"The Internet Archive is hosting a public event on Thursday, Oct. 25, starting at 6:30 p.m. to officially mark the organization reaching an important milestone – 10 petabytes worth of digital material stored. That includes millions of digital books, music, movies and web pages.
The archive is supposed to be “Great Library of Alexandria, Version 2.” But Kahle is well aware that Version 1 couldn’t survive the foibles of humans.
“The history of libraries is they are burned,” he said. “That’s what will happen to us. We don’t know when. Hopefully, it is centuries from now.”
So the archive is fully backed up on servers in Redwood City, with partial copies in Amsterdam and — appropriately enough – Alexandria, Egypt."
