Selective Restore of InnoDB Tables with MySQL Enterprise Backup 3.11
Employee +1 Vote Up -0Vote Down

Introduction

Sometimes the best way to repair data issues and problems within a MySQL database is to restore only some of the tables from a backup. For example, suppose that some data was accidentally deleted from one table due to a software error, then the easiest way to recover the lost data might be to restore only one table from a backup. Previously this kind of partial restore was not supported by MySQL Enterprise Backup (MEB). However, MEB 3.11 introduces support for selective restore from backups created with the …

Data Encryption with MySQL Enterprise Backup 3.10
Employee +0 Vote Up -0Vote Down

Introduction

MySQL Enterprise Backup (MEB) 3.10 introduces support for encrypted backups by allowing backup images, or single-file backups, to be encrypted. However, backups stored in multiple files in a backup directory can not be encrypted.

Any MEB command that produces a backup image can be optionally requested to encrypt it. The encrypted backup image can be stored in a file or tape in the same way as an unencrypted backup image. Similarly, any MEB command that reads data from a backup image accepts also an encrypted backup image. This means that encrypted backups can be used in all the same situations as unencrypted …

–use-tts backup & restore
Employee +0 Vote Up -0Vote Down

In addition to my recent post, I just had to go into using the –use-tts for specific tables and selective backup sets.

As all my schemas were employeesn, I thought it would be a good idea to run:

mysqlbackup -uroot --socket=/tmp/mysql.sock --backup-dir=/home/mysql/MEB/restore \
--with-timestamp --use-tts --include=employees* backup

as I want all the tables. If I only wanted a specific table, say ‘salaries’ I could have done:

mysqlbackup -uroot --socket=/tmp/mysql.sock --backup-dir=/home/mysql/MEB/restore \
--with-timestamp --use-tts --include=employees*\.*salaries backup

Automating Backups
Employee +0 Vote Up -0Vote Down

If you need to automate backups, you might wonder about the different techniques available to you.

With regards to scheduling backups using built-in features of MySQL, you have two main options:

  • Either run mysqldump (or mysqlbackup if you have an Enterprise licence) from an operating system scheduler, for example in Linux using "cron" or in Windows using the "Task Scheduler". This is the most commonly used option.
  • Alternatively, use the Event Scheduler to perform a series of  SELECT ... INTO OUTFILE ... commands, one for each table you need to back up. This is a less commonly used option, but …
