Detecting malicious database activity

I was talking to a customer yesterday and the customer was surprised that database backups can be used to detect malicious database activity from legitimate users and hackers.

ZRM for MySQL stores MySQL binary logs as part of the database backups. The binary logs provide a good audit trail of all database activity. ZRM for MySQL binary log parsing capability, usually used for selective point in time recovery, can also be used to detect malicious database activity using SQL inspection.

ZRM for MySQL plugin interface allows DBAs to write log parser plugin scripts to track the database activity that they are interested in. For example: the following script can be used to detect deletion of data from the PRODUCTS table in the database. This script …

Retain your MySQL Binary Logs until needed - but no longer (using Zmanda Recovery Manager)

ZRM for MySQL requires binary logging to be enabled on the MySQL server to do incremental backups. Enabling binary logs has minimal impact on MySQL performance. But, in an active database, the binary logs can grow to hundreds of gigabytes or even terabytes.

ZRM of MySQL has multiple plugin interfaces to customize the backup and recovery process to user environment. One of the plugin interfaces is the post backup plugin. The binary logs are no longer required after a backup. The post backup plugin can purge the binary logs after the backup. This will allow the system administrators to balance between the need for …

What is the optimal backup method for MySQL databases?

Goal of a MySQL system administrator is to have regular, consistent backups of the
databases with minimal impact on the database application. The backup process should
also limit the use of CPU, memory, network resources so that application is not impacted.
Optimal backup method must be choosen to keep the backup window as small as possible.
The backup parameters depends on various factors - number and size of databases, number
of MySQL servers, MySQL configuration, data security.

ZRM for MySQL provides consolidated backup and recovery for MySQL databases. ZRM
for MySQL provides extensive list of options to tune the backup process for the user
environment. It also tracks lots of backup parameters that are available to the administrator
to tune the backup process.

ZRM for MySQL and MySQL Online Backup

I had organized a session at MySQL camp on Saturday on the above topic. I should say I was one of the guilty ones who had slides for the session in an “unconference“.

Brian Aker (of MySQL) graciously stepped in to answer some questions and provided reasons for some of the design decisions in MySQL OnlineBackup. Some of them are:

  • Envelope format for backup archive. This would allow backup as well as recovery to continue in case the storage engines failed to do backup or recovery respectively.
  • Block size and envelope format will help in handling tape errors.
  • Logical backup will be done in case storage engine does not have online backup API …
