There has to be some way for my neighbor and I to back each other up over our home wireless networks. We can both see each other's routers. My house would have to burn pretty hot to destroy a backup at his house.
There are any number of ways to do that, with or without putting the data over the Internet. Here's how I would do it, assuming a strong signal:
1. Buy a wireless external hard drive / NAS device. They're out there.
2. Configure said device to
my router and map same as a network drive.
3. Carry the drive to my neighbor along with a six-pack, and set it up in a convenient location.
4. Test the connection from my place to make sure it's stable.
5. Use my current backup software of choice to create encrypted backups, and store the key in multiple locations (some obscure location on my Web server, my gmail account, my parents' safe, a flash drive in my safe deposit box, etc.).
6. Send the backups to the drive on an automated basis.
I suppose this strategy could also be used if you had secure outbuildings on your own property that were within WiFi range, but still far enough away to be safe from house fires and so forth. It wouldn't help much in the event of a flood or forest fire, however. (But then again, neither would stashing the drive in your neighbor's house.)
It's a creative idea, though. It brings up other creative ideas that would involve the Internet and remove the geographic restrictions, but would introduce new concerns (such as bandwidth caps and dynamic IP addresses). I'm thinking about incorporating it into my Backup Nut site, more as a way to stimulate creative thinking about backup than for any other reason. Getting people to
think about backup is nine-tenths of the challenge. Blissful ignorance still prevails among many ordinary users.
I'm also considering it for my elderly parents. They use satellite Internet and would rapidly reach their cap if they did online backup because the only data they actually care about happens to be media files (mainly pictures and videos of the grandkids). But they do have an electrified shed that
I think would be within WiFi range. The problem is that it's unheated, and I wonder if any drive would operate in the extreme cold. Nonetheless, it's an idea that would get around the caps.
They do have a neighbor whose house is too far away for conventional WiFi, but that might just connect using exterior directional antennae (or other, shall we say, "novel" methods)... Buried coax is also an option...
See? You've got me thinking.
If bandwidth caps aren't a concern, however, then I find it hard to justify something like this when commercial online backup services are so inexpensive (or even free) nowadays. Nonetheless, it's good, creative thinking that could work very well in some cases.
