Long-Term Storage of Moderately Large Datasets?

hawkeyeMI writes "I have a small scientific services company, and we end up generating fairly large datasets (2-3 TB) for each customer. We don't have to ship all of that, but we do need to keep some compressed archives. The best I can come up with right now is to buy some large hard drives, use software RAID in linux to make a RAID5 set out of them, and store them in a safe deposit box. I feel like there must be a better way for a small business, but despite some research into Blu-ray, I've not been able to find a good, cost-effective alternative. A tape library would be impractical at the present time. What do you recommend?"

    LTO tape, properly stored, will outlast burned optical media and hard drives. Great stuff and designed specifically for what you're talking about.

      Couldn't agree more. A tape library (as in autochanger) might be out of your budget, but a simple tape drive wouldn't be too much -- say $5000 for an LTO4. Media is $50-$100 or so depending on where you shop. Seriously, you're not going to find a reasonable way of storing that much data anywhere else.

      BTW, if you're not a member of LOPSA, you may want to seriously consider it. Even if you're not a sysadmin, this is definitely a sysadmin-type question, and their mailing lists are second to none. It's an excellent resource.

    Because Amazon can be *expensive* compared to doing it yourself ($$$ for data in, $$$ for data out, $$$ for monthly storage). But heh, what do I know. I just manage the storage for one of the LHC detectors (5PB spinning disk, 17PB tape). Amazon is good when you've got VC money or have no IT folks.
