Citations OAIS page 4-8, section 4.1.1.3 "The Disaster Recovery function provides a mechanism for duplicating the digital contents of the archive collection and storing the duplicate in a physically separate facility. This function is normally accomplished by copying the archive contents to some form of removable storage media (e.g., digital linear tape, compact disc), but may also be performed via hardware transport or network data transfers. The details of disaster recovery policies are specified by Administration."

Notes

Precondition is Receipt of AIP because there has to be something to back up. No trigger because this is ongoing.
