Howto backup mysql stored functions and stored procedures

Hans-Henry Jakobsen — Mon, 02 Nov 2009 21:28:10 +0000

This is how you can backup you MySQL database(s) and stored procedures

# mysqldump --routines

Or you can backup only the stored procedures

# mysqldump --no-create-db --no-create-info --no-data --routines

Backup partition table

Hans-Henry Jakobsen — Thu, 19 Mar 2009 21:51:05 +0000

This post describes how you can backup your partition table for future recovery.

Backup

This example describes how you can backup the disk partition table on /dev/sda

dd if=/dev/sda of=sda.mbr bs=512 count=1

It’s also useful to keep a human readable copy of the disk layout for future reference

sudo fdisk -l > partitions.lst

Restore

This example shows how you can recover your file system using your partition table backup.

dd if=sda.mbr of=/dev/sda bs=512 count=1

This is a nice way to keep the information about your file system and will it help you in the future if you get disk corruption.
This does not only apply to linux partitions but all types of partitions.

Cold backup for the Open Source Edition of Zimbra

Hans-Henry Jakobsen — Thu, 31 Jan 2008 22:56:31 +0000

Today I’ve setup a cold backup routine to backup my Zimba installation running on my Debian (Etch) 4.0 server that is in full production now for my private domains. This is a slightly modified backup script for the Open Source Edition of Zimbra from the Zimbra Wiki. Please note that the script does a full backup every time it’s being run!

#!/bin/bash

# Zimbra Backup Script
# Requires sftp to run
# This script is intended to run from the crontab as root
# Free to use and free of any warranty!  Daniel W. Martin, 9 Sept 2007

# Live sync before stopping Zimbra to minimize sync time with the services down
# Comment out the following line if you want to try single cold-sync only
rsync -avHK --delete /opt/zimbra/ /backup/zimbra

# which is the same as: /opt/zimbra /backup
# Including --delete option gets rid of files in the dest folder that don't exist at the src
# this prevents logfile/extraneous bloat from building up overtime.

# Stop Zimbra Services
sudo -u zimbra /opt/zimbra/bin/zmcontrol stop
sleep 40

# Sync to backup directory
rsync -avHK --delete /opt/zimbra/ /backup/zimbra

# Restart Zimbra Services
sudo -u zimbra /opt/zimbra/bin/zmcontrol start

# Create a txt file in the backup directory that'll contain the current Zimbra
# server version. Handy for knowing what version of Zimbra a backup can be restored to.
sudo -u zimbra zmcontrol -v > /backup/zimbra/conf/zimbra_version.txt
# or examine your /opt/zimbra/.install_history

# Create archive of backed-up directory for offsite transfer
# cd /backup/zimbra
ZimbraVersion=zimbraBackup-zcs-5.0.1_GA_1902.DEBIAN4.0.20080109200914

tar -zcf /backup/$ZimbraVersion-$(date +"%Y-%m-%d").tgz -C /backup/zimbra .

# Transfer file to backup server using passwordless sftp
scp zimbraBackup-zcs-5.0.1_GA_1902.DEBIAN4.0.20080109200914-$(date +"%Y-%m-%d").tgz username@example.com:/path/to/backupfolder/

I’ve described passwordless ssh/sftp session in a earlier post so I won’t describe the last line of the backup script.

Backup mysql databases into separate files

Hans-Henry Jakobsen — Sun, 18 Nov 2007 21:07:39 +0000

This bach script makes separate backup files of all the databases in mysql and saves the result in the mysql_backup folder.

#!/bin/bash -v

USERNAME='yourusername'
PASSWORD='yourpassword'
HOSTNAME='yourhostname'
BackupFolder='/backup'

for i in $(echo 'SHOW DATABASES;' | mysql --user $USERNAME -p$PASSWORD -h $HOSTNAME | grep -v '^Database$' ); do
        mysqldump --user $USERNAME -p$PASSWORD -h $HOSTNAME --opt $i > $BackupFolder/$i.sql;
done;

Remember to change the -h, -p and -h switch according to your needs and avoid space between -p and the password variable.

    then
	for i in $IGGY
	do
	    [ "$db" == "$i" ] && skipdb=1 || :
	done
    fi

    if [ "$skipdb" == "-1" ] ; then
	FILE="$MBD/$db.$HOST.$NOW.gz"
	# do all inone job in pipe,
	# connect to mysql using mysqldump for select mysql database
	# and pipe it out to gz file in backup dir :)
        $MYSQLDUMP -u $MyUSER -h $MyHOST -p$MyPASS $db | $GZIP -9 > $FILE
    fi
