Holland is an application which is used for MySQL Backups.

Below are some steps to Install and Configure Holland to backup multiple datasets.

Install

First off, download the key.

wget http://download.opensuse.org/repositories/home:/holland-backup/xUbuntu_14.04/Release.key -O - | sudo apt-key add -

Add Holland to the Repo lists..

echo 'deb http://download.opensuse.org/repositories/home:/holland-backup/xUbuntu_14.04/ ./' > /etc/apt/sources.list.d/holland.list

Make sure you change 14.04 to the version of Ubuntu you are using. for both steps above.

apt-get update && apt-get install holland-common holland-mysqldump

Configuration.

How to get Holland to backup datasets from different MySQL instances (db01 and db02).

cp /etc/holland/backupsets/default.conf /etc/holland/backupsets/db01.conf;cp /etc/holland/backupsets/db01.conf /etc/holland/backupsets/db02.conf

root@web01:~# ls -l /etc/holland/backupsets/db*

-rw-r--r-- 1 root root 1466 Nov 17 10:53 /etc/holland/backupsets/db01.conf
-rw-r--r-- 1 root root 1466 Nov 17 10:53 /etc/holland/backupsets/db02.conf

In each of these files you will need to perform the changes below:

backups-to-keep = 5
databases       = *
exclude-tables  = mysql.events
[mysql:client]
user = root
host = mydatabasehost.example.com OR 123.456.789.123
password = MySecurePa$$word

The configuration above will keep 5 sets of holland backups, backup all databases and tables EXCEPT `mysql`.`events`

The settings under the [mysql:client] block will need to be changed on both servers to give correct login details to the database host.

Now we have the datasets created we need to amend the /etc/holland/holland.conf to actually backup these datasets rather than the default. The backup_directory is where you would like the backups to be stored once then have been processed. The backupsets is which config files to read and perform backups on.

backup_directory = /var/backups/mysql
backupsets       = db01, db02

That’s it! Configuration complete! All thats left to do is run the backup!

holland bk

Here are some more useful holland commands.

   backup        (bk)   Run backups for active backupsets
   help          (h)    Show help for a command
   list-backups  (lb)   List available backups
   list-plugins  (lp)   List installed plugins
   mk-config     (mc)   Generate a config file for a backup plugin
   purge         (pg)   Purge the requested job runs

If you want to configure holland to backup daily, then you can create a cronjob to run at a specific time.

echo '00 02 * * * holland bk' > /etc/cron.d/holland

This will run holland at 2am daily.
