LOCKSS

LOCKSS — Lots Of Copies Keep Stuff Safe.

Evidence suggests that human factors (intentional and unintentional) are the greatest cause of loss or corruption to digital materials. Technology failures, economic failures and social failures all pose threats to the protection of digital content. When content is held in a single centralized repository, it is easy for people to tamper with a master copy without detection. A dark archive into which content disappears, only to reappear in a future emergency, does not engender confidence in either its availability or its correctness.
