Sorry Derek, I disagree. 100G over (for example) 2 years is 4GB/month. Easily manageable even at ADSL uplink speeds. Sure, it's going to take time to get your current collection up there, but once there, rsync will provide all you need for a minimal overhead, given that Xtra are touting 100GB/mo plans at the moment.
S3 costs pence. 100GB over a LAN is trivial - just leave it running overnight. My problems with external drives... 1. the small ones keep going through the washing machine. 2. the disk-based ones have a hard life. Although hdds can handle 10's ( 100's? ) of g when not in use, they are often unstable ( tall and thin ) and can fall off desks when in use, and tend to be left in cars on hot days / rucsacs on the backs of cyclists in the rain, etc. 3. You have to remember to plug / unplug / pick them up / offload the responsibility when you're off sick / etc... I see them as a high risk alternative not to be trusted that much. For me, a far lower risk alternative is to have a networked solution running from cron. As I'm sure I said before, I have a backup server hidden away onsite, and a remote server in Canada, which is what I use for a multilevel backup solution. I've just checked on prices: a 1TB USB external drive is about $175 ( you're future proofing, right? ). Overuse charges for an extra 100GB isn't going to be anything like that much.
