Is there some way to validate a sysback tape? I'd hate to find out that the backup was no good, on the day of the system failure.
 
There's the smitty procedure (smitty verify_tape) which executes the listvgbackup -V -f /dev/mag_tape_device

This procedure only verifies if the system backup is valid.
The mksysb contained in a magtape is preceded by a bootable image, and a fake utoc
Try to read the mksysb script file to understand correctly the format and see how to validate also the bootable image... Perhaps the bootinfo -B /dev/mag_tape_device wuold give some info
