I have a late 2012 SSD iMac connected via WiFi to a new 3 TB Time Capsule backing up the new iMac. I still have my previous 1 TB 2010 iMac i7 which was connected wirelessly to a slightly older 2 TB Time Capsule which I took off line. The older iMac is getting it's WiFi signal now from the new 3 TB Time Capsule. My question is what are my options to make good use of the older Time Capsule and the 3 years of accumulated data with all the older backups of the 2010 iMac it has been making for 3 years? Options: 1. Setup Time Machine in the older iMac to start also using the new Time Capsule for backups and simply ignore the 3 years of previous data on the older Time Capsule? Thus, the new 3 TB Time Capsule would be backing up 2 iMacs. 2. Connect the older 2 TB Time Capsule directly to the older 2010 iMac i7 via wire and let it continue it's backups but turn the WiFi OFF on the older Time Capsule? If I did that what type of connection would I have to use? The older iMac only has USB 2.0 and Firewire 800 and an Ethernet Port and Mini Display Port. 3. Some better use of the older Time Capsule, after erasing it's data (which I hate to do) "just in case"? Should I simply use the older Time Capsule 2 TB simply as a NAS device? How would I set that up? The house is not wired for Ethernet.. I just have the Cable modem connected via Ethernet to the new 3 TB Time Capsule and am using it's WiFi signal for everything Apple I own...MacBook Pros, MacBook Air, iPhone, iPad, etc. I'm very open to suggestions. I even thought of having the house wired for Ethernet for more flexibility except I'm already getting Internet speeds of 50 down and 10 up via WiFi so the signal is excellent. I would like to implement a Synology NAS soon and am using Crash Plan in the background as well as making regular Carbon Copy Cloner backups of both primary iMacs to external SSD's and Firewire Drives. Suggestions please as to my options? Thanks.
