If an abnormal system termination occurs (including external terminations), CA VM:Backup restarts all currently running jobs when you reinitialize the system. If a job encounters a permanent tape I/O error, a job rollback occurs, and CA VM:Backup immediately resumes job processing.
If a job encounters an I/O error other than a permanent I/O error or a procedural error such as an operator ignoring a tape mount request, CA VM:Backup does not restart the job but instead places it on hold. A CA VM:Backup operator or system administrator must restart the job later using the RELEASE command.
The following list indicates how CA VM:Backup restarts jobs using the checkpoint data.
Last completed catalog
Last completed domain on last completed tape for each tape stream (CA VM:Backup might ask the operator to remount some tapes so that it can accurately reposition the tapes for restarting)
Last completed domain; restarts restores of incompletely restored domains from beginning of domain
Last domain from input tape that was successfully copied to output tapes
Last reinitialized tape
When restarted, all jobs appear as though they were never interrupted, with one exception. If CA VM:Backup restarts a backup, restore, or MPC job using restart recovery, file-level detail information for domains processed before the point where the job restarted is missing from all reports except the keyword data report.
