I've been using Hybir Backup for online + offline backup, which I found out about on HN. The application can backup to multiple locations, including their online service. So I have a local ioMega NAS plus the online backup service. They keep your data as long as you pay. Plus, Hybir does an image backup so you can use a boot CD to restore your HDD to the exact state it was in at the time of the backup. They de-dupe across all their clients so for online backup you only have to upload a small percent of your total data as much if (like Windows 7 files) will already be in their repository. I certainly feel a lot better about having BOTH an online backup and a local offline backup. I believe CrashPlan offers the same option, but without the image-style backup/restore.
