Disaster Data Recovery and Your System - Work

What kind of plan needs to be used in a work setting to safely protect your data from hardware failure and viruses? It is a similar process to a home backup but on a much bigger scale. Many of the same methods are used but a greater storage capacity is usually needed.

In our school setting, all user accounts are stored on a server. Even teachers and staff who use laptops have their documents synchronized to a server. So, in most cases, the servers are the main thing to backup. These servers will host things like e-mail, blogs, calendars, library catalogs, and student information systems, as well as all teacher and student files.

For both Mac and Windows servers there are some solutions for backup software. EMC Software's Retrospect is a good piece of software that has both Mac and Windows clients. This software is installed on one machine and other machines on the network have client software installed. The main installation connects to the clients and backs up the desired data. It will backup SQL databases and e-mail (Exchange) servers. Usually, this server is connected to a tape drive, a packet drive, or other storage device.

Like a home user, some of this data might need to be backed up outside the building. Student information and financial data can be backed up to a DVD on a weekly basis and stored in a vault or somewhere else off site.

A third option would be to backup the data using online methods. Again Mozy's business version, Mozy Pro, would work. The software is priced based on the number of servers and storage space required.

This method requires more work by the administrator. Not only does one need to check on the status of the backups, but they need to make sure each server is connecting to the main server properly, and they probably also need to change tapes in the backup drive.

Disaster Data Recovery and Your System - Personal

There are many methods and philosophies on backing up your data. These may differ between home and work but the quest is the same...protect yourself against a disaster, and, if a disaster happens, to be able to recover your files.

My philosophy is simple. Backup your data in more than one place and keep those backups in different locations. Backing up to a computer or drive in your home or place of work will not help you if a fire swept through the building. Keep at least one backup set off site, either on CD, DVD, or online.

At home things are much simpler than a work environment. Depending on the platform you use for computing (Windows, Mac OS, Linux) the method and utilities available for backup and protection are different. Most backup software will require an external drive connected by firewire or USB, as well as a computer with a recent operating system, probably Windows XP and up and Mac OS X 10.4 and up. First, come up with a plan for the backup. Ask yourself, what do you need to backup and what tools do you have or can you afford so you can backup adequately?

At home, I use a Mac. Within the Mac OS there is a backup feature called Time Machine. This backup software will backup to an external drive or over a wireless connection to a Time Capsule, an Apple product that is a wireless transmitter with a hard drive built-in. For me, this software is adequate for backing up locally. It is fast and keeps many copies of documents so if I need to go back to a previous version, it is easy to do so.

For a Mac user, there are not many backup utilities available. Aside from time machine there are various disk cloners out there that will copy your hard drive contents to an external drive. Many of these are free, including Carbon Copy Cloner.

Windows also has a built-in backup program. You can use this program to backup to a floppy (probably not a good solution), a flash drive, a CD, or an external drive connected to your computer.

For Windows users, there are some free and low-cost solutions available. Cobian Backup is a free solution that supports both local and remote backups. Cucku Backup is a "Social Backup." It will backup your local drive to a "friend's" computer. If you are both people running the software you can backup to their computer. The files are encryped and the other person cannot see your files.

To backup to a remote location, both Mac and Windows users can use a program like Mozy. This will backup your files to the Mozy servers in different parts of the country. It is easy to use and you get unlimited backup space for only $4.95/month. This is the second part of my backup method at home. Another home online backup company is Carbonite.

In both the local and online backup methods, the user can schedule regular backups. After the initial setup, which only takes a few minutes, the user just needs to check that backups have been completed. It is pretty much a hands off method.

I have decided to try and post from my iPhone. How often will I use this feature? Probably never but it is cool to have that option.

How Important Is My Data?

Good question. To date, I have never lost any significant data (knock on wood). What can I not live without personally? We don't keep a lot of documents on our computer. We do our taxes online but have printed copies. We have a few spreadsheets and documents but nothing we cannot live without. Photos are another story. We have about 2500 photos of our kids and events over the last 4 years. We did have some of them printed and put into albums, books, and calendars and some are posted on our web albums but a majority of them on the computer only. While I could live without them, I prefer not to.

Professionally, what can I not live without? Everything. In my job as Director of Technology, I am responsible for data for the entire district including student data, financial data, alumni data, and student and teacher files. Lots to worry about. Even if my laptop were lost I would be missing files from the last 10 years that hold passwords, account numbers, instructions, PowerPoint presentations, and more. I definitely do not want to lose these things.

I take steps to protect my data both at home and at work. At home, I use a Mac and use the Time Machine program to back up to a hard drive elsewhere on my home network. I also use Mozy online storage to back them up off-site. If there were a complete disaster and I lost my computer and everything else in my home, at least with a new computer I could recover my files.

At work I also take steps to backup and protect. My laptop has a portable account so every time I am at work the files I have accessed and changed get backed up to a server. I also use the Time Machine software to backup to a server at another school. In addition, our servers are backed up to tape and online. Hopefully, if something happened, I would be able to recover the data. I have had hard drives go bad at school before and, thanks to backups and RAID configurations, I have been pretty lucky. I hope that streak continues...

