When home users back up their computers, a lot don’t think about the fact that in some scenarios of data loss, those backups won’t do them any good — the scenarios which involve the loss of both their computer and their backups. (Think home fire, or burglary that involves taking the computer and the external hard disk that contains the backup.) For this reason, one tenet of most corporations’ backup plans is that an entire backup set exists off-site from the machines that are being backed up — safety through separation. There are hundreds of thousands of corporations who have the need to manage this process, so as a result, there’s a market of off-site storage providers that’s expanded and matured in a way that supports the importance of the data that’s being moved into storage. The big players have service agreements that stipulate the time frame in which customers can get their data, they provide reasonable guarantees for the safety of the data, and they put quite a bit of effort into meeting these guarantees.

In today’s day and age, home users are installing internet connections with more and more bandwidth, and this has opened up the potential that these users can actually back up their computers to some off-site location over the internet; unsurprisingly, a group of services has popped up to support this potential, services like .Mac, AT&T Online Vault, Mozy, and Carbonite, and even applications like JungleDisk and Amazon S3 which provide the infrastructure to allow users to take a more customized or do-it-yourself approach to online backups. As we’re talking about backups of people’s data, you’d think that these services would provide similar guarantees about the data’s availability and the services’ reliability, yes? Alas, that appears to be a false assumption. Ed Foster, everyone’s favorite griper, took a look at the end-user license agreements for a few of the online backup services back in mid-February, and he was pretty amazed to find that all the ones he investigated disclaimed pretty much any responsibility for the usability or availability of the backups, or even for the functionality of the services at all. (Granted, at least a few of the services he examined were provided for free — so in the end, you get what you pay for — but others are paid services.) That’s a real shame… but I’d imagine that it’s also an indication that there’s a real market niche waiting for the right company to come in and provide the right level of service.


I rarely back up as often as I should. I’m feeling guilty now just thinking about it.
