Question:

MySQL Administrator> Backup Project. It is a great tool to allow you to select databases, and schedule it.

However my issue is:

Today got a few new websites (new database created) Tomorrow got a few more new websites (new databases created)

In this case, I have to always go into Backup Project> Select those remaining schema not in the backup list...

How to make it auto check for any new databases and include in the backup schedule list?

In other word, how to automate the backup of all the mysql databases (so that we don't need to worry when there's new databases created everyday).

Any way to make it happen?

I'm using Windows 2008 server, which is not sh friendly.


Best Answer:


The problem with the three answers posted so far is that they do not enable you to selectively restore the databases. This can be a real problem in all but a catastrophe.

Ideally, you should have a daily backup, with some history. It should be bulletproof (--force), it should be logged (>> ...log), it should be compressed (| gzip), it should keep separate copies of each database, and it should automatically pick up any databases that are added.

Consider, rather, a shell script like this:

#!/bin/bash
Host=server.domain.com
BDir=/home/backup/backup/mysql
Dump="/usr/bin/mysqldump --skip-extended-insert --force"
MySQL=/usr/bin/mysql
Today=$(date "+%a")
# Get a list of all databases
Databases=$(echo "SHOW DATABASES" | $MySQL -h $Host)
for db in $Databases; do
        date=`date`
        file="$BDir/$Host-$db-$Today.sql.gz"
        echo "Backing up '$db' from '$Host' on '$date' to: "
        echo "   $file"
        $Dump -h $Host $db | gzip > $file
done

Which is assuming that you have a file ~/.my.cnf (chmod 600), that has:

[client]
user = "BACKUP"
password = "SOMEPASS8342783492"

Make sure that whatever user you are using for BACKUP has this grant statement:

GRANT 
  SELECT, SHOW VIEW ON *.* 
  TO BACKUP@localhost 
  IDENTIFIED BY 'SOMEPASS8342783492';

So simply add this to a nightly cronjob, and you have a daily backup that rotates each 7 days week.

0 3 * * *   backup-mysql >> backup-mysql.log 2>> backup-mysql.log

The backup directory then contains:
