This document describes the considerations for setting up a system in which tape backups are executed automatically, and includes an example of how to do it.
You need to consider whether the system is rebooted each day, or runs continuously. Even if it runs continuously, you must include a method for the rescheduling of a task aborted by a shutdown. The example that follows is based on a system that runs continuously and reboots are permitted except for the time between midnight and 1:55 am. It uses the CCIBOOT.BAT file to invoke JOBMGR and to schedule another file, CCIBACK.BAT, that checks for the day of the week and schedules the file BACKUP.BAT for execution on the following day at 1:55 am. BACKUP.BAT is the batch file that calls ALL.BAT, which batch file that actually runs the backups of each drive using the FBACKUP.EXE program. BACKUP.BAT also makes an error log by sending the screen image of the console doing the backup to a file with TERMSET.

The status log that is created looks like this:
Tuesday
doing c
results 000
doing e
results 000
doing d
results 000
The "results 000" line refers to the errorlevel returned by the
tape backup software; if a problem had occurred, the errorlevel
environmental variable would be set to greater than 000.
