Enterprise Systems Backup and Recovery If you 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.

Over at Daring Fireball, there’s a link at the moment to Wil Shipley’s article on implementing heuristics within various applications he works on (Mac OS X), particularly focusing in this article on the human factors of heuristics.
As a programmer and an author, I find the article interesting, because the lessons don’t just apply to the [...]
I had an odd question recently from a customer – they wanted to know whether NetWorker could tell them what inode a file had when it was backed up. Thankfully, having previous experience with NetWorker and AdvFS, I knew that NetWorker did keep track of inode details during the backup.
The way to find this out [...]
I was rather pleased this morning to have a friendly FedEx courier drop off Mac OS X 10.6 – Snow Leopard.
Of course, my first thought was “will this work with NetWorker?”
I’m pleased to report – yes, yes it does. All of the following worked for me using NetWorker 7.5.1:
Recoveries from prior to the upgrade
Backups following [...]
It’s a common misconception that, well, backup sucks. This for the most part seems to come from one of three sources: misunderstandings, issues, or vendors trying to sell you some New and Shiny Thing.
Invariably when someone tells me that backup sucks, it isn’t backup that sucks, it’s the design, implementation or processes at their site [...]
In the first article on the subject, What is a zero error policy?, I established the three rules that need to be followed to achieve a zero error policy, viz:
All errors shall be known.
All errors shall be resolved.
No error shall be allowed to continue to occur indefinitely.
As a result of various questions and discussions I’ve [...]
I routinely check (via the handy WordPress dashboard) what searches lead people to my blog. Often it’s for content that already exists on my site, but it also routinely helps me think of new topics to cover. (Occasionally it also provides some wry humour – for instance, someone a few weeks ago searched for “after [...]
It’s easy to get confused on ‘supported’. That is, when EMC (or any other vendor) publishes a guide on say, what operating systems are supported, many will ask whether that means if some operating system X that does not appear in the list will work.
The terms ‘work’ and ‘supported’ are not synonymous, and should not [...]
Referenced from undrln, there’s an article over at Business Week about some of the more innovative techniques being used in data visualisation. Data visualisation to me represents a fantastic merger between raw IT data mining and art/creativity. It’s about coming up with techniques that convey large amounts of information in a glance. As may be [...]
Or, I can’t see the emperor’s new clothes…
More than a decade ago, Sun bet its future on The Network Computer. We were supposed to see a fundamental shift in computing away from powerful local desktops to powerful centralised servers, with desktops being little more than multimedia capable terminals. The obvious advantage to this was that [...]
Last night I was lucky enough to see District 9. As a big Science Fiction fan, I enjoy scifi that doesn’t tread the same old ground, and District 9 certainly lived up to that.
At times it’s gory, that’s for sure, but at no point does it try to be a thriller or horror. This is [...]
