[SOLVED] Yet Another Backup Script for Community Version

[borngunners]

This is what I get after running the script:

diff Backup started at: 00:00
Setting date & version Marker into /opt/zimbra/DATE_VERSION.txt
Doing a hotsync of /opt/zimbra/ to /tmp/fakebackups/

Dar had a problem!
/etc/cron.daily/zmbak: line 127: mail: command not found


What am I missing in this script for the dar to have problem. Also, what is it about line 127: mail: command not found?

More tweaks..

I have the script send an email each night, and now that I fixed the uuencode problem by installing sharutils I was receiving a 1MB+ file listing attachment each morning. I never read these, and I could do without an extra 370MB of data being added to my mail server each year (admin mail is rarely deleted, bad but fact).

The following tweak adds an option to enable/disable the attachment of the XX_Zimbra_Backup_DD-Month-Year.LIST.txt.gz files. Please note that the filenames in the snippets have been changed as per my last post.

First, add an option in the config area of the script:

#--- Log Settings ---#
EMAIL="xxxxx@xxx.xxxxxxx.xxx"	# the address to send logs to
EMAILCC="xxx@xxxxx.xxx"		# another address to send to
LOG="/opt/zimbra_backup.log"	# log location
ATTACHLIST="no"			# attach backup file or not?

Then head to the section that generates the email (around line 770):

# Script Timer
    STOPTIME=(`date +%s`)
    RUNTIME=$(expr $STOPTIME - $STARTTIME)
    echo
    echo "::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::" 
    echo "Zimbra $TYPE backup ended at: `date +%H:%M`" 
    echo "Backup took $(date -d "1970-01-01 $RUNTIME sec" +%H:%M:%S) to complete" 
    echo "::::::::::::::::::::: cheers Osoffice for the script :::::::::::::::::"
	if [ "$ATTACHLIST" = "yes" ]
	then
	    (cat $LOG; $UUENCODE_BIN "$ARCHIVEDIR""$BACKUPWEEK"_"$BACKUPNAME"_"$BACKUPDATE"_LIST.txt.gz "$ARCHIVEDIR""$BACKUPWEEK"_"$BACKUPNAME"_"$BACKUPDATE"_LIST.txt.gz) \
    | mail -c $EMAILCC -s "Zimbra $TYPE Backup Log on $HOSTNAME" $EMAIL
	else
	    cat $LOG | mail -c $EMAILCC -s "Zimbra $TYPE Backup Log on $HOSTNAME" $EMAIL
	fi
	
}

The section of script that is throwing the error looks like this:

nice -19 $DAR_BIN -s $ARCHIVESIZE -z$COMPRESS......

The only way I can see 'nice' being sent an '-s' operator is if the content of the $DAR_BIN variable is null so the command becomes 'nice -19 -s'

Do you have DAR installed? ..what is the output of:

whereis dar | awk '{print $2}'

For the line 127 issue.. what do you get if you run the following command?

whereis mail | awk '{print $2}'

I suspect you don't have a dummy mta (e.g. mailx package) installed for the script's 'mail' commands to use. If you do, check $paths etc. for the root user to make sure it's found.

These are the response for the commands above:

root@zimbra:~# whereis dar | awk '{print $2}'
/usr/bin/dar

root@zimbra:~# whereis mail | awk '{print $2}'
/usr/bin/mail

I have installed a dummy mta and I still have an error with sending mail. Also, there is still a nice error after making the necessary changes you suggested above:

Dar had a problem!
mail: /usr/sbin/sendmail: No such file or directory
Can't send mail: sendmail process failed with error code 1
Unknown command: "sendmail="
Null message body; hope that's ok

[borngunners]

These are the output:

root@zimbra:~# whereis mail | awk '{print $2}'
/usr/bin/mail

root@zimbra:~# whereis dar | awk '{print $2}'
/usr/bin/dar

[chewitt]

what's the PATH statement for the root account?

[borngunners]

what do you mean?
I always use su to access the root account and cd /root.

this is what I found in there:
dead.letter:
To: admin@zimbra.my.account.com
Subject: Zimbra backup error on zimbra.my.account.com
Cc: borngunners@my.account.com

To: admin@zimbra.my.account.com
Subject: Zimbra backup error on zimbra.my.account.com
Cc: borngunners@my.account.com

[chewitt]

what's the permissions on the dar/mail binaries?

[chewitt]

can you also post the output of $PATH for root accessed via "su - root" not "su root" or sudo

[borngunners]

root@zimbra:/usr/bin# ls -l dar
-rwxr-xr-x 1 root root 252140 2007-09-19 07:04 dar
root@zimbra:/usr/bin# ls -l mail
-rwxr-xr-x 1 root root 80316 2007-10-24 05:20 mail
root@zimbra:/usr/bin#


root@zimbra:~# su - root
root@zimbra:~#
