E3 Source Code



procedure Verify_Backup;
-- Verify that a tape backup is complete and recoverable.
-- This program mimics the backup recovery procedure, reading all
-- appropriate data, but does not actually restore the data.
-- Verify backup is appropriate for any R1000 backup: 9-track or 8MM tape,
-- full, primary or secondary backup. As with backup recovery, tape mount
-- requests are generated at the system console.
--
-- For a 9-track tape backup, tapes should be loaded in the following
-- order: Backup Index (Blue) tape first, then data tapes in sequence.
