Disaster preparation 101 — Data backup

Paul

In this one I will talk about Disaster, it happens to all of us from time to time. A fire, a earthquake, a stolen laptop or any number of ways. So what happens to your data, is it stored on the laptop? Is it important very sensitive data? Could you get fired if you lost that data?

[ad#ad2-right]These are all questions you must ask yourself when you have laptop. How do you backup your data or even do you have a backup? Having seen this with my own clients, I must wonder if there are people out there who just don’t care. I had a client the other day who gotten a virus and this was a really mean virus. Deleted some very important files when you tried to clean the virus out. She called me in a panic because she couldn’t load up windows? I asked if she had any backups, she said “what’s a backup” . So I sat there discussing this with the client for over 20 minutes. Finally she started to understand, she said she had the OEM Backup DVD but nothing else. She also said she needed help with getting data off the computer. I told her that I would be able to come the next day and I was lucky the virus didn’t do anything else to her data. We were able to retrieve the data from her system. That is where I start my rant , Why would anyone not have backup of there most important data?

So How do you backup your data? This is controversial and somewhat depends on how much people want to spend to keep there data safe and not loose pictures or music. There are several ways to do it, each way has it’s pitfalls or short comings and requires a little more effort:

Kinds of Backup

Hard Medium – DVD, CD, External Hard drive

Although,  The hard medium is usually used that doesn’t mean you can have a backup other than hard.   Here are some ways to back up on the internet.

Internet Medium:

  • Jungle Disk — Provides online storage through the Amazon s3 service.   Only pay for what you use.   It works well with most Operating system.  I’ve used it on Vista so it is really nice.

  • Carbonite Online backup –Another good Online storage.

  • Some Other Online backup — Here a list from Amazon to better help you find the type of software that you might need.

These are just a few options, if you want to look for other you can.  The important thing to do is BACKUP because if you need some data that gets wiped or destroyed.  You will be kicking yourself for not backing up.

Microsoft Windows Server Service Vulnerability (MS08-067)

Paul

A vulnerability has been identified in Microsoft Windows, which could be exploited by attackers to take complete control of an affected system. This issue is caused by an error in the Server service that does not properly handle specially crafted RPC requests, which could be exploited by attackers to crash an affected system or execute arbitrary code via a specially crafted request.

On Windows Vista and Windows Server 2008, the vulnerability is only exploitable by authenticated users.

Note: This vulnerability is being exploited in targeted attacks.

This was just discovered and needs to let people know. I will do more research on it and maybe come up with a way to fix the problem. According to my sources there is a patch that will fix the problem!!

*UPDATE*
According to Microsoft:

This security update resolves a privately reported vulnerability in the Server service. The vulnerability could allow remote code execution if an affected system received a specially crafted RPC request. On Microsoft Windows 2000, Windows XP, and Windows Server 2003 systems, an attacker could exploit this vulnerability without authentication to run arbitrary code. It is possible that this vulnerability could be used in the crafting of a wormable exploit. Firewall best practices and standard default firewall configurations can help protect network resources from attacks that originate outside the enterprise perimeter.

Cleaning out the Prefetch Directory!

Paul

From time to time you will need to clean out the Prefetch directory in Vista and XP.  Here is how you do it in Vista.  You first would need to boot into safe mode in Vista then you will log into Vista and go to:

[ad]

[C:\Windows\Prefetch Directory]

Having been using XP and Vista for the past few years, I’ve found that deleting all of the files in prefetch directory and letting them rebuild actually speeds up the system.  I got a feeling it has something to do with file corruptions.  After you go into the Prefetch directory and delete all the files.  You would then go into your Readyboost Directory if you are using Readyboost then there will be a Readyboost directory inside the Prefetch directory.  Deleting all the files in the Readyboost directory also will greatly improve performance of your system.  Don’t delete the Prefetch Directory or the Readyboost Directory, Vista won’t let you delete the Prefetch but will with Readyboost.  Deleting the Readyboost directory will prevent  Vista from using Readyboost and then you would have to restart the process of using Readyboost.

If you can come up with more ways to speed up Vista then by all means let me know!!

Calling all Geeks: Keith’s SysAdmin Meme

Now I’m call all you out!!

As you can see I’ve got Several people here who you don’t think would reply or even think about doing this.  I have a plan.  I want these people to tell their story about this memo.  I challenge them to actually post their responses on their blog or Podcast.  I want to hear your story about the old days.  I want to find out all about what people think or did to get into the IT profession!! I have this grand Idea to hear from the people and find out their story.  That is why if you do talk about the memo link back to me so I’ll know.

If you think you’re not a computer geek or a Sysadmin, I know better.  I am sure you have family or friends that you’ve had to work on their computer for some reason or other.  You have the skills even if you didn’t know it.  I want to know how you got into the IT Field.  I want to compile all this information to help people to get into the field and all this information is valuable to people.

I dare you Scoble, Mark, and the Co-founders to be the first to do it.  You know you want to!!!
