Agreed about Carbonite on the Mac, they were no help
in resolving this, not implemented correctly.
Carbonite is terrible on the Mac, fine on my PC. It gets hung up with no warning and I bailed out on it.
On my new Mac, I've switched to CrashPlan and it is working great. Very comparable in price and features. Highly recommended.
Also much more flexible in terms of configuration
Keep this in mind, people forget...you backup is only
as good as your capability to restore successfully.
You need to test from time to time you can get at your
files if needed. I would not trust or use any online
storage "gimick" from Verizon/Dell/Cisco, etc. They
might be OK, but stick with something in the mainstream
that gives a company reason to support it.
