Backup Software and The Long Tail of Open Source
+0 Vote Up -0Vote Down

An addition to The Long Tail of “The Long Tail” related blogs

The Long Tail effect of open source has been discussed in several contexts. Some of the interpretations are likely very different from what Chris Anderson intended, but more and more niche needs of a relatively small set of people (which don’t have economies to justify product development by proprietary software companies) are being met by open source software. Witness more than 140,000 projects registered on SourceForge.

Whenever I install Red Hat Linux I am amused by some of the choices available for the language of the operating system - what is different when running a Red Hat box with English(Singapore) vs. English(India)!? It is also heartening to see support for regional languages making computers accessible to

Personal comments about recently published results of Amanda usage survey
+0 Vote Up -0Vote Down

We just published the results of Amanda usage survey and I want to share my personal observations.One of the most inspiring findings is that 95% of respondents would recommend Amanda to a friend. The Loyalty expert Fred Reichheld would be very impressed with such a result. The overall satisfaction with Amanda is also highlighted by the fact that 70% of respondents have been using Amanda for more than 2 years. People use software for such a long time only if it does the job well. Many users reported that Amanda was up to the task recovering files in most critical situations.

I think it is just great that more than 60% of users provided suggestions for new functionality.

Here are the

Backup and recovery of the remote MySQL server with ZRM
+0 Vote Up -0Vote Down

We just published a technical document about what to consider for backup and recovery of the remote MySQL server, for example, when your online forums and wiki are located at managed hosting service provider.

For any database backup the primary considerations are the consistency of the backup and impact on users and applications. A backup of the remote MySQL, however, has extra challenges related to:

  • network usage
  • security, and
  • flexibility of recoverability of MySQL data to a different host.

We discuss the trade-offs to consider, and describe how to use Zmanda Recovery Manager (ZRM) for several common scenarios. For example, we provide HOWTO for a use case when you want to ensure security of backup data on the wire and at rest.

Detecting malicious database activity
+0 Vote Up -0Vote Down

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
