RHEL / CentOS Linux FTP Cron Job for automatic ftp backup

I need help with a cron job. A automatic ftp backup will pickup sql.tar.gz and upload to remote ftp server under CentOS Linux. How do I automate entire procedure to upload file /tmp/backup/sql.tar.gz?

You can use standard ftp client for File transfer protocol. The program allows a user to transfer files to and from a remote network site. However, modern FTP client follows little different syntax to upload file.

Here is a quick script to upload file:

# local directory to pickup *.tar.gz file
# remote server directory to upload backup
# login to remote server
ftp -n -i $SERVER <<EOF
mput $FILE/*.tar.gz

Make sure script has executable permissions:
$ chmod +x /path/to/ftp.backup.script.sh

Setup a cron job to run script at 15:30 (24 hr clock time) times:
30 15 * * * /path/to/ftp.backup.script.sh

Above script should work with all modern ftp client under any Linux / UNIX version.

A shell script to dump all mysql database and upload them via lftp program

Make sure you have lftp client installed:
# yum install lftp

### MySQL Server Login Info ###
# mysql server
### FTP SERVER Login info ###
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
GZIP="$(which gzip)"
NOW=$(date +"%d-%m-%Y")
[ ! -d $BAK ] && mkdir -p $BAK || /bin/rm -f $BAK/*
DBS="$($MYSQL -u $MUSER -h $MHOST -p$MPASS -Bse 'show databases')"
for db in $DBS
 FILE=$BAK/$db.$NOW-$(date +"%T").gz
lftp -u $FTPU,$FTPP -e "mkdir /mysql/$NOW;cd /mysql/$NOW; mput /backup/mysql/*; quit" $FTPS

Set a cron job:
# crontab -e
Run mysql backup ftp script everyday at midnight:
@midnight /path/to/mysql.backup.sh >/dev/null 2>&1

    I think this is not secure.

  • Wilfred February 24, 2008, 4:43 pm

    Where does it say it’s secure?
    It does the job, period.
    FTP itself isn’t secure

    Hey, this is very helpful. Thank for the script.

  • mcguillan November 25, 2008, 12:33 pm

    It would be better to encrypt at least the user and pass with md5…

  • Mrtz January 14, 2009, 5:53 am

    very useful, thanks.

    It is very helpful. Though have not tried it yet, I believe it will work like charm.

  • Jozef Sevcik January 24, 2009, 2:59 pm

    Thank you, it’s very helpful.

    One note, it’s useful to run ftp with ‘-i’ option also, so I use ‘ftp -ni’.
    It will disable confirmation at mput for all files and also enable you to transfer more all files you filter (*.tar.gz in article.)

    Thanks very much for the script, worked like a champ with minimal modifications needed.

    Hi the problem is mput line.
    if i give the full path its give 550 error which is seems permission related.
    I just then give the file name for example mput filename works for me.

    what is the problem with
    mput path/of/filename

  • Ekram October 22, 2009, 3:32 am

    one more thing i solve the permission problem but i think mput full path name not supported?
    please help me

    Ekram, try changing directory either befor you enter FTP or once in. That way, it will default to looking for your file in that directory. Don’t forget the / at the beginning of your path (/path/of/filename or //path/of/filename). Note: I am going over a secure network.

    # —– auto ftp DRAFT!!!
    cd /path/of/filename


    ftp -n $HOST <<END_SCRIPT
    quote USER $USER
    quote PASS $PASSWD
    put filename.txt /path/of/out_file/test_ftp.txt

    just a note that your cron cmd is wrong: crontab lines are minute, hour.

  • Jay October 20, 2011, 9:48 pm

    How can I get this to show the output from ftp so I can verify the file transferred correctly?

  • Sarah Hill December 29, 2011, 4:59 pm

    Wilfred, I disagree….Maytech is far more secure than most ftp file transfer services.
