Backing up mysql data bases daily,weekly and monthly

I recently find a script that does automatic backup of mysql data bases daily, weekly and monthly bases.

Change the name of database e.g in this case is joomla
Default backup directory is /var/backup, you can change other if you like.

Script:See at bottom. Save the script as autobackupmysql, change permission to execute by
#chmod +x autobackupmysql

Test the script by executing it

Verify the backup at /var/backup, there will be three folders daily, weekly and monthly. Change directory to daily and folder name of your database name e.g joomla, you shall see your database there e.g joomla.

Move script to to /etc/cron.daily for autoexecution.

# Set the following variables to your system needs
# (Detailed instructions below variables)

# Username to access the MySQL server e.g. dbuser

# Username to access the MySQL server e.g. password

# Host name (or IP address) of MySQL server e.g localhost

# List of DBNAMES for Daily/Weekly Backup e.g. "DB1 DB2 DB3"

# Backup directory location e.g /backups

# Mail setup
# What would you like to be mailed to you?
# - log : send only log file
# - files : send log file and sql files as attachments (see docs)
# - stdout : will simply output the log to the screen if run manually.
# - quiet : Only send logs if an error occurs to the MAILADDR.

# Set the maximum allowed email size in k. (4000 = approx 5MB email [see docs])

# Email Address to send mail to? (

# ============================================================
# === ADVANCED OPTIONS ( Read the doc's below for details )===

# List of DBBNAMES for Monthly Backups.

# List of DBNAMES to EXLUCDE if DBNAMES are set to all (must be in " quotes)

# Include CREATE DATABASE in backup?

# Separate backup directory and file for each DB? (yes or no)

# Which day do you want weekly backups? (1 to 7 where 1 is Monday)

# Choose Compression type. (gzip or bzip2)

# Compress communications between backup server and MySQL server?

# Additionally keep a copy of the most recent backup in a seperate directory.

# The maximum size of the buffer for client/server communication. e.g. 16MB (maximum is 1GB)

# For connections to localhost. Sometimes the Unix socket file must be specified.

# Command to run before backups (uncomment to use)

# Command run after backups (uncomment to use)

# Options documantation
# Set USERNAME and PASSWORD of a user that has at least SELECT permission
# to ALL databases.
# Set the DBHOST option to the server you wish to backup, leave the
# default to backup "this server".(to backup multiple servers make
# copies of this file and set the options for that server)
# Put in the list of DBNAMES(Databases)to be backed up. If you would like
# to backup ALL DBs on the server set DBNAMES="all".(if set to "all" then
# any new DBs will automatically be backed up without needing to modify
# this backup script when a new DB is created).
# If the DB you want to backup has a space in the name replace the space
# with a % e.g. "data base" will become "data%base"
# NOTE: Spaces in DB names may not work correctly when SEPDIR=no.
# You can change the backup storage location from /backups to anything
# you like by using the BACKUPDIR setting..
# The MAILCONTENT and MAILADDR options and pretty self explanitory, use
# these to have the backup log mailed to you at any email address or multiple
# email addresses in a space seperated list.
# (If you set mail content to "log" you will require access to the "mail" program
# on your server. If you set this to "files" you will have to have mutt installed
# on your server. If you set it to "stdout" it will log to the screen if run from
# the console or to the cron job owner if run through cron. If you set it to "quiet"
# logs will only be mailed if there are errors reported. )
# MAXATTSIZE sets the largest allowed email attachments total (all backup files) you
# want the script to send. This is the size before it is encoded to be sent as an email
# so if your mail server will allow a maximum mail size of 5MB I would suggest setting
# MAXATTSIZE to be 25% smaller than that so a setting of 4000 would probably be fine.
# Finally copy to anywhere on your server and make sure
# to set executable permission. You can also copy the script to
# /etc/cron.daily to have it execute automatically every night or simply
# place a symlink in /etc/cron.daily to the file if you wish to keep it
# somwhere else.
# NOTE:On Debian copy the file with no extention for it to be run
# by cron e.g just name the file "automysqlbackup"
# Thats it..
# === Advanced options doc's ===
# The list of MDBNAMES is the DB's to be backed up only monthly. You should
# always include "mysql" in this list to backup your user/password
# information along with any other DBs that you only feel need to
# be backed up monthly. (if using a hosted server then you should
# probably remove "mysql" as your provider will be backing this up)
# NOTE: If DBNAMES="all" then MDBNAMES has no effect as all DBs will be backed
# up anyway.
# If you set DBNAMES="all" you can configure the option DBEXCLUDE. Other
# wise this option will not be used.
# This option can be used if you want to backup all dbs, but you want
# exclude some of them. (eg. a db is to big).
# Set CREATE_DATABASE to "yes" (the default) if you want your SQL-Dump to create
# a database with the same name as the original database when restoring.
# Saying "no" here will allow your to specify the database name you want to
# restore your dump into, making a copy of the database by using the dump
# created with automysqlbackup.
# NOTE: Not used if SEPDIR=no
# The SEPDIR option allows you to choose to have all DBs backed up to
# a single file (fast restore of entire server in case of crash) or to
# seperate directories for each DB (each DB can be restored seperately
# in case of single DB corruption or loss).
# To set the day of the week that you would like the weekly backup to happen
# set the DOWEEKLY setting, this can be a value from 1 to 7 where 1 is Monday,
# The default is 6 which means that weekly backups are done on a Saturday.
# COMP is used to choose the copmression used, options are gzip or bzip2.
# bzip2 will produce slightly smaller files but is more processor intensive so
# may take longer to complete.
# COMMCOMP is used to enable or diable mysql client to server compression, so
# it is useful to save bandwidth when backing up a remote MySQL server over
# the network.
# LATEST is to store an additional copy of the latest backup to a standard
# location so it can be downloaded bt thrid party scripts.
# If the DB's being backed up make use of large BLOB fields then you may need
# to increase the MAX_ALLOWED_PACKET setting, for example 16MB..
# When connecting to localhost as the DB server (DBHOST=localhost) sometimes
# the system can have issues locating the socket file.. This can now be set
# using the SOCKET parameter.. An example may be SOCKET=/private/tmp/mysql.sock
# Use PREBACKUP and POSTBACKUP to specify Per and Post backup commands
# or scripts to perform tasks either before or after the backup process.
# Backup Rotation..
# Daily Backups are rotated weekly..
# Weekly Backups are run by default on Saturday Morning when
# cron.daily scripts are run...Can be changed with DOWEEKLY setting..
# Weekly Backups are rotated on a 5 week cycle..
# Monthly Backups are run on the 1st of the month..
# Monthly Backups are NOT rotated automatically...
# It may be a good idea to copy Monthly backups offline or to another
# server..
# Please Note!!
# I take no resposibility for any data loss or corruption when using
# this script..
# This script will not help in the event of a hard drive crash. If a
# copy of the backup has not be stored offline or on another PC..
# You should copy your backups offline regularly for best protection.
# Happy backing up...
# Restoring
# Firstly you will need to uncompress the backup file.
# eg.
# gunzip file.gz (or bunzip2 file.bz2)
# Next you will need to use the mysql client to restore the DB from the
# sql file.
# eg.
# mysql --user=username --pass=password --host=dbserver database < /path/file.sql
# or
# mysql --user=username --pass=password --host=dbserver -e "source /path/file.sql" database
# NOTE: Make sure you use "<" and not ">" in the above command because
# you are piping the file.sql to mysql and not the other way around.
# Lets hope you never have to use this.. :)
