But if you want to have 50+ USB chassis with hard drives to cycle your backup on then by all means. And if you purchase eggs in a sac you will see breakage as well. You keep putting forth this idea that hard drives should be moved around and plugged into something like they were tape cartridges. You really MUST expand your horizons.
No, you really need to look at a phone bill. Mine comes every month in a big box which includes frame-relay and a dozen T1s. All this off-site over-the-wire backup sounds great until you calculate the cost of the WAN connections - I could buy a new tape drive every month. Backing up corporate data over DSL or cable lines is not realistic, upstream speeds are not nearly good enough. You *might* be able to keep a remote SAN in sync at a reasonable cost (minimum disaster recovery distance is supposed to be something like 50 miles); but that will probably require at least a dedicated T1. But you still have to back THAT up - and backups mean you can go back, not just to the most recent copy, but back, as in "the end of 2006". Your going to need a hell of allot of online storage to pull that off. And you cannot just rsync everything, there is lots of date other than files, including Dits, mail stores, and relation databases.
