System Administrators Toolkit: Backing up key information

Keeping a copy of the vital information that makes up your Unix environment could mean the difference between working again after a failure in hours compared to days. In the latest of my System Administrators Toolkit guide, I examine how best to identify and then back up the files that make up your system - not the data, but the configuration files, drivers and other elements that make you system unique.

In the article, I cover:

  • How to identify the right files, and what to consider
  • Simple script using tar to back up the files you want
  • Script for deleting files by date or age
  • Using rsync for backups

Opening up comments (thanks Akismet)

For a long time I disabled comments on the site because I received a huge amount of comment spam. I’ve been running with Akismet now for months (and filtered over 11,000 items in the process), so I’m going to open up the site for comments.

You’re still going to need to register, but otherwise feel free to get involved!

Best intentions

I started out this blog (in fact, it’s one and only post) talking about how I was going to talk about what it was like to be a writer and the many things that you ultimately end up having to do and deal with as you cope with becoming and working as a writer.

It seems only appropriate that I should make my next post on the pitfalls that lead you to never following through on your original thoughts.

That first post was back in December 2005 - eight months   (more...)

Photo blogging with the K800i

As planned, I got a K800i earlier this week, and it’s taken me the best part of the week to try and sort out all of the different elements. I already did a quick post on Convergence in mobile phones with the SE K800i at ComputerWorld, but I thought it would be worth looking at some of the other elements.

With Mac OS X, it doesn’t take much work to get everything set up, but it has taken me a while to sort out and organize some of the more fun elements. Getting the phone syncing with my address book was achieved using the plugin available from feisar.com.

To populate the audio so that I can use it for what I used to employ the iPod shuffle for, I used iTunes to create 128Kbps AAC files; when you connect the camera through the supplied USB cable, the Memory Stick Micro card appears on the desktop just like a USB thumb drive - so you can copy the files (including the folders) over so you can play them. Playback through the headphones is great. Through the built-in speaker, it’s good enough to use in a small room for some ambient noise. My only problem now is remembering to pick up the headphones each time I leave.

I’ve also set up the email for the phone so that I can pick up emergency messages on the phone when away from the office. The phone has it’s own email address (technically it has two, my own and one provided by the mobile phone operator (O2)), and I’ve set up some rules within sieve to forward specific types of message to the phone.

As I hoped (and to be honest, expected) the quality of the camera is superb, and I love the way you can use this to blog directly just by pressing a button (you can see the results and quality at Martin MC Brown’s Mobile Blog. OK, so I might be late to the whole mobile blogging thing, but honestly, it works so great that my mother could be doing this.

The camera itself works just like a Sony camera - you get the same controls, zoom, built in flash, auto-focus and you can set a full range of options, like metering mode, white balance and selected special photo subjects with corresponding optimized settings. The results are obviously less expansive than those on my Sony P200, but definitely a good range given that we are talking about the camera built into a mobile phone.

Having said for years I was never going to get a mobile phone with a built in camera, I can now imagine a situation where the walks to the post office or those ever-so-rare cat shots suddenly become possible (nay, necessary) when I can publish them straight to the blog from the phone.

Expect more photos and experience notes as I get to use the camera more. Afterall, I’m still yet to actually make or receive a phone call!

Live Search Plugin

I’ve noticed that a larger number of people come to the site and start searching for a particular entry, so I’ve decided to add the excellent Wordpress Live Search Plugin to the site.

Now when you search, you’ll get a live list beneath the search panel of the matching posts, which you can click on to go straight to the post in question.

Installing the plugin itself is easy, download it, put it in your plug-in directory, and enable it. Providing you’ve used the standard search panel, the live component is enabled immediately.

The Live Search plugin has been enabled on the MCslp Coalface and Planet MCslp sites too.

T1000 in more detail

I've been testing a Sun T1000 now for about the last three months. This was after I said goodbye to my T2000, with much sadness, back in May.

At first glance, the T1000 and T2000 look like the same basic construction, but with the T1000 supporting fewer internal drives. That's not completely true - the T1000 is only 1U high and to keep with the necessary cooling and the reduced height, some of the internal elements have been trimmed too. The less complicated internals should in theory be a bonus, because with less complicated components, and fewer numbers of them, there should be fewer things to go wrong, which in turn should have a real impact on the MTBF (Mean Time Between Failures). It's difficult over three months to say that categorically, but the theory is sound.
