MySql backup script

This mysql database shell (bash download link at the end of script) script can be used:

1) To backup databases file /backup dir and later pick up by your script

2) You can skip few databases from backup!

Download script from above url.

Open file backup.bash.txt and customize it:
MyUSER=”YOUR-MYSQL-USER” # mysql username
MyHOST=”localhost” # mysql Hostname

Optional setup the name of database which you do not wish to backup:
IGGY="test db2 db3"

Rename backup.bash.txt file to mysqlbackup.bash and execute it as follows
$ ./mysqlbackup.bash

You may need to setup a cron job to take backup everyday.

    Thanks, just fixed URL.

    Great mysql backup script, a big thanks for it…

    I was thinking about it to write it myself but this is (almost) what i wanted.

  • Anonymous Dec 9, 2005 @ 12:12

    i am not getting how to use that script canu plz expalin . My user name in “root” hostname is napta

  • 🐧 nixcraft Dec 9, 2005 @ 13:36

    First download file at shell prompt (login as root user)


    2) Edit file in vi editor
    vi mysql-backup.bash

    Setup three variable as follows:


    3) Save script and exit shell prompt

    4) Setup execute permission
    chmod +x mysql-backup.bash

    5) Execute script

    6)In few mintues backup will be dumped in
    /backup/mysql directory

    If you have more questions feel free to reply back

    When running this script in cron, I get:

    Line 56: -u: command not found

    Line 56 is:
    DBS=”$($MYSQL -u $MyUSER -h $MyHOST -p$MyPASS -Bse ‘show databases’)”

    It works fine, when I run it by hand.

    Make sure variable MYSQL is pointing to correct mysql client

  • Jette Feb 25, 2007 @ 19:15

    Problem solved…

    When running the script in cron, you must replace the ‘which’ commands with the actual paths to chown, chmod, mysql etc…

    Tip to FreeBSD users:
    Replace this line…
    $CHOWN 0.0 -R $DESTT
    $CHOWN -R root $DEST

    This script is simple and easy to use. It works like a charm. Thanks 🙂

  • Jack Mar 12, 2007 @ 14:53

    when run in prompt works fine (./mysql-backup.bash)

    But why it does not work in crontab ?
    in /var/log/cron , the only message we have is “(root) CMD (mysql_backup.bash)

  • 🐧 nixCraft Mar 12, 2007 @ 17:28


    Setup correct PATH variable for cronjob and it should work. Or modify script and specify bin path as per your UNIX/BSD/Linux distro i.e.

  • Jack Mar 12, 2007 @ 20:57

    nixcraf ,
    I tried exactly as you wrote and it did not work.
    When I tried this (I have FreeBSD 6.x , mysql 4.x):

    Anyway, Thanks ,
    It works fine in crontab now .

    I really do appreciate the work but, please if you can help me to work on WinXP or from where I can find the backup script for windows operating system. Thanks in advance.

  • Marten Jun 30, 2007 @ 10:22

    the link to the script is broken.

  • 🐧 nixCraft Jun 30, 2007 @ 14:09


    I don’t see a problem; I can browse the link.

    Hello guys.

    I am looking up how to backup a table into a specified folder/file (my own path) of my remote server.
    The purpose is I want to change the db and tables CHARSET to UTF-8 automatically (this would be done by the installer script of the app I distribute).
    At this point, I came into this problem:
    mysql_query(“SELECT * FROM config INTO OUTFILE ‘./test.txt’ FIELDS TERMINATED BY ‘,’;”, $conn);
    I put the test.txt file into the php script directory, I CHMODed it to 777, but no luck. What am I missing?

    Is there a way to actually dump the database or each table into a specified folder (backup) of a script running on my server? (eg. public_html/script/db_backup/test.txt)?

    What is the

    # Store list of databases

    leave bank or can insert an option

    Hi Dear ,
    I am glad to find this script .
    Its working fine.
    But I have ome another problem regarding backup.
    I am dexcribing the problem below
    “I have to take backup of mysql table from remote machine and insert it into mylocal machine .”
    I have created one such script. Thats working as well.But there is still some problem regarding peformance of the script.

    If some-one reexecute the xcript it reinsert the data .
    which should not be done .
    I am pasting the code as well .
    Kindly suggest me the bugs and inhancement if there are any..


    $PING -c1 $host>/dev/null
    if [ “$?” != “0” ] ; then
    echo “source host unreachable”
    echo “going to take backup ”
    mysql -u ravi -h –password=shankar test -e ‘select * from usermst’ > /home/ravi/reg.txt
    if [ “$?” != “0” ] ; then
    echo “some error while taking backup so removing temprory file”
    rm /home/ravi/reg.txt
    echo “preparing to insert data”

    mysql -u root test -e ‘load data local infile “/home/ravi/reg.txt” into table usermst’
    if [ “$?” != “0” ] ; then
    echo “could not insert data so removing temporary file”
    rm /home/ravi/reg.txt
    echo “data has been inserted”
    rm /home/ravi/reg.txt
    echo temporary text file has been removed

    i fount this one very helpful. thanks a lot

  • China pictures Oct 24, 2008 @ 1:57

    I don’t want to write the password in the script, is there a way like with postgresql (pg_pass file), but with MySQL ?

  • Mark Apr 6, 2009 @ 15:52

    Thanks for the script, if you run this script more than once a day, i believe it overwrites itself. I changed line 75 to this so you can run it more than once a day:

    NOW=”$(date +”%d-%m-%Y-%I-%M”)”

  • Jul 27, 2009 @ 8:29


    better use
    NOW=”$(date +”%d-%m-%Y-%H-%M”)”

    because if you make backups on each hour you have 2009-07-27-10-00 twice a day 😉

  • Lucian Daniliuc Jun 12, 2011 @ 11:10

    Great script! Thanks a lot!

  • Ô±Õ¬Õ¥Ö„Õ½Õ¡Õ¶Õ¤Ö€ May 21, 2012 @ 10:35

    I must repeat Karo’s question:
    What is the

    # Store list of databases
    leave bank or can insert an option

    Also i include some dbs in iggy field

    IGGY=”test db2 db3″

    but script backups all databases of the server (even test and information_schema)

    How to fix it ?
