Survey Image

It seems like only a few weeks ago, 2017 was starting. But here we are again, and it’s time for another NetWorker usage survey. If you’re a recent blog subscriber, you may not have seen previous surveys, so here’s how it works:

Every year a survey is run on the NetWorker blog to capture data on how businesses are using NetWorker within their environment. As per previous years, the survey runs from December 1 to January 31. At the end of survey, I analyse the data, crunch the numbers, sacrifice a tape to the data protection deities and generate a report about how NetWorker is being used in the community.

My goal isn’t just for the report to be a simple regurgitation of the data input by respondents. It’s good to understand the patterns that emerge, too. Is deduplication more heavily used in the Americas, or APJ? Who keeps data for the longest? Is there any correlation between the longevity of NetWorker use and the number of systems being protected? You can see last year’s survey results here.

To that end, it’s time to run the 2017 NetWorker survey. Once again, I’m also going to give away a copy of my latest book, Data Protection: Ensuring Data Availability. All you have to do in order to be in the running is to be sure to include your email address in the survey. Your email address will only be used to contact you if you win.

The survey should hopefully only take you 5-10 minutes.

Dec 012015

It’s that time of the year again where I ask my readers and the NetWorker Community to spend a few minutes of their time answering some questions on how NetWorker is used within their environment. So your forbearance is greatly appreciated.

Each year I pose this survey and run it through from 1 December through to 31 January the following year – a straight 2 months. This year there’s 23 questions – a slight expansion on previous years, but I want to try to start gathering a bit of data on a couple of other topics, but I still believe this is something that will take no more than 5-10 minutes of your time. In return, you get to contribute to the NetWorker Usage Report that I generate in February each year. And trust me, now that I work in EMC, I’m well aware of how useful product managers find these reports, so this is well and truly your opportunity to provide real feedback as to how you use the product.

Edit, December 2: Product management reached out to me and ask if I could ask about CloudBoost, so I’ve added a 24th question to the survey.

While the survey is anonymous, it does offer a prompt for your to provide your email address, and for this survey there’ll be a prize: a signed copy of my upcoming book on Data Protection. This is a much broader tome of work than my previous book, Enterprise Systems Backup and Recovery, a Corporate Insurance Policy. At the moment the book is still under development, but it will be published next year, and if you want to be in the running for the book, please add your email address to the survey results. Your email address will be kept confidential. (I’ll notify the winner individually and then once the book is published, contact the winner for shipping details.)

Edit: The survey is now closed. Thanks for participating! Results coming in February 2016.

Nov 162015

Regular visitors will have noticed that has been down quite a lot over the last week.

I’m pleased to say it wasn’t a data loss situation, but it was one of those pointed reminders that just because something is in “the cloud” doesn’t mean it’s continuously available.

Computer crashed

In the interests of transparency, here’s what happened:

  • The domain, it turned out, was due for renewal December 2014.
  • I didn’t get the renewal notification. Ordinarily you’d blame the registrar for that, but I’m inclined to believe the issue sits with Apple Mail. (More of that anon.)
  • My registrar did a complimentary one year renewal for me even without charging me, so got extended until December 2015.
  • did get a renewal notification this year and I’d even scheduled payment, but in the meantime because it was approaching 12 months out of renewal, whois queries started showing it as having a pendingDelete status.
  • My hosting service monitors whois and once the pendingDelete status was flagged stopped hosting the site. Nothing was deleted, just nothing was served.
  • I went through the process of redeeming the domain on 10 November, but it’s taken this long to get processing done and everything back online.

So here’s what this reinforced for me:

  1. It’s a valuable reminder of uptime vs availability, something I’ve always preached: It’s easy in IT to get obsessed about uptime, but the real challenge is achieving availability. The website being hosted was still up the entire time if I went to the private URL for it, but that didn’t mean anything when it came to availability.
  2. You might be able to put your services in public-cloud like scenarios, but if you can’t point your consumers to our service, you don’t have a service.
  3. In an age where we all demand cloud-like agility, if it’s something out of the ordinary domain registrars seemingly move like they’re wading through treacle and communicating via morse code. (It took almost 4 business days, three phone calls and numerous emails to effectively process one domain redemption.)
  4. Don’t rely on Apple’s iCloud/MobileMe/.Mac mail for anything that you need to receive.

I want to dwell on the final point for a bit longer: I use Apple products quite a bit because they suit my work-flows. I’m not into (to use the Australian vernacular), pissing competitions about Apple vs Microsoft or Apple vs Android, or anything vs Apple. I use the products and the tools that work best for my work-flow, and that usually ends up to be Apple products. I have an iPad (Pro, now), an Apple Watch, an iMac, a MacBook Pro and even my work laptop is (for the moment) a MacBook Air.

But I’m done – I’m really done with Apple Mail. I’ve used it for years and I’ve noticed odd scenarios over the years where email I’ve been waiting for hasn’t arrived. You see, Apple do public spam filtering (that’s where you see email hitting your Junk folder), and they do silent spam filtering.  That’s where (for whatever reason), some Apple filter will decide that the email you’ve been sent is very likely to be spam and it gets deleted. It doesn’t get thrown into your Junk folder for you to notice later, it gets erased. Based on the fact I keep all of my auto-filed email for a decade and the fact I can’t find my renewal notification last year, that leaves me pointing the finger for the start of this mess at Apple. Especially when, while trying to sort it out, I had half a dozen emails sent from my registrar’s console to my account only to have them never arrive. It appears Apple thinks my registrar is (mostly) spam.

My registrar may be slow to process domain redemptions, but they’re not (mostly) spam.

A year or so ago I started the process of migrating my email to my own controlled domain. I didn’t want to rely on Google because their notion of privacy and my notion of privacy are radically different, and I was trying to reduce my reliance on Apple because of their silent erasure habit, but the events of the last week have certainly guaranteed I’ll be completing that process.

And, since ultimately it’s still my fault for having not noticed the issue in the first place (regardless of what notifications I got), I’ve got a dozen or more calendar reminders in place before the next time needs to be renewed.

Aug 262012

It’s been a while since I’ve posted anything, and that’s not really what I intended. I had hoped to do a rolling series of articles about NetWorker 8, but somewhere along the line my workload took a huge spike, and my personal life got busier, too.

So those articles I intended to pen weeks ago? Well, weeks have gone by and I’ve barely managed to put together a paragraph on either synthetic fulls or multi-tenancy in NetWorker 8.

I can’t promise those articles are going to appear this week – in fact, I can practically guarantee it. In fact, I may actually do one or two other articles first in the coming 2 weeks, including a very brief survey I’d like to run, before I get back to dissecting NetWorker 8.

Again, apologies – hopefully I’ll get back to my regularly scheduled programming soon.

Mar 152012

I’ve been pretty quiet of late on the site, and it’s not through a lack of interest. Unfortunately there’s several major challenges that I’m currently dealing with that are diverting most of my attention from all kinds of writing – not just this blog, but also my personal blog too.

Most of the articles I’m thinking of for the blog at the moment require more extensive testing and research – or are multi-part ones that require a lot more spare time to be allocated to them. However, I’m not getting a lot of that spare time at the moment – the place we’re renting is up for sale and as a result of that it seems every second day I’m dealing with another open-for-inspection, etc. It’s also fairly draining, so between that and work projects, I’m just not getting a lot of energy to devote to the site.

Things should start to ease in a couple of weeks; we should know by that stage whether an investor or an occupier has bought the property, and even if that means a move, it’ll at least be a period of action rather than a draining holding pattern.

So, bear with me: there is new content being worked on, it’s just my window of opportunity to work on it is a little small at the moment.


Dec 212011

It’s that time of the year where I sit back for a moment and look at what articles have attracted the most readers over the year, and it’s a fairly eclectic bunch. Interestingly, for the first time since forever, the article about fixing NSR Peer Information issues didn’t come first – we have some new winners.

10 – New Micromanual – LinuxVTL and NetWorker

The second micromanual was a step-by-step guide for configuring the open source LinuxVTL system with NetWorker. I had hoped when I started writing micromanuals that I’d get them more frequently delivered, but various factors get in the way of this. Maybe in 2012 I’ll be able to get a couple more out and available.

9 – Killing scheduled cloning operations

When NetWorker’s scheduled clone option was introduced, there were a few bugs relating to stopping a scheduled clone operation from the GUI. Sometimes you could, and sometimes you couldn’t. However, you could always kill a scheduled clone job from the command line, which is what this post explained.

8 – NetWorker Firewall Configuration on Windows

Very early in the year I was doing a lot of work with NetWorker on Windows 2008 R2, and I was noticing a few gaps in the installation process when it came to the process of automated configuration of the Windows Firewall to work with NetWorker daemons. This post explained the lessons I learnt.