Computer Predictions for Mike Bartels

What will computing look like in the future? Well, that may be hard to predict. Computing and technology moves quickly. It was not that long ago that I was using a 128k external modem on a computer with 8 MB of RAM. Now we are using flat, multi-touch screens, wireless mice and keyboards, and carrying a multi-function machine that is part computer, part media player, and part phone in our pockets.

I think these things, along with the classes that we are taking now, give us a glimpse of what is to come in education. While one's philosophy about education may differ from another, there is no doubt that technology and education will become integrated.

I often wonder what my kids, ages 2 and 5, will be experiencing in school when they are high school age. Will they even need to go to a physical building? It is certainly possible that they will be able to receive a college degree fully online using interactive technologies that we use now, including video, blogging, and wikis. By then, these technologies will have evolved into something else but its origin will be in the things we use today.

At the grade school and high school level, students will still be in schools 10 years from now. They will probably be doing things more online like turning in assignments, taking tests and quizzes, and interacting with classmates, all from a small, thin machine. They will probably be able to connect this machine to a screen that is paper thin and can be rolled up and taken anywhere. Textbooks will be electronic. Students will be able to take their e-book on this small device and project it on to any surface and manipulate it using their fingers. Operating systems will be gone and an interface such as a browser or an iTunes type environment will be the way people access information on these machines.

How will this affect teachers and students? Well, traditional teachers, which every school has, will have to get on board or get out. I have some of these teachers in my schools now. Anything to do with computers is not necessary. Back to books and writing. That is what education in this country was founded on and we cannot go wrong with that.

I am from another camp. I don't think teachers and students should be totally disconnected but technology is certainly important if we want our society to move forward. We need to encourage our students to use the technology they are familiar with while showing them how to use it responsibly. We also need to try and stay ahead of the game when it comes to technology. Because of funding issues, our schools generally fall behind in this field. But, with technology becoming cheaper by the day, hopefully our schools will think this is an important part of education and try to catch up.

This will require a lot of training and discipline by teachers and students. If teachers cannot keep up, there will not be a place for them in education. It would probably mean the end of teachers who have taught for 30 years and have have never changed their approach.

Do I want this to happen, well yes and no. I think it is time for education to catch up but I hope it does not go too far. That connection between student/teacher and student/student is important in the social development of our children.

To prepare for these types of things, we discuss upcoming technologies in our Technology Learning Community at Messmer. We have not started for the year yet but I have a blog set up from last year showing what we discussed. We only met a few times but I posted more about technology in the blog than what we discussed in person. Most of this was based on books and articles that I read during the course of the year.

It is my job as Director of Technology to make sure my teachers are introduced to new technologies, ideas, and methods of teaching. I need to make sure I stay on top of things and present them in a timely fashion. We may or may not use these technologies in our schools but it is important that they know about them.

Computer History for Mike Bartels

My first computer experience was in high school. I was working at a factory in the late 80's and one of the engineers and I were talking about personal computers. He said he could help me build one for a pretty cheap price.

At the time, I was enrolled in computer programming courses in school. I took two years of BASIC and two years of independent study in Pascal. I was working on Apple IIe and Apple IIgs computers. I even went to programming competitions.

We put together my first computer. It had a 13" monitor, a 5 1/4" floppy disk, and 256 MB RAM. It ran DOS and a couple of years later I upgraded the RAM to 1 MB and installed Windows 3.0.

I was able to do my papers and print them out on my dot matrix printer. I also started playing games like Flight Simulator and various card games.

I decided to pursue music in college. It was my first love and, even though I liked computers, I knew I would not be able to handle the math classes so I decided not to pursue and education in computers.

While in college I started composing music. I went out and purchased my first Mac. I was able to hook up my keyboard and compose using Finale software. That was something I was not able to do with my Windows machine. After graduation I was experiencing problems with my computer. I didn't make much money so I could not afford to have someone look at it. So, I decided to fix it myself. That was when I first realized I might want to re-think my career path.

I did computers on the side for the school district I worked for and soon I was the technology coordinator and band/choir director in a K-12 school. I learned about purchasing, budgeting, researching technology, repair, and training. I was also able to us this technology in my classroom. I had students composing music, used the computer to create quizzes, and was able to demonstrate music techniques with video and audio that I was not able to do with a stereo. But, I was overloaded and had to decide what to do next.

I got married in 1998 and moved to Milwaukee the next year. After a year of working in the instrument sales business I took a shot in the dark and applied for a computer job. I got the job and have been here ever since.

Computers changed my life completely. It gave me a new career path and it has been very rewarding. At times I do miss teaching but computers and technology is where I hope to stay.

First Class Review

Well, our first class has finished. I learned about a couple of new technologies in this course and am already working on ways to incorporate them into our technology plan at school. We will be launching a social bookmark site this week full of educational resources for all grade levels and subjects.

I have also started working with our guidance department on creating a social network for our alumni. One of our counselors wanted an interactive site so recent grads can support current students. Originally the idea was just a discussion board but that evolved and they wanted something more Facebook-like. I showed them how Ning works and we are working on a plan to present to our administration.

I am now looking forward to our next class on how computers work. I already have a good understanding of what each part does but there are some things, like how operating systems work, that I would like to understand better.
