AutoMySQLBackup Requirements

The AutoMySQLBackup script only requires mysqldump (A standard utility provided with the mysql client) and gzip or bzip2 for compression of the backup files.

If you would like to have the log emailed to you then you will need to have permission to execute the "mail" program. If you want the compressed backup files mailed to you then Mutt must be available on the server.
Finally you will need a bash shell and the standard system tools and utilities (all these requirements should be the default on most linux system.)

What AutoMySQLBackup does

Every day AutoMySQLBackup will run (if setup on /etc/cron.daily) and using mysqldump and gzip will dump your specified databases to the /backups/daily directory, it will rotate daily backups weekly so you should never have more than 7 backups in there..

Every Saturday AutoMySQLBackup will again backup the databases you have chosen but they will be placed into /backups/weekly, these will be rotated every 5 weeks so there should never be more than 5 backups in there..

Every 1st of the month AutoMySQLBackup will create a backup of all databases and place them into /backups/monthly. These will never be rotated so it will be up to you to do your own house keeping. I would suggest taking a copy of this offline every month or two so that if you have a hard drive failure you will be able to restore your database..

AutoMySQLBackup Installation

The install is as simple as editing a few variables in the AutoMySQLBackup file. The full setup is documented in the AutoMySQLBackup script file below the variables section..

Here is a quick minimum setup step by step..

1. Download automysqlbackup.sh and place it into your /etc/cron.daily directory or your home directory.

2. Edit (at least) the following lines :-
# Username to access the MySQL server e.g. dbuser
USERNAME=dbuser 输入你的数据库的管理员的名字

# Username to access the MySQL server e.g. password
PASSWORD=password 输入你的数据库管理员对应的密码

# List of DBNAMES for Daily/Weekly Backup e.g. "DB1 DB2 DB3"
DBNAMES="DB1 DB2 DB3"输入你要备份的数据库的名字，如果你要备份所有的数据库就输入all

# Backup directory location e.g /backups
BACKUPDIR="/backups" 根据你的情况输入数据库的备份的路径

3. Make the file executable :- chmod u+rwx

4. Create the following directory./backups 这个根据自己的情况决定是否创建

5. That's it.. Now you can run it using the command line "./automysqlbackup.sh" or if it is in /etc/cron.daily it will run each day when cron runs.
