    If you find this blog interesting, and either have an interest in or work in data protection/backup and recovery environments, you should check out my book, Enterprise Systems Backup and Recovery: A Corporate Insurance Policy. Designed for system administrators and managers alike, it focuses on features, policies, procedures and the human element to ensuring that your company has a suitable and working backup system rather than just a bunch of copies made by unrelated software, hardware and processes.

Release notes are your friend

Posted by Preston on 2009-07-20

To me the most valuable documents produced by EMC in relation to NetWorker or the modules are the Release Notes. These accompany any cited version update and typically contain at least the following chunks of information:

  • New features to the product
  • Changes to existing behaviour
  • Fixed problems
  • Known issues and limitations

This information is gold. To anyone thinking of updating either a NetWorker server or a NetWorker module who isn’t planning on thoroughly reading the release notes first I say this: are you nuts?

I’m the first to admit that I don’t re-read the administration guides every time they are updated. There’s just too much content in them. Instead, I rely on the release notes to tell me what has been added, and if any of that is relevant to my needs, I go searching through the administration guides for said information. In fact, I consider the release notes important enough that they’re the only NetWorker documentation I ever print. Why do I print them? Because it means I can take them away from the computer and go sit down and read them carefully – very carefully.

The release notes don’t always contain all information about an update. They also may not fully elucidate on particular problems that have been fixed*.

To me the most important aspect to the release notes – the bit I check first, is the “Known problems and limitations”. Why? This is the bit that gives you the warnings of “things that don’t work”, or “things that you may have to pay more attention to than you would otherwise think to”. I.e., what is known to not work. One would ignore these in particular at ones own peril.

So, next time you’re thinking of updating any part of your NetWorker environment, please, make sure you download and read the release notes.


* I can attest to this when I review release notes and see LGTscABCDEF numbers that have been created in response to bug filings I’ve made … a 2-3 line entry can’t convey all the details of sometimes complex, sometimes esoteric escalations.
