MySQL Backup Service from Percona

The Percona Backup Service managed service launched today. It ensures properly configured backups run successfully as scheduled on customer provided backup storage – whether on premise, in the cloud, or a hybrid. Backup issues or production data recovery are efficiently handled by Percona Managed Services technicians with deep knowledge of MySQL.

As we state in our white papers, “MySQL backup and recovery are a foundational piece of any infrastructure. A well-tested backup and recovery system can be the difference between a

Why did we develop percona-agent in Go?
+0 Vote Up -0Vote Down

We recently open-sourced our percona-agent and if you check out the source code, you’ll find that it is written in the Go programming language (aka Golang). For those not up to speed, the percona-agent is a real-time client-side agent for Percona Cloud Tools.

Our requirements are quite demanding for our agents. This one is software that works on a real production server, so it must be fast, reliable, lightweight and easy to distribute. Surprisingly enough, binaries compiled by Go fit these characteristics.

There are of course alternatives that we considered. On the scripting side: Perl, Python, PHP, Ruby et al. These are not necessarily fast, and the distribution is also interesting.

Encrypted and incremental MySQL backups with Percona XtraBackup
+0 Vote Up -0Vote Down

We’ve recently received a number of questions on how to implement incremental MySQL backups alongside encryption with Percona XtraBackup. Some users thought it was not initially possible because with the default

--encrypt
options with XtraBackup, all files will be encrypted, but alas, that is not the case. This is where the option
--extra-lsn-dir
becomes useful, because it allows you to save LSN (Log Sequence Number) information to another directory and exclude it from encryption, allowing you to use the same information needed by incremental backups. Enough talk, let me show you.

Because you would want to usually script your backup and restore procedure, I’d use variables here as well to make you more familiar. First,

Innodb redo log archiving
+1 Vote Up -0Vote Down

Percona Server 5.6.11-60.3 introduces a new “log archiving” feature. Percona XtraBackup 2.1.5 supports “apply archived logs.” What does it mean and how it can be used?

Percona products propose three kinds of incremental backups. The first is full scan of data files and comparison the data with backup data to find some delta. This approach provides a history of changes and saves disk space by storing only data deltas. But the disadvantage is a full-data file scan that adds load to the disk subsystem. The second kind of incremental

Introducing backup locks in Percona Server
+1 Vote Up -0Vote Down

TL;DR version: The backup locks feature introduced in Percona Server 5.6.16-64.0 is a lightweight alternative to FLUSH TABLES WITH READ LOCK and can be used to take both physical and logical backups with less downtime on busy servers. To employ the feature with mysqldump, use mysqldump --lock-for-backup --single-transaction. The next release of Percona XtraBackup will also be using backup locks automatically if the target server supports the feature.

Now on to the gory details, but let’s start with some history.

In the beginning…

In the beginning there was FLUSH TABLES, and users messed with their MyISAM tables under a live server and were not ashamed. Users could do nice things like:

mysql> FLUSH TABLES;
# execute myisamchk, myisampack, backup / restore some

Changing an async slave of a PXC cluster to a new Master using 5.6 and GTID
+1 Vote Up -0Vote Down

Before Percona XtraBackup 2.1.7 and Percona XtraDB Cluster 5.6.15-25.3, rsync was the only SST method supporting GTID in the way that it was possible to move an asynchronous slave from one Galera node to another one (related bug).

Indeed, previous versions of Percona XtraBackup didn’t copy any binary log and due to that, moving the async slave to another master, just broke replication (when writes still happened).

Now with the latest version of Percona XtraBackup and Percona XtraDB Cluster, wsrep_sst_xtrabackup-v2 handles the last binlog

Percona XtraBackup – A workaround to the failed assertion bug
+1 Vote Up -0Vote Down

I recently conducted a test backup of my “master-slave” setup in my VirtualBox as I was migrating from Percona Server 5.6.12 to version 5.6.13-rel61.0 with Percona XtraBackup v2.2.0 rev. 4885. However, doing the backup on my slave, I encountered this problem:

[04] Compressing and streaming ./test/checksum.ibd
[01] Compressing and streaming ./mysql/slave_master_info.ibd
Assertion "to_read % cursor->page_size == 0" failed at fil_cur.cc:293

Handling long-running queries in MySQL with Percona XtraBackup
+0 Vote Up -0Vote Down

I recently had a case where replication lag on a slave was caused by a backup script. First reaction was to incriminate the additional pressure on the disks, but it turned out to be more subtle: Percona XtraBackup was not able to execute FLUSH TABLES WITH READ LOCK due to a long-running query, and the server ended up being read-only. Let’s see how we can deal with that kind of situation.

In short

Starting with Percona XtraBackup 2.1.4, you can:

  • Configure a timeout after which the backup will be aborted (and the global lock released) with the lock-wait-threshold, lock-wait-query-type and lock-wait-timeout options
  • Or automatically kill all queries that prevent the lock to be granted with the kill-long-queries-timeout and

Experimental GIT Mirrors of Percona XtraBackup, Percona Server plus Oracle MySQL trees

I recently blogged on setting up Experimental Git mirror of Oracle MySQL trees up on GitHub. I’m now happy to announce that there are also mirrors for:

I’ve also updated the Oracle MySQL GIT mirror to include MySQL 5.7 and the (now abandoned) MySQL 6.0. I include the abandoned 6.0 tree as it can provide useful archaeology as to where some code came from.

Growth of Percona software releases
+1 Vote Up -0Vote Down

It was once said that “real artists ship.” In looking over the history of Percona software releases, we are currently shipping more software than ever before.

First, let’s look at Percona Server. Let’s look at all major versions: 5.1, 5.5 and 5.6 as well as the total for each year. The estimate for 2013 comes from assuming the second half of 2013 is similar to the first half.

Percona Server releases per year

In 2011, when Percona Server 5.5 came along, we see a sharp reduction in Percona Server 5.1 releases (remember that there’s at least one Percona Server 5.1 release for each Oracle MySQL 5.1 release, and this reduction is likely a reflection of the reduction of

Limited disk space? Compact backups with Percona Xtrabackup 2.1
+1 Vote Up -0Vote Down

One very interesting feature, “Compact Backup,” is introduced in Percona XtraBackup 2.1. You can run “compact backups” with the  –compact option, which is very useful for those who have limited disk space to keep the database backup. Now let’s first understand how it works. When we are using –compact option with Innobackupex, it will omit the secondary index pages. This will make the backups more compact and this way they will take less space on disk but the

Migrating between MySQL schemas with Percona Xtrabackup
+0 Vote Up -0Vote Down

Recently, I was working with a client that asked about using Percona Xtrabackup to take a snapshot of a particular MySQL schema and then reload it with a different schema name on the same server.  It caught me off guard because I’d never really thought about it – typically, I’ve used Xtrabackup simply to clone a server (for replication or migration) or migrate an existing schema to a new server.  However, given the import/export functionality of Xtrabackup combined with Percona

Percona Live MySQL Conference and Expo 2013: It feels like 2007 again
+3 Vote Up -1Vote Down

I actually don’t remember exactly whether it was in 2006, 2007 or 2008 — but around that time the MySQL community had one of the greatest MySQL conferences put on by O’Reilly and MySQL. It was a good, stable, predictable time.

Shortly thereafter, the MySQL world saw acquisitions, forks, times of uncertainly, more acquisitions, more forks, rumors (“Oracle is going to kill MySQL and the whole Internet”) and just a lot of drama and politics.

And now, after all this time some 6 or 7 years later, it feels like a MySQL Renaissance. All of the major MySQL players are coming to the
