How OKM Determines if a Backup Contains a Data Unit Key

A backup contains a data unit key if the backup occurred after creating the data unit key but before destroying the data unit key.

To account for the possible time discrepancies between KMAs, OKM uses a fixed five minute backup time window when comparing date-times. The backup time window minimizes falsely reporting that a data unit does not exist in a particular backup when in fact it does. Such a case is known as a "false negative" and seriously undermines compliance requirements for data destruction. Unlike "false negatives," "false positives" do not undermine compliance requirements for data destruction, hence the five minute window.
