If you didn’t know, this has been a tumultuous week for clients of Westhost, my internet service provider. Their Primary data center is located in Utah and they share that space with a sister brand VPS.net. The datacenter is a Tier IV center managed by Consonus. Saturday afternoon there was a yearly fire equipment/alarm/suppression system test. The third party technician failed to follow procedures and one actuator remained on the output system for the gas that is designed to suppress fires in the building. When the system was re-armed there was a sudden release of the gaseous fire suppressant. At that same moment hundreds of hard drives died. Now, Inergen is what was used and the gases themselves shouldn’t be a problem. In this case, and judging from what I’ve read, the problem was with the sudden and intense change in air pressure caused by the release. That point is somewhat moot though, the end result is hundreds of dead and damaged hard drives.

The Risk of Cloud Computing, Trust
There’s a lot of buzz these days about “cloud computing”. You may be asking yourself just what IS cloud computing? The concept is that you are not as reliant on your personal computer, but your applications and data are kept somewhere in the internet “cloud”. So for instance, I use google calendars and gmail for several things. All my calendar data is stored with Google. There are several backup services that work on the concept of online backups. This is a variation in a sense, for all of them you are relying on a server somewhere online to be where your applications or data are stored. Of course, I can hear it now, “I don’t know if I like that idea”. Yes, there are a lot of risks. Recently Charter Communications has been in the news for losing the contents of 14,000 email accounts. That should…

Making sense of the different versions of Vista
Microsoft Vista is now out, the next version of Windows, successor to XP. While Windows XP will continue to receive updates into 2014 there are many that might be eager to upgrade and move to the latest greatest. (Note to those: Service Pack one may be en route THIS calendar year, so unless you like to bleed on the edge…. you MIGHT hold off until that’s out.) But those that do look at getting Vista are met with a dizzying array of choices.

Rsync for easy (and quick) backups
I’ve got to say, I haven’t spent ENOUGH time with rsync to really be fluent in how I could put it to use…. A week or so ago I was reading this list of essential Linux software by a guy that moved from Mac OS X to linux because he detested the DRM that was being shoved down his throat. Anyway, one of his essentials was rsync for backups. Which got me thinking. Why didn’t I use rsync for backups. At one point in time I used unison, but for some reason had stopped and was in need of reorganizing my home backup strategy anyway. I found a few interesting approaches.

OpenOffice.org security update
Version 2.0.3 of OpenOffice.org has been released. It includes quite a few bugfixes, including three security related fixes. The security vulnerabilities were apparently found in an internal audit. One of the improvements in 2.0.3 is an integrated update check, to be able to check for available updates directly from within OpenOffice. I think this is an important area to be improved.

Preparing for disaster recovery – system change log
There are a lot of elements to a good disaster recovery strategy…. knowing where offsite backups are located, keeping the offsite backups fresh. Knowing where any ON-site backups are. Having a plan for quick access to replacement hardware. One that probably is easily overlooked is very low-tech. That’s a system log. I don’t know that this isn’t a BAD idea for any system, but certainly is a good idea for servers and other “mission critical” systems. (In thinking about my desktop, this kind of log wouldn’t be bad….maybe a bit obsessive with a desktop, but…. I think I’ve messed it up more times than it’s spontaneously had problems…) So what am I rambling on about this time?????

Mondorescue manually restoring from an afio.bz2 file
For several years now, I’ve used Mondorescue as a backup solution for those customers with a Linux server. It makes for a nice, easily scriptable backup that can go ahead and burn to disc, *(or tape or another pc….) My preferred way of doing this has been a full mondorescue backup to dvd (usually one or two discs) and a couple “incremental” backups each week. The client site handles swapping the discs as needed *(I’ve got reminder emails scripted) and they rotate through two sets of discs. Since mostly, these backups are kept onsite, once a month I burn a copy to move offsite.

The 2nd journey begins… Mandriva 2006 upgrade 2 – Part 1
I’m writing this from the laptop. Having run Mandriva 2006 without any real significant bumps for a couple weeks I’ve come to a point where I’m ready to take the plunge on the desktop. The desktop is my primary workstation. The laptop get’s occasional light use and is the one I’m more likely to play with when it comes to possibly losing configuration information or scripts (because I’ve got things copied to the desktop and server.)

Making backups simpler
Linux.com is running an article on easy automated backups with a new program called sbackup. Sbackup is a product of Google’s summer of code and is a GUI to pick and choose what to backup and when to routinely back it up. Apparently the project was also sponsored by Ubuntu. (I’d expect integration into their distro’s admin tools if not already then.)

Linux home office article part 3
Newsforge has the third article in their series on Best Practices for the Linux Home Office. The main highlighs in this entry are RAID and backups and disaster recovery.
