Backup your sandbox with XtraBackup

. Minggu, 29 April 2012 .

Today I tried to make incremental backups of a MariaDB instance in a MySQL sandbox with Percona XtraBackup.
I used the recently released XtraBackup 2.0. And of course there is documentation about making incremental backups. 

MySQL sandbox makes it easy to run many different MySQL versions on one machine. It does this by changing the port number, data directory, UNIX socket location and a whole lot more.

So I first started with a full backup and after that I used that backup as a base for the incremental backups. To do that I had to specify the port number which is 5522 and the username and password for the msandbox account. As MySQL uses a UNIX socket instead of a TCP connection if the hostname is localhost I specified 127.0.0.1 as hostname to force a TCP connection. That worked!

Then I created the incremental backup by using the --incremental option and the --incremental-basedir option to specify the location of the full backup. That also worked!
