Good to know you'll have a backup. Because of the HKMDB's niche nature (at least in comparison to IMDB), and Bob's tendency toward (to crib a Dennis Lee-ism here) "draconian measures", I've never been 100% convinced it will be around when I'm an old, old man, or that my reviews won't be subject to purging if I overstepped a line I didn't know existed, despite his repeated assurances over the years that that the site is not going away anytime soon (except for that one time, pre-Google-ads, when we were asked to pony up cash to keep it from going away sometime soon ).
I remember, at the time, feeling ill at ease with a guilt trip to spare a little. This request was made exempt for the top contributors and I rationed while my word count did not rival folks who seemingly submit daily I was still contributing meaningfully and often enough to sleep at night without giving the matter much deliberation.
Oddly enough, I have several reviews at both Amazon and IMDB that are not backed up on my computer, but I fear less for them because those sites are administered by many, many people, and have taken the steps necessary to dominate their specialities to such a degree that the only threat to their existence would be the ultimate demise of the internet itself (probably around the time we're all plugged into the Matrix anyways, so it will hardly matter by then ).
Another possibility would be if you were to pen a cogent review on Amazon castigating Thomas Weisser's specious Asian Cult Cinema that proved such an electronic opprobrium that they [Amazon] were forced to truncate it or remove it outright in fear of an abate in sales.
