What is LOCKSS software? And what are Private LOCKSS Networks?

"Lots Of Copies Keep Stuff Safe." LOCKSS is the open source software that serves as the basis of the MetaArchive Cooperative's distributed preservation network infrastructure. LOCKSS stands for "Lots Of Copies Keep Stuff Safe." The LOCKSS software enables institutions to create, monitor, and maintain their own preservation services by 1) making copies of files and distributing them across multiple, geographically distinct sites; 2) constantly monitoring each file across those distributed servers for any change in status that may arise due to natural disasters, technical failures, or bit rot; and 3) repairing any damaged files within the overall network.

The MetaArchive Cooperative is only one of many Private LOCKSS Networks that are currently operating today. In each case, a group of likeminded institutions have come together to build their own preservation solution using LOCKSS. This differs significantly from buying into a vendor-based solution for digital preservation. As an open source software offering, LOCKSS makes it feasible for libraries and other cultural heritage institutions to maintain control over their own collections and to perform, not outsource, one of the core missions held by such institutions: that of preserving items of relevance to our cultural heritage.
