The first file is saved fine, the database dump is not.

Any ideas?

This morning I started noticing errors on my web sites and eventually tracked that down to a lack of disk space. I then looked in the /tmp/ folder on the server and found about 200 backup.xxxx directories created by this script.

What could have caused this script to have gone haywire like that?? I deleted the cron job, recreated it and reset it to run at midnight and will see if it happens again but it does worry me somewhat. The same script works perfectly on my other 2 servers.

Is there some way to force this script to die and email me if it runs into an error of ANY sort ????

Any help or suggestions would be greatly appreciated.

I tried Shane’s suggestion above for removing older backup folders but all I get is “Directory not Empty” back from ncftp. Will have to experiment a bit more with this.

What I found is a nice addition for is to include the following command in your ftpbackup.sh script just below the line ### Other Stuff ###

Add the following:

### Backup DPKG Software List ###
dpkg –get-selections > /etc/installed-software-dpkg.log

Then you also have your list of all your installed applications and you can use that to restore them too as per this article: http://www.cyberciti.biz/tips/linux-get-list-installed-software-reinstallation-restore.html#comment-173345

In my case, I only wanted to keep backups around for 1 week. So every day, when this runs, it removes the backup from 7 days ago. This is very easy to accomplish. Just add this code Before the ### Dump backup using FTP ### line:

REMOVAL_DATE=$(date -d “1 week ago” +”%d-%m-%Y”)

Then add this right after you open NCFTP, like so:

ncftp -u”$FTPU” -p”$FTPP” $FTPS<<EOF
rmdir $FTPD/$REMOVAL_DATE

You can change "1 week ago" as needed. "1 day ago" or "1 month ago" or "3 months ago" etc etc etc are all fine.

ncftpput -E -u $FTPU -p $FTPP -m $FTPS $FTPD/$NOW $BACKUP/*

I had to use the -E option because I can’t use passive mode at this time. Remove -E if you can use passive mode.

I then modified the last portion of the script to include my text for when the backup failed. It looks like this

### Find out if ftp backup failed or not ###
if [ "$?" == "0" ]; then
 rm -rf $BACKUP
 T=/tmp/backup.good
 echo "Date: $(date)">$T
 echo "Hostname: $(hostname)" >>$T
 echo "" >>$T
 echo "This email is to inform you that the latest backup was a success" >>$T
 mail  -s "[host.example.com] - Backup Successful" "$EMAILID" $T
 echo "Hostname: $(hostname)" >>$T
 echo "" >>$T
 echo "This email is to inform you that the latest backup has failed" >>$T
 echo "" >>$T
 echo "Please investigate why the backup failed. The backup files are still available at $BACKUP" >>$T
 echo "" >>$T
 echo "Don't forget to delete this directory when done" >>$T
 mail  -s "[host.example.com] - Backup Failed" "$EMAILID" <$T
 rm -f $T
fi

When you are doing FULL backup, you must first delete $INCFILE

if [ "$DAY" == "$FULLBACKUP" ]; then
  FTPD="/home/vivek/full"
  FILE="fs-full-$NOW.tar.gz"
  rm $INCFILE
  tar -g $INCFILE -zcvf $BACKUP/$FILE $DIRS
else
  i=$(date +"%Hh%Mm%Ss")
  FILE="fs-i-$NOW-$i.tar.gz"
  tar -g $INCFILE -zcvf $BACKUP/$FILE $DIRS
fi
