+0 Vote Up -1Vote Down

Overview

Cloud storage is becoming more and more popular for offsite storage and DR solutions for many businesses. This post will help with those people that want to perform this process for MySQL backups directly into Amazon S3 Storage. These steps can probably also be adapted for other processes that may not be MySQL oriented.

Steps

In order to perform this task we need to be able to stream the data, encrypt it, and then upload it to S3. There are a number of ways to do each step and I will try and dive into multiple examples so that way you can mix and match the solution to your desired results.  The AWS S3 CLI …

+0 Vote Up -0Vote Down

After upgrading Percona Server 5.6.28 (and "full stack" of Percona software) to 5.7.10-3 GA on CentOS 6 and building it from Git Source on Fedora Core 23 yesterday, I've decided to spend some time upgrading Percona Server on my netbook that plays a role of "home build/test/VMs server" and runs under Ubuntu 14.04:
openxs@ao756:~$ uname -a
Linux ao756 3.13.0-77-generic #121-Ubuntu SMP Wed Jan …

On Upgrades to Percona Server 5.7 GA: CentOS 6 Case
+1 Vote Up -0Vote Down

As you probably noted, Percona had finally released Percona Server 5.7 GA two days ago. I had not paid much attention to this branch during last month or so, but as it's GA now I decided to check what's there, how it works and install/upgrade different boxes and VMs to use it.

For testing purposes and for this series of blog posts I am going to build it from Git source (at least on Fedora Core 23), upgrade to it on 32-bit …

+0 Vote Up -0Vote Down

Not so long ago I had a customer who experienced data loss after MySQL restart. It was really puzzling. MySQL was up & running for many months, but after the customer restarted MySQL server all tables have gone. The tables were still visible in SHOW TABLES output, but they were not readable:

mysql> show tables like 'actor';
+--------------------------+
| Tables_in_sakila (actor) |
+--------------------------+
| actor                    |
+--------------------------+
1 row in set (0.00 sec)

mysql> select * from actor;
ERROR 1146 (42S02): Table 'sakila.actor' doesn't exist

Optimizing PXC Xtrabackup State Snapshot Transfer
+0 Vote Up -0Vote Down

State Snapshot Transfer (SST) at a glance

PXC uses a protocol called State Snapshot Transfer to provision a node joining an existing cluster with all the data it needs to synchronize.  This is analogous to cloning a slave in asynchronous replication:  you take a full backup of one node and copy it to the new one, while tracking the replication position of the backup.

PXC automates this process using scriptable SST methods.  The most common of these methods is the xtrabackup-v2 method which is the default in PXC 5.6.  Xtrabackup generally is more favored over other SST methods because it is …

+0 Vote Up -0Vote Down

December 8, 2014 By Severalnines

Percona XtraBackup is a great backup tool with lots of nice features to make online and consistent backups, although the variety of options can be a bit overwhelming. s9s_backup tries to make it simpler for users, it creates an easy to use interface for XtraBackup features such as full backups, incremental backups, streaming/non-streaming, and parallel compression.

Backups are organized into backup sets, consisting of a full backup and zero or more incremental backups. s9s_backup manages …
