    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.

This holiday season, give your inner geek a gift

Posted by Preston on 2009-12-11

As it approaches that time for giving, it’s worth pointing out that with just a simple purchase, you can simultaneously give yourself and me a present. I’m assuming regular readers of the blog would like to thank me, and the best thanks I could get this year would be to get a nice spike in sales in my book before the end of the year.

Enterprise Systems Backup and Recovery: A corporate insurance policy” is a book aimed not just at companies only now starting to look at implementing a comprehensive backup system. It’s equally aimed at companies who are already doing enterprise backup and need that extra direction to move from a collection of backup products to an actual backup system.

What’s a backup system? At the most simple, it’s an environment that is geared towards recovery. However, it’s not just having the right software and the right hardware – it’s also about having:

  • The right policies
  • The right procedures
  • The right people
  • The right attitude

Most organisations actually do pretty well in relation to getting the right software and the right hardware. However, that’s only about 40% of achieving a backup system. It’s the human components – that last remaining 60% that’s far more challenging and important to get right. For instance, at your company:

  • Are backups seen as an “IT” function?
  • Are backups assigned to junior staff?
  • Are results not checked until there’s a recovery required?
  • Are backups only tested in an adhoc manner?
  • Are recurring errors that aren’t really errors tolerated?
  • Are procedures for requesting recoveries adhoc?
  • Are backups thought of after systems are added or expanded?
  • Are backups highly limited to “save space”?
  • Is the backup server seen as a “non-production” server?

If the answer to even a single one of those questions is yes, then your company doesn’t have a backup system, and your ability to guarantee recoverability is considerably diminished.

Backup systems, by integrating the technical and the human aspect of a company, provide a much better guarantee of recoverability than a collection of untested random copies that have no formal procedures for their creation and use.

And if the answer to even a single one of those questions is yes, you’ll get something useful and important out of my book.

So, if you’re interested in buying the book, you can grab it from Amazon using this link, or from the publisher, CRC press, using this link.

October Hits

(We interrupt this regularly scheduled blog article with a reminder that Enterprise Systems Backup and Recovery: A Corporate Insurance Policy is currently on-sale with the publisher, CRC Press, as well as continuing to be available from such other fine online retailers as Amazon and others. Don’t forget – having enterprise class backup and recovery software is only just part of the equation in ensuring that you have a well running and reliable backup and recovery system. For comprehensive details about building that complete and reliable system, the book is an indispensable resource.)

So with October over, we’ve got some clear winners in the blog-article popularity stakes. Driven by search engine referrals we have a return to the top of the “Basics – Fixing NSR Peer information errors“. This is something that a constant turnover of visitors to the blog.

Here’s a thought: it’s time this should be addressed in the NetWorker Management Console. That’s right, instead of having NetWorker just log these warnings/errors, it would be handy if instead there was a section of NMC devoted to “intervention required” events … let’s see, that would probably fit most in the monitoring panel, and could even be reported under logging, with a double-click on the event to lead into a dialog box/session offering to delete the offending peer information if and only if the NetWorker administrator were certain that the host wasn’t being spoofed.

If you’re wondering why you need to fix these errors, it’s simple: they cause all sorts of issues when it comes time to recovery – either directly when trying to recover data for that client back onto that client, or as part of a directed recovery.

I thought I’d just interrupt the regular flow of NetWorker commentary to recommend that you check out my book, Enterprise Systems Backup and Recovery: A Corporate Insurance Policy. (If you follow that link across to Amazon, you’ll be able to peruse some of the content of the book through Amazon’s nifty preview feature.)

The book distills much of my experiences with enterprise data protection and is focused on helping companies better understand the placement of backup within their environment, as well as getting an idea of procedures and policies that need to be in place to turn a backup solution into a backup system. This covers off a breadth of topics including, but not limited to:

  • Enterprise backup concepts overview
  • Roles of staff within the backup environment – not just IT staff!
  • Where backup fits within an environment
  • Total backup solutions – determining what should be backed up, and how
  • Recovery and disaster recovery guidelines and preparedness
  • How to test
  • Performance tuning guidelines and recommendations

If you’re after a bit more information on the book, you can also check out the accompanying site, Enterprise Systems Backup.

Regardless of which backup solution you use, you’ll find valuable information in the book.
