I've thought that Amazon S3 would be an excellent backup media for a lot of businesses. But, they charged something like $0.10 USD per GB which just doesn't work when you are backing up a couple of TB of data on a regular basis. However, they have just changed their pricing model to eliminate the fee for data transfer in. You still pay to get data out ($0.12 USD per GB out), but that is (hopefully) much more rare if you are using it for backup.
I did a quick test this morning to move a XenServer VM snapshot to S3 using the free version of S3 Browser and it took 12 minutes to move 1.24 GB of data from our data center to S3. That is probably too slow to use for a TB of data (~200 hours assuming it is linear), but the pro version of S3 Browser will parallelize the upload and allow you to have more than 2 upload tasks at once. If it is 10x faster, then it becomes workable for a once-a-week archive.
