archive.today does that by rewriting the page to mostly static HTML at the time of capture.
archive.org indexes all URLs first-class and presents as close to what was originally served as possible. It also stores arbitrary binary files and captures JS and Flash interactivity with remarkable fidelity.
When logged in, the archive.org Save Page Now interface gains the options of taking a screenshot and non-recursively saving all linked pages. I cannot reason why—the more saved, the better, right?
In this case the less we know, the longer it will last. Notice how this site ignores robots.txt and copyright claims by litigious companies that would like to see their past erased.
The data saved on your NAS will outlast this site regardless of who owns/funds it.
Their explanation for ignoring robots makes sense - they say they ignore it because their crawler only runs when a human enters a URL and archives it, they also link to Google as this is what they do.
A site devoted to duplicating content from elsewhere online, and with a significant use-case of defeating paywalls, would be a very likely candidate for lawsuits.
Concealing ownership would tend to help avoid this / minimise consequences.
fwiw the website is only accessible by VPN in a lot of countries, which is say a lot for me..and i don't think they've taken down any content, although i cant say for sure.
• Share menu has buttons for Reddit, VKontakte, Twitter, Pinboard, and Livejournal. Eyebrow raising. VK is Russian, and so is LJ nowadays. Pinboard (notable as successor of del.icio.us) is American, coincidentally founded by a Polish immigrant.
• With a sizable dose of confirmation bias, the mistakes in the English of the site and blog do feel appropriately Slavic
this is why i like the archive.ph project so much and using it more as a kind of bookmarking service.
