How to capture fbackup return value

[Kelvin Yu]

Hi,

I am writing a crontab script to do fbackup and at the end I want to alert my pager if the fbackup is successful or else. My log did not show any return code. Did I miss anything?
fbackup command looks like the following
#fbackup -0 -v -g PMgraph -f /dev/rmt/0m I bkuplist -V bkupvolume >fbackup.log

Thanks & any help appreciated.

fbackup returns return value as,

0 upon normal completion,
1 if it is interrupted but
allowed to save its state for possible restart

2 if any error conditions prevent the session from completing

Collect return type as,
fbackup -0 -v -g PMgraph -f /dev/rmt/0m I bkuplist -V bkupvolume >fbackup.log
returnvalue=$?

see fbackup man page for RETURN VALUE part.

HTH.

Opps. You are piping fbackup output to bkuplist there.

we cannot get fbackup execution return there.
We will be getting only return code of bkuplist there.

what is bkuplist there? It is it a script there.

HTH.

Thanks for helping.

My typo error! The command should be
#fbackup -0 -v -g PMgraph -f /dev/rmt/0m -I bkuplist -V bkupvolume >fbackup.log

bkuplist is only capturing what I am backing up.

I think I can capture the return code by
putting
returnvalue=$?

Thanks.

Hi,

Is there a way to capture fbackup messages for example:
fbackup(1417): cannot open the dates file /var/adm/fbackupfiles/dates for reading
fbackup(1004): session begins on Thu Oct 21 12:11:30 2004
fbackup(3203): volume 1 has been used 2 time(s)
fbackup(3024): writing volume 1 to the output file /dev/rmt/0m
1: / 2
2: /syb_bkup 4
3: /syb_bkup/abc 1
fbackup(1005): run time: 31 seconds
fbackup(3055): total file blocks read for backup: 7
fbackup(3056): total blocks written to output file /dev/rmt/0m: 31

I would like to see those fbackup(xxxx) messages recorded in my log file. How?

Thanks,
Kelvin

We can monitory all fbackup output and error information to a log file then,

# Start script
script /tmp/fbackup.log

# Fbackup
fbackup -0 -v -g PMgraph -f /dev/rmt/0m -l bkuplist -V bkupvolume

# Return code
ret=$?

# Script command exit
exit

Else, you can tee command as,

fbackup -0 -v -g PMgraph -f /dev/rmt/0m -l bkuplist -V bkupvolume | tee fbackup.log

Or simply, you can use as,
fbackup -0 -v -g PMgraph -f /dev/rmt/0m -l bkuplist -V bkupvolume 1>fbackup.log 2>&1

1>fbackup.log 2>&1 redirects all STDOUT / STDERR mode informations to that fbackuplog file.

HTH.
