Since http://ietherpad.com is down and I was notified all data was lost, this ruined my day, since I was already planning for past few weeks to write a script that would do daily backups. There is bright future however. I am migrating to http://titanpad.com, wrote backup script in advance, and also managed to get some data from chrome cache. Here are the steps: on linux, figure out which history Index are you interested in: grep -R ietherpad ~/.chromium/Default/* open it: sqlite3 ~/.chromium/Default/HistoryIndex2011-11 find your page and retrieve data: select * from pages_content where c0url like %ietherpad%
