CPU & Memory automated back up problem

I am using HP UX 11.0

i want to make automated back up from SAM back up tool....

so i mentioned the file systems and back up device /dev/rmt/0m and time 0:00 and days of the week........

When you use SAM to setup a backup, it creates some files and set up a cronjob for you. Look in root's crontab to see if it got added. I just used SAM to setup a backup on HP-UX 11.0. The job is "/usr/sam/lbin/br_backup...." So was that job added to your root's crontab? Is cron running? My job says it will write logs to /var/sam/SAM_br_msgs so I would check that file. If the cronjob exists, it probably tried to run and wrote some error messages.

So the things to check are:

1) did SAM install a cron job?

2) does /var/adm/cron/log say if the job was attempted?

3) what errors are in the job's own logfile?

I believe that the path is /usr/lib/cron/log for the CRON execution log on HPUX 11.x.

I know it is a nit-picky item, but might save Prafulla some time.

Also, Prafulla, while in SAM I think you can view the SAM log after it executes your commands under OPTIONS --> VIEW SAM LOG. It has time parameters and other options you can set.

Now that I think about it, there is a much more reliable way to edit the crontab for root.

execute these commands.

crontab -l > tempcron
vi tempcron
crontab tempcron

This is easy and safe and you always have a copy of your CRON in case you accidentally blow it away.

No, /var/adm/cron/log is the correct path. It moved starting with hp-ux 10.x. However /usr/lib/cron is a symlink to /var/adm/cron for people who are used to the old path. HP does want us to start using the real path since the symlink may disappear in the future.

Thanks for the update. I was not aware of that change.

when i am trying to see the listing frm tape....

frecover -f /dev/rmt/0m -I /tmp/bkplog

it is showing the same one line 2048 0/


now if i don't want to make the backup by SAM tool wht i have to do make it run at a specified time?

i have to just edit crontab -e and put the timing in proper faomat....that's all...or i have to run any specific demon..