7 – Carry a jukebox with you (if you’re using Linux)

This article was my first post about configuring the open source LinuxVTL system with NetWorker. Since then LinuxVTL has evolved quite a lot, and I’ll likely even need to update that micromanual early in the new year as a consequence.

6 – Why I’d choose NetWorker over NetBackup Every Time

Despite the fact that the article was titled “Why I’d choose…”, I had a rather indignant response to this post insisting I was being a jerk by writing it. I stand by every word in that post. I would not, personally, elect to choose NetBackup over NetWorker on the basis that NetBackup only has true image recovery as an option, and that NetBackup doesn’t support dependency chains for backup images. I see both of these factors as critical to a true enterprise backup product, and NetBackup only half supports one of them. That doesn’t make me a jerk, it makes me someone who gives a damn about your data.

5 – Using NetWorker Client with Opensolaris

A guest article written by Ronny Egner, this post covered off getting the NetWorker client working with the OpenSolaris version of Solaris.

4 – Basics – Fixing “NSR peer information” errors

A persistent challenge in NetWorker is when the NSR peer information gets out of whack; usually this can happen when a significant change happens on a client, and the server must have this information reset. I’d still love to see this article become irrelevant by seeing an option appear in NMC to handle it, but until then, this will remain a fairly popular article.

3 – This is wrong

Earlier this year, an Australian hosting service lost thousands of hosted domains and websites due to a “hack attack”. Supposedly the clever hackers destroyed not only the production data, but also all the backups.

What really went wrong was that the company in question had designed a very poor and inadequate backup solution. Rumours were abounding at the time that backups were just simply replicated snapshots. Snapshots may be able to act as backups, but not indefinitely, and not if they’re the only thing configured. (Backups and snapshots are effectively ‘sister’ activities in ILP.)

2 – micromanual: NetWorker Power User Guide to nsradmin

The original micromanual – “NetWorker power user guide to nsradmin” was and remains extremely popular. There’s been thousands of downloads of it since its release, including quite a number from EMC themselves, so it’s clearly a handy resource. If you’ve not downloaded it yourself but you want to boost your NetWorker productivity, it’s a must read.

1 – NetWorker 7.6 SP1

When NetWorker 7.6 SP1 came out, it was a huge release. In my opinion, it should have been numbered NetWorker 7.7 at least; it wasn’t a minor set of changes or a round of bug fixes, it included significant functionality updates (including one of my favourites – support for Boost). As the number one read article of the year, it’s been a big resource for people looking at the functionality of newer releases of NetWorker.

And that, they say, is that

This year has personally been a huge year for me. My partner and I moved state/city in June, going from a regional area just outside of Sydney to the inner west of Melbourne. We also celebrated our 15th anniversary together, surrounded by many of our new friends (who are like family to us) and a few of our old friends. We were even invited to get on the radio to talk about that, not only from the longevity of the relationship and having run the anniversary party up against the monthly Melbourne Den night. (There’s a podcast coming…) It was also the year when I sorted a lot of stuff out, and to boil all this down: it was the year that I spent a lot of time focusing on my personal life and not so much on the blog.

There may still be one or two posts left for 2011, but I’m also starting to get my head around changes and new material for 2012, and I believe 2012 will be a big year for NetWorker users.

After an 8+ hour outage on my domain this week, with no explanation from my hosting provider, I’ve finally had enough!

So, over the coming weeks, as I get things setup in the background, there may be brief outages on this blog as I transfer across to a new, better and more stable hosting provider.

Apologies, in advance, for any disruption.



Nov 172010

In March this year, I ran a NetWorker Usage Survey to gauge the lay of the land in terms of how and on what NetWorker is deployed within the user community. As a result of that, hundreds of people downloaded the March 2010 NetWorker Usage Survey Report.

It’s time to revisit that survey; I’ve adjusted the questions a little based on some of the responses from the previous survey results, and I’m keen for as many answers as possible to make this a worthwhile report. (Don’t forget, the report will be free to download.)

I’ll be aiming to keep the survey running until the end of November, and publish the results early in December. So please, fill out the survey below and have your say!


The survey has now closed. The report will be posted soon.

Amazon are currently selling Enterprise Systems Backup and Recovery: A Corporate Insurance Policy at a reduced price.

If you’ve been wanting to buy it, but the price has previously put you off, this may be a good excuse to go back and revisit Amazon for it.

Remember if you do read it that reviews are always welcome!
