Slashdot Mirror
Why Mirroring Is Not a Backup Solution
Craig writes "Journalspace.com has fallen and can't get up. The post on their site describes how their entire database was overwritten through either some inconceivable OS or application bug, or more likely a malicious act. Regardless of how the data was lost, their undoing appears to have been that they treated drive mirroring as a backup and have now paid the ultimate price for not having point-in-time backups of the data that was their business." The site had been in business since 2002 and had an Alexa page rank of 106,881. Quantcast said they had 14,000 monthly visitors recently. No word on how many thousands of bloggers' entire output has evaporated.
This is so ignorant that it must be a hoax.
Slashdot must be populated mostly by engineers and programmers that work on the software side of things, because nobody's considered mentioning a data recovery service, instead giving the "You're doooooooomed! You should have paid your IT people more" line. How very kind everyone here is of other people's technical mistakes. Because none of us have ever seen a bunch of dot files in a directory and typed "rm -rf .*" and then cried after or screwed up some production server with a "minor change"...

If you have lots of data, I don't see how tapes are really going to do the daily backup jobs.
More tape drives, idiot, and parallel backups. Mainframes and OpenVMS have been doing it that way for decades.

If it's only liberal bloggers content...

I hope you don't work anywhere near a datacenter.
You mistakenly believe that consumer grade drives have different MTBFs than OEM or 'enterprise' drives. What you're paying for is a vacation cruise for your sales rep.
I'm fully aware of differing needs for differing applications. I firmly believe all can be done with hard drives and even (in the future) SSD drives.
The availability systems I've engineered were through through, with audit and compliance and low MTTR in mine. It scales like crazy, and even more cost-effectively every month that hard drive costs go down-- and they do, every month since about 1988 in terms of cost per GB stored through a five year life cycle.
My decades of experience are unable to be exposed here. My years of battling the farce of overpriced, underperforming availability systems is the crux of my posts.
