AutoMysqlBackup

Automysqlbackup

AutoMySQLBackup associates with DB configuration will create Daily, Weekly and Monthly backups of your MySQL databases. At least there is no panel in the server-manager but the configuration is quite simple with few commands listed above, handle by "config setprop automysqlbackup". I'm fairly sure that you do not have to modify huge options except the mail where logs and files are sent. With this contribs you save your mysql databases in a simple way.

Other Features include:

• Email notification of backups
• Databases split and sent by mails
• Backup Compression and Encryption
• Configurable backup rotation (no db command yet, you have to do it manualy)
• Incremental database backups (no db command yet, you have to do it manualy)

Installation

For SME8

This contrib is in the stephdl, you have to enable it before to install the contrib

db yum_repositories set stephdl repository \
BaseURL http://mirror.de-labrusse.fr/smeserver/\$releasever \
EnableGroups no GPGCheck yes \
Name "Mirror de Labrusse" \
GPGKey http://mirror.de-labrusse.fr/RPM-GPG-KEY \
Visible yes status disabled

After adding it to the database updating the configuration file is required:

signal-event yum-modify

yum install --enablerepo=stephdl smeserver-automysqlbackup
config set UnsavedChanges no

For SME9

yum install --enablerepo=smecontribs smeserver-automysqlbackup
config set UnsavedChanges no

You can also install pigz for multi CPU support which can speed up your backups:

yum --enablerepo=epel install pigz

smeserver Panel

There is no panel for manage this contrib, you have to play with db configuration command but normally the options by default could be sufficient.

How to launch the backup

You can launch manually the database backup by a command line with automysqlbackup in a root terminal.

automysqlbackup

otherwise every night, a cron job start à 4h00 AM to save your databases.

DB command option

If you want to see the db configuration of automysqlbackup.

config show automysqlbackup

Time

You can adjust the time when start the cronJob

• Each 30 Minutes

 config setprop automysqlbackup Hour '*' Minute '*/30'
 signal-event automysqlbackup-update

• Each Hour

 config setprop automysqlbackup Hour '*/1' Minute 1
 signal-event automysqlbackup-update

• At 3 Hour Am

 config setprop automysqlbackup Hour 3 Minute 1
 signal-event automysqlbackup-update

Backup directory

It is the folder where you save you database backup (default is /root/backup/db). This is the architecture of your backup folder.

	Note:
	keep in mind that the /root folder is saved with the e-smith-backup of your server-manager

#ls /root/backup/db/
daily  fullschema  latest  monthly  status  tmp  weekly

If you want to save in another place, you have to do the command below.

config setprop automysqlbackup Backupdir /path/to/other/folder

you have to create manually your new backup directory

mkdir -p /path/to/other/folder

Backup a local directory

the possibility is given to you to save a local directory by automysqlbackup. I suppose that you can not use it for large folder but for a web site with its database it could be useful. not activated by default

config setprop automysqlbackup Backup_local_files /path/to/folder

Mysql53, Mysql55, Mysql57, MariaDB

With SCL on SME you may be running other database versions.

You must make sure you have a backup user for the newer databases

Creating backup user for default mysql53 database
done
*** If you add mysql55/mysql57 you must add a backup user ***
You can use the password from config show automysqlbackup
e.g.: 
mysql55 -e " GRANT EVENT,SELECT,LOCK TABLES ON *.* TO backupuser@'localhost' " 
mysql55 -u root -e "SET PASSWORD FOR backupuser@localhost = PASSWORD( ' -from config show automysqlbackup DbPassword- ' ) " 

We can now choose other databases to backup:

mysql53, mysql55, mysql57, mariadb

You can enable or disable as follows:

config setprop mysql55 enabled
signal-event automysqlbackup-update

Encryption

If you wish to encrypt your backups using openssl (no is default)

config setprop automysqlbackup Encrypt yes

you need to set a password (default is 01234567899876543210)

config setprop automysqlbackup Dbencrypt_password your-password

	Note:
	This option may be useful when you want to save your databases outside of your server by sending them by mails. keep in mind to change the default password

Decryption

To decrypt run :

openssl enc -aes-256-cbc -d -in encrypted_file_name(ex: *.enc.gz) -out outputfilename.gz -pass pass:your-password

example :

openssl enc -aes-256-cbc -d -in daily_horde_2013-04-26_01h41m_Friday.sql.gz.enc -out daily_horde_2013-04-26_01h41m_Friday.sql.gz \
-pass pass:01234567899876543210

Mailcontent

you can choose your type of mail send to the admin (log by default)

config setprop automysqlbackup Mailcontent option

option :

• log : send only log file (default)
• files : send log file and sql files as attachments
• stdout : will simply output the log to the screen if run manually.
• quiet : Only send logs if an error occurs to the MAILADDR.

	Tip:
	Use the "files" option with the Mailcontent db to save your mysql databases in a mailbox outside of your server, moreover they are saved too in a local folder of your server (by default/root/backup/db)

Mailto

you can choose the mail account where you sent your mails (default is the mailbox admin of your server).

config setprop automysqlbackup Mailto foo@foo.com

Sizemail

you can determine the size of mails sent (default is 8000 KB).

config setprop automysqlbackup Sizemail 8000

	Note:
	keep in mind that a lot of smtp server reject mail bigger than 10 000 KB or 10MB

Manual Settings

There are many options you can modify in automysqlbackup, so for a personal need you can adjust by hand the files below. make a copy before.

cp /etc/automysqlbackup/myserver.conf /etc/automysqlbackup/myserver.conf-old
nano /etc/automysqlbackup/myserver.conf

RESTORING

restoring a .sql file

In a root terminal

cd /root/backup/db/ 

and choose your backup

gunzip file-name.sql.gz

Next you will need to use the mysql client to restore the DB from the sql file.

mysql database < /path/file.sql

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

If you want to play with another user or a remote mysql server you can use this command line

mysql --user=username --pass=password --host=dbserver database < /path/file.sql

restoring databases sent by mail attachment

The attachments have been split into multiple files, use this command line to combine them :

cat mail_attachment_2011-08-13_13h15m_* > mail_attachment_2011-08-13_13h15m.tar.bz2

and do this to extract the content

bunzip2 <mail_attachment_2011-08-13_13h15m.tar.bz2 | pax -rv

Known Issues

Skip mysql.event

• Warning: Skipping the data of table mysql.event. Specify the --events option explicitly. SOLVED in bugzilla:8146

See http://www.linuxbrigade.com/warning-skipping-data-table-mysql-event/#more-135 See this discussion http://bugs.mysql.com/bug.php?id=68376

Empty backupdir key

• Don't leave this key blank or you may get errors:

config show automysql Backupdir 

The system will try and default to /root/backup/db but you may get issues if it is empty

See bugs bugzilla:10655 and bugzilla:10654

Backup databases

• Some solutions :

if we want to backup databases

mysqldump -uroot --events mysql > /tmp/mysql.sql

or if we don't want to backup them

mysqldump -uroot --events --ignore-table=mysql.event mysql > /tmp/mysql.sql
