backup script

[stuaz]

hello all,

Currently I have a backup script which every night will write to a tape, and store the tape output to a log file.

In the same script it will then email out the log file to email address i specify.

However, also have (If any errors are encountered) that it writes these errors to a 'error log' file.

However, the problem I have is that when the backup fails - i.e no tape, it just emails a blank email (Which would of been the log file), is there anyway I can email error file (in the same email) or even better would be that if the backup failed, instead of using the log file it emails the error file.

Please see below for my current syntax (minus the variables):

rm /utils/tar.all.log
rm /utils/tar.all.error.log

cd $STARTDIR

tar cvf $TAPEDEVICE $DATESTAMP * 2>$TAPEERRORLOGFILE > $TAPELOGFILE

echo "Backup of X Server $STARTDIR finished" $NOW >> $DATESTAMP
tar tvf $TAPEDEVICE |mail -s "System backup of X Server $(date)" -c $C
USTOMEREMAIL $CUSTOMEREMAIL2 $MAIL
tar tvf $TAPEDEVICE >> $TAPELOGFILE

Check the return status after tar runs. If it's zero, the backup worked. If it's non-zero, then it (probably) failed.

tar cvf $TAPEDEVICE $DATESTAMP * 2>$TAPEERRORLOGFILE > $TAPELOGFILE
if [ $? = 0 ]
   then mail_log_file
   else mail_error_file
   fi

Thanks for your help.
This is how it looks at the moment, but i havent ran it yet as I am working remotely.

rm /utils/tar.all.log
rm /utils/tar.all.error.log

cd $STARTDIR

tar cvf $TAPEDEVICE $DATESTAMP * 2>$TAPEERRORLOGFILE > $TAPELOGFILE

if[$? =0]

mail -s "System backup of $CUSTOMER completed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $EMAIL >$TAPELOGFILE

else

mail -s "System backup of $CUSTOMER completed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $EMAIL > $TAPEERRORLOGFILE

fi

bash is a bit touchy when it comes to spaces so:

if[$? =0]

won't work. This will:

if [ $? = 0 ]

You also forgot the 'then' before the 1st mail.

Thanks, I noticed that after uploading it onto the forums!

rm /utils/tar.all.log
rm /utils/tar.all.error.log

cd $STARTDIR

tar cvf $TAPEDEVICE $DATESTAMP * 2>$TAPEERRORLOGFILE > $TAPELOGFILE

if [ $? = 0 ]
then

mail -s "System backup of $CUSTOMER completed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $VALEEMAIL >$TAPELOGFILE

else

mail -s "System backup of $CUSTOMER Failed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $VALEEMAIL > $TAPEERRORLOGFILE

fi

This is how it looks now, but when I run it I get a problem with the mail command saying it is expecting:

mail: option requires argument --c

One thing I see is your directing output from mail to the log files, not specifying the files as input. The '>' when it should be '<'.

if [ $? = 0 ]
then

mail -s "System backup of $CUSTOMER completed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $VALEEMAIL < $TAPELOGFILE

else

mail -s "System backup of $CUSTOMER Failed $(date)" -c $CUSTOMEREMAIL1 $CUSTOMEREMAIL2 $VALEEMAIL < $TAPEERRORLOGFILE

fi

thanks for pointing that out, but it still does the same error:

[root@centos utils]# ./diskspacecheck
mail: option requires an argument -- c
Usage: mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr ...
[- sendmail-options ...]
mail [-iInNv] -f [name]
mail [-iInNv] [-u user]
[root@centos utils]#

OK, didn't look too closely at the error message. Sounds like variables CUSTOMEREMAIL1, CUSTOMEREMAIL2, VALEEMAIL, aren't defined. You can see what the actual mail command looks like by running the script like this:

sh -vx ./diskspacecheck

Thanks that worked brilliantly

You were correct, it wasn't setting the variable for one of the email addresses. Doh!
