Re: Stdout in script

I guess Tarsnap is exiting with an error and logging it to the stderr instead of stdout. And as you're not redirecting stderr to the file, the output is lost.
Does it help?

Hi all,

I try Tarsnap for some days now and it work perfectly.
He do what I tell it to do with the same simplicity of tar.

Actually, I've prepare a cron script to backup my system.
Echo to backup log (send to me by mail after backup) work great except for info about tarsnap stats.

Here a small extract of my script:

...
#Start Backup Data
echo "$(date +%H:%M) *1 Start Data Backup" >> ${backupdir}/backup.log
...
#Backup
${tarsnap} -c -f `hostname -s`-Data-${backupday} \
--print-stats \
${mysqldir} \
/usr/local/www \ >> ${backupdir}/backup.log
...
#Finish
if [ $?==0 ];then
echo "$(${date} +%H:%M) *2 Backup Finnish" >> ${backupdir}/backup.log
mail -s "TarSnap Backup Success" ${adminmail} < ${backupdir}/backup.log
else
echo "$(${date} +%H:%M) *2 Backup Failed" >> ${backupdir}/backup.log
mail -s "TarSnap Backup Failed" ${adminmail} < ${backupdir}/backup.log
exit
fi

But this is what I have in my mailbox

07:14 *1 Start Data Backup
07:18 *2 Backup Finnish

I don't know why *only* Tarsnap Stdout is not send to backup.log file
If I exec my script in shell, I saw stats normally -_-

Thanks
