Monitoring MySQL backups is a vital part of any reliable backup solution. By monitoring the most common disaster recovery metrics, the Recovery Time Objective and the Recovery Point Objective, you can find out if a backup job was successful and produced a usable backup copy. The TwinDB Backup Tool along with Datadog allows monitoring both […]

If you ever tried to backup MySQL 5.7 with Percona Xtrabackup that comes in percona-xtrabackup package most likely you got error message like this: [crayon-5ba957f33e1f1811481611/] This happens because percona-xtrabackup actually installs version 2.3 that doesn’t support MySQL 5.7.

Percona Live is a Christmas in MySQL world. It’s time when all friends and family gather over a glass of beer. Everyone is talking about achievements of the last year and make New Year resolutions for a next one.

There will be two talks from TwinDB this year. One is about data recovery and one – about backups.

The data recovery talk is a kind of traditional talk. I will briefly cover InnoDB files format so you know where to look for data. I will show how to recover data from two most popular accidents: InnoDB tablespace corruption and DROP TABLE or DROP DATABASE. Data recovery is impossible without table structure recovery. I will show how to get the structure from an .frm file or from InnoDB dictionary (think of DROP TABLE when the .frm file is gone). We made a drastic improvement in user …

A week or two ago one of my former colleagues (at Percona) Jevin Real gave a talk titled Evolving Backups Strategy, Deploying pyxbackup at Percona Live 2015 in Amsterdam. I think Jervin raised some very good points about where MySQL backup solutions in general fall short. There are definitely a lot of tools and scripts out there that claim to do MySQL backups correctly, but don’t actually do it correctly. What I am more interested though is in measuring TwinDB against the points that Jervin highlighted to see if TwinDB falls short too.

Dependencies

We distribute TwinDB agent as a package that can be installed using the standard OS package management system. For example, using YUM on CentOS, RHEL and Amazon Linux, or using APT …
