Backup script...Please help Urgent

[copperslim]

I have a backup script that runs every night. When backup finishes it emails me with the path of the backup log.

So the date of the file becomes the current backup log file.

thisprog=$(basename $0)
LOG="/tape/logs/$thisprog.$(date +%d%m%y).log"

I please need a script that will grep “failed” in the log file base on the current backup (+%d%m%y ) and mail me a message Backup failed when ever it reads failed in the log file? If there is no failed in the log file then it mails me with the message backup was successful.

It would be easier to initionally call the log backup.log do the grep then move backup.log to backup.date.log

a=`cat $LOG|grep fail|wc -l`

if [ $a != "0" ]
then
mail user
else
sleep 1
fi

This way you don't have any of the problems of first of month dates

LOG1="/tape/logs/$thisprog.$(date +%d%m%y).log"
LOG="backup.log"

a=`cat $LOG|grep fail|wc -l`

if [ $a = "0" ]
then
mailx -s "Backup failed" you@you.com
else
mailx -s "Backup OK" you@you.com
fi

mv $LOG $LOG1

Thanx mrn
I will try and advise tomorrow.

Would it pick the latest backup log file as the previous files are still kept on the directory.

 

[mrn]

If you want to keep the current log use cp instead of mv but make sure you use a single redirect > to over-write the log each day you would use >> to append.

eg

cat /etc/passwd > newfile
cat /etc/group > newfile

would over-write passwd info with group info

but

cat /etc/passwd >> newfile
cat /etc/group >> newfile

would add group info onto the end of the passwd info

mrn I copied it to a new folder but it hungs when it is sending the mail. I have to press ctrl D before the mail gets send.

The script amended.

LOG1="/tsis/logs/tape_backup.$(date +%d%m%y).log"
LOG="/home/burlal/lovette_backuptest.log"

cp $LOG1 $LOG

a=`cat $LOG|grep fail|wc -l`

if [ $a = "0" ]

then
mailx -s "Backup OK`hostname` " you@you.co.uk
else
mailx -s "Backup failed hostname` " you@you.co.uk
fi

#mv $LOG $LOG1

 

[jad]

change mailx lines to something like:

mailx -s &quot;Backup OK`hostname` &quot; you@you.co.uk < /dev/null

 

[mrn]

Maybe better

mailx -s "Backup OK`hostname` " you@you.co.uk > /dev/null

It worked when I used jad's.
This is the msg I get on the screen.

Null message body; hope that's ok.

Thanx Guys.

I will like to add a line in the message body which will reads

"please check backup log '/tmp/logs/tape_backup.$(date +%d%m%y).log' for more details."

 

[SamBones]

Why don't you do it like this...

cat ${LOG} | mailx -s "Backup failed on $(hostname) $(date)" you@you.com

...this way you not only get notified, but you have the log there in the email to look over.

Hope this helps.

I think it is best to have your backup script check the return code of the backup function.
Then email based on that.

Here is a script that I wrote a couple of years ago.
If you can not cut and paste it out, then email me at lonf@earthlink.net and I will email your directly.
Feel free to edit the script any way you see fit.
Make sure you edit the email address and server dir paths.
