None of these backup software programs we are discussing does true versioning. They all take snap shots where you can recover at the points in time a snapshot (scan) was made, but any other version is lost. At the moment versioning needs to be built into the tool, be it a word processor, photo editing, or video. If thats what you mean by anemic versioning then crashplan is not helping you. You could have gone through 10 versions by the time crashplan gets around to scanning the file

. CCC does snapshot versioning nicely in that it never throws anything away until you near the size limit of your drive, giving you time to clean up. Although it may take a bit more effort to find the version. Time machine is even more integrated, nicely taking snapshots hourly.
If none of your files are more than 6GB and you don't mind waiting weeks for the first backup to complete, crashplan may be good enough for you. But tomorrow, when crashplan goes belly up, what good is all that versioning? Its very risky to depend on it as your sole backup method, you must have an alternative. As Crashplan product support is quick to tell you, it is not suitable for more than the casual user, designed more to be affordable rather than provide extensive capability. There are several alternative providers for this type of service.
For the OP, timemachine built into the OS is the simplest backup to set up.
Time Machine does hourly snap shot versioning nicely and now that it can alternate backups between two or more drives, it is much more robust. You should stick with apple approved devices, a Time Capsule or AEBS with a separate drive for example. Many depend on time machine and have no issues, but most experts recommend having a backup of your backup for your most critical and unrecoverable data. As far as the iPad and iPhones, they can backup to a computer (or iCloud). The computer is then backed up.
Personally I've given up on crashplan and other ~real time on line solutions for now, they may be fine for others. In spite of the recent fiascos, there still are a lot of crashplan fanboys that are well satisfied. I use both timemachine to a networked Time Capsule alternating with a USB drive attached to the computer, and CCC to a standard NAS (synology) that is RAID0 mirrored for fault tolerance. But I am a belt and suspenders type of guy. Monthly I make a CC clone of everything really important to a couple hard drives and I stick them in my sister's basement. So I'm not completely out of the water should our house get destroyed. For those critical files that never change, I FTP them (encrypted) to my web server for safe keeping.
