro
