Backing Up Photos / icloud
Hi
I have an old imac (approx 10 years old) on which nearly all of my photos (over 26000! in 271 events) are stored (on iphoto v 8.1.2). The operating system on the imac is OS X v10.7.5). I have just bought a new imac with retina display. The two imacs are coupled up to the same home network.
I would like to achieve the following:
1) Run an arrangement which ensures that all of my photos are backed up on an ongoing basis and all can be viewed on the new imac;
2) Not clog up the new imac hard disc with all these photos.
I would welcome any simple suggestions (As you will guess from the question I am rather a luddite, so any responses that minimize technical language will be particularly appreciated).
Many thanks in anticipation.
iMac, Mac OS X (10.7.5)
