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 ;-)

NOW=”$(date +”%d-%m-%Y-%I-%M”)”

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..

# Store list of databases
DBS=”"

leave bank or can insert an option

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)?

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

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.

Anyway, Thanks ,
It works fine in crontab now .

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.
MYSQL="/usr/bin/mysql"
MYSQLDUMP="/usr/bin/mysqldump"
CHOWN="/bin/chown"
CHMOD="/bin/chmod"
GZIP="/bin/gzip"


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

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
..with…
$CHOWN -R root $DEST

This script is simple and easy to use. It works like a charm. Thanks :-)

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.

wget http://cyberciti.biz/download/bash_scripting/backup/mysql-backup.bash

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

Setup three variable as follows:

MyUSER=”root”
MyPASS=”SET-MYSQL-PASSWORD”
MyHOST=”napta”

3) Save script and exit shell prompt

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

5) Execute script
./mysql-backup.bash

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

If you have more questions feel free to reply back

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