LOCKSS 

Open Journal Systems supports the LOCKSS (Lots of Copies Keep Stuff Safe) system to ensure a secure and permanent archive for the journal. LOCKSS is open source software developed at Stanford University Library that enables libraries to preserve selected web journals by regularly polling registered journal websites for newly published content and archiving it. Each archive is continually validated against other library caches, and if content is found to be corrupted or lost, the other caches or the journal is used to restore it. 

Setting up LOCKSS support for Open Journal Systems does not need to take place until after publishing is fully underway, at which point follow these two steps:

Identify 6-10 libraries that will register and cache the journal. For example, turn to institutions where editors or Board members work and/or institutions already participating in LOCKSS. See the LOCKSS community.
