Open Journal Systems supports the LOCKSS (Lots of Copies Keep Stuff Safe) system to ensure a secure and permanent archive for journal content. The LOCKSS Program is an open-source software tool, based at Stanford University Libraries. It provides libraries and publishers open-source digital preservation tools to preserve and provide access to persistent and authoritative digital content.

See LOCKSS   Publisher Manifest LOCKSS page.

We also use Vernadsky National Library of Ukraine to store the archive of our journal.
