How do I back up my bookmark files?

GiveALink provides a variety of useful services not available elsewhere. One is a search engine which, given a URL, finds other Web pages that people bookmark together with it (i.e. similar Web pages). The search engine also supports keyword search and the results can be personalized based on the user's submitted bookmark files. In addition, users can view, organize, augment their bookmarks online, as well as download their bookmark files to several computers.
