New to AIX.
We perform backups of the AIX rootvg using SYSBAKP comand and writes data to the rmt1 tape, data on the user VG is backed up using cpio to same tape.
SYSBAKP is run manually at 5:00 pm the cpio backup is run on cron at 11:00 pm to same tape.
Post cpio backup using listvgbackup to query tape I can see the SYSBAKP contents. Using cpio -itvcC1 < /dev/rmt1 I can see the table of contents for the cpio backup.
How can I be positive that cpio has not written over the top of SYSBAKP data on same tape?
Thanks in advance.
