I want to put the final touch on securing our data. We just had an amazing bullet-dodging experience[sup]*[/sup] and now both (PC and Mac) work off of a networked attached drive (a Linksys NAS200) with two WD drives configured as a RAID 1 array (or however it’s described). But that won’t help in the event of fire, lightning, theft etc.
I have an off-site backup account at MozyPro, which has great service and reasonable pricing for the relatively small amount (2-4 GB) of current work, but the two to three hundred or so GB of archival and other files we’d want in the event of a local catastrophe puts them beyond our budget (their business accounts run .50 per GB per month). But wait a second…
A sufficiently sized external drive is cheap. Couldn’t RhythmBrother and I just set up something similar to the off-site services? That is, backup software running independently on each of our machines that sends data to the drive attached to each other’s computer. It would have to be encrypted, as it’s going over the Internet, and would probably need some way to run a check on the foreign data’s integrity from time to time, but it seems like all of the necessary components already exist in some form or another.
Of course, both our houses can get flattened by a wild giraffe stampede at the same time, so nothing is absolutely perfect. But this setup (RAID1 with the off-site) seems about as secure as secure can get without going overboard. It also seems easier than manually running tape or other backups and shipping them to a secure location – it’s all automated.
Are there problems I’m overlooking? Is there software that does this?
[sup]*For the curious: We run an editorial/graphic design consultancy out of our home. The hard drive on the Mac had years of stored artwork and email. Maybe seventy percent of the art was backed up, but not the email or other data files. We finally got around to backing up everything… the day before the drive died.[/sup]
