There are quite a few aspects to such software that factor in (at least for me). I know CrashPlan used quite a lot of memory (here it's sitting at ~500mb), but as long as it's not getting in my way I can live with that. The same goes for bandwidth and CPU usage, the most important thing really is that I do not notice it's running.
One thing I also want is some kind of "time machine" functionality. I do not want to risk a file being overwritten (either by accident or malware) and some simple backup tool simply duplicating that remotely. Ideally there should be some way to go back to how the file was a week or a month ago. Most of these tools seem to support this somehow.
Then there is the storage question. Many of them promise "unlimited" storage, but have some small print that allows them to weed out anyone who uses more than what they deem "regular use". This is one area where I like SpiderOak's approach -- they offer you a set amount of storage, and then don't have to care how many computers or NAS drives you attempt to backup. On the other hand their tiers are somewhat more expensive than the "unlimited" ones. Also, as mentioned, they sometimes run promotions where you can get an "unlimited" account from them as well, and that is where I got mine. I haven't backed up more than ~120gb currently so I have no idea at what point they might start to question your usage.
