Disaster Recovery

Control‑M/Tape recovery is performed using the most current Trace file and the last Media Database backup in three steps (see the following figure). First, a backup and restore utility (for example, ADDRSSU) is run to restore the Media Database. Then, the CTTrcv utility is run to roll forward all Trace file Updates since the last backup. The IOADIG and CTTBIX utilities are then run to rebuild the file structure and indexes.

Note: Run the IOADIG utility with the FUNC=W parameter and run the IOADBF index format utility, before rebuilding the index file.
