Offsite backup of some type is essential, in addition to external drives, disks [I burn blu-rays now] and/or some combination thereof.
Let me relate my experience with Carbonite, tho. My initial b/u of maybe 500GB of data took something like 6 months. Recovering that data in the event of a disaster might not take that long, but was extremely slow when I tried it. After that the service seemed OK until I upgraded my 2007 Mac Pro to a loaded up iMac this year. A few months later I got this perky email from Carbonite saying that my 50GB of data were all backed up now, isn't it wonderful? Their tech support dude that I talked to said basically, sorry about that, but they have no way to recognize your new computer, even though all your account info is unchanged, and all that data is unrecoverable. None of my complaints to Carbonite on this matter were ever answered.
I now use DropBox to b/u 100Gb of my newest stuff [which takes maybe 3 days]. YMMV
