What setup would you advise?
Here's what I've been exploring; I haven't constructed such a system, but am wondering where the holes would be. Can you poke some holes in this proposal and let me know?
- Two laptops, each running Windows 7, each with 500GB hard disks. Perhaps
something in this range.
- Something along the lines of the Verizon MiFi for reliable broadband connectivity (at least throughout North America)
- Something along the lines of the Cisco Valet or the Airport Express for setting up a small internal network for file-sharing purposes.
- Something like Mozy for reliable cloud-based backup, though I'm a little worried that the cloud-based backup schemes can't scale to dozens or hundreds of gigabytes.
- To augment the cloud-based backup strategy, a couple of these stocking stuffers can be used for local standby backup purposes.
With this gear, I think you can quickly set up a small internal LAN for file-sharing support between the two laptops, and each laptop can get online at will via the MiFi.
The primary laptop, which holds the master copy of all the files, can share that folder with the secondary laptop, and I think Windows 7 file sharing is robust and reliable enough that the other secondary can continue accessing those files even while the "primary" laptop is busy running large computations (or playing the occasional game of Dark Lords of Elven Magic V).
The secondary laptop is over-provisioned, but this is intentional, so that if the primary laptop fails, the secondary can take over the primary's duties (after restoring the data from a combination of the local spare backup and the Mozy data from the cloud).
Am I crazy?
