LOCKSS系统 (Lots of Copies Keep Stuff Safe)通过将Web发布的证书资料的多份拷贝缓存在分布式的地点来保存对这些资源的访问，使用缓存池系统来修复破损的信息并对信息进行保护。
LOCKSS (Lots of Copies Keep Stuff Safe), based at Stanford University Libraries, is an international community initiative that provides libraries with digital preservation tools and support so that they can easily and inexpensively collect and preserve their own copies of authorized e-content. LOCKSS, in its eleventh year, provides libraries with the open-source software and support to preserve today’s web-published materials for tomorrow’s readers while building their own collections and acquiring a copy of the assets they pay for, instead of simply leasing them.
