No alarm triggered when backup tape is full
Post 302617569 by kimurayuki on Tuesday 3rd of April 2012 12:43:28 AM

Yes, the script is executing thru cron as follows:
# Backup /data directories into tape device
#==========================================
0 5 * * * /export/home/provadm/script/tape_backup.sh >/dev/null 2>&1
#
I was unable to find any cron logs from /var/log.
Can you advise me which directory can I look for cron logs?
Thanks

Yes, this used to be working fine a year ago.
I've tested filling up a tape with some dummy files which i created in the directory, till it reaches the capacity of the tape(72GB). However, there is no alarm triggered.
I use tar as the backup utility.
