It's good practice to periodically backup up your database. This functionality is coming to Amahi soon, but until then there is a simple way to automate it. This can be done using AutoMySQLBackup script.
Features
- Backup multiple MySQL databases with one script. (Now able to backup ALL databases on a server easily. no longer need to specify each database separately)
- Backup all databases to a single backup file or to a separate directory and file for each database.
- Automatically compress the backup files to save disk space using either gzip or bzip2 compression.
- Can backup remote MySQL servers to a central server.
- Runs automatically using cron or can be run manually.
- Can e-mail the backup log to any specified e-mail address instead of "root". (Great for hosted websites and databases).
- Can email the compressed database backup files to the specified email address.
- Can specify maximum size backup to email.
- Can be set to run PRE and POST backup commands.
- Choose which day of the week to run weekly backups.
What it does
- Every day it will run mysqldump and gzip will dump your specified databases to the /var/hda/files/dbbackup/daily directory, it will rotate daily backups weekly so you should never have more than 7 backups in there.
- Every Saturday it will again backup the databases you have chosen but they will be placed into /var/hda/files/dbbackup/weekly, these will be rotated every 5 weeks so there should never be more than 5 backups in there.
- Every 1st of the month it will create a backup of all databases and place them into /var/hda/files/dbbackup/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.
How to Install
In Ubuntu
| bash code
|
sudo apt-get install automysqlbackup
|
- edit the config file located at
| Text
|
/etc/default/automysqlbackup
|
| bash code
|
sudo nano /etc/default/automysqlbackup
|
- At the bare minimun, in the config file, edit the BACKUPDIR variable
- run automysqlbackup to see if it works (you should get backups added to your backupdir directory:
| bash code
|
sudo automysqlbackup
|
| bash code
|
sudo crontab -e
|
- add the following for running cron everyday at midnight
| Text
|
0 0 * * * /usr/sbin/automysqlbackup
|
Installing from project file
- Create a share called dbbackup.
- Download the script to /tmp directory.
| bash code
|
cd /tmp wget http://downloads.sourceforge.net/project/automysqlbackup/AutoMySQLBackup/AutoMySQLBackup%20VER%202.5/automysqlbackup-2.5.1-01.sh
|
- Some changes will need to be made for this to work on your HDA. As root user, update lines indicated in automysqlbackup-2.5.1-01.sh to read as follows:
| Text
|
Line 39: USERNAME=root Line 42: PASSWORD=hda Line 51: BACKUPDIR="/var/hda/files/dbbackup" Line 65: MAILADDR="root" Line 76: DBEXCLUDE="information_schema performance_schema mysql" Line 79: CREATE_DATABASE=yes Line 94: LATEST=yes
|
- Rename and copy the automysqlbackup-2.5.1-01.sh from /tmp to /usr/bin and set the permissions:
| bash code
|
cd /usr/bin cp /tmp/automysqlbackup-2.5.1-01.sh automysqlbackup chmod 755 automysqlbackup
|
- Set automysqlbackup as a daily cron job (Optional):
| bash code
|
cd /etc/cron.daily ln -s /usr/bin/automysqlbackup
|
Tips
- To change day of week (1=Monday thru 7=Sunday; defaults to 6=Saturday) for backup, update the number on the following line in automysqlbackup as root user:
| Text
|
Line 85: DOWEEKLY=6
|
- To run anytime, as root do the following:
| bash code
|
automysqlbackup
|
- This script is well documented. Options can be easily customized to meet your specific HDA requirements. The guidance can be found in the automysqlbackup, starting at line 110.
NOTE: When it's run the first time, it will create the directory structure automatically if it does not already exist.
