Rich's Random Thoughts

A couple of years ago I wrote a blog post about how to create a family friendly internet setup in your home.  Given how quickly technology changes, I thought it was time to revisit the topic to see what has changed.

Being the father of five children under the age of 15 years old, and having 4 computers in our home along with a couple of iPod Touches, I’ve been experimenting with software & services over the past few years to try make my childrens’ experience on the internet as porn free as possible. After trying some commercial software for content filtering that ended up slowing down our 4 year old computer, and didn’t do anything to help on our iPod Touches, I have found something that works quite well on all the internet devices in our house (remember that no solution is 100% perfect not matter what the software vendor claims).  It not only works well, but once you set it up on your home router, you don’t need to install anything on the desktop computers or iPod Touches!

Drop Box synchronizes files between computers across the room or across the internet.  The service is free if you have 2GB of data or less.  For $10 a month you get 50GB of data storage.  I’ve used DropBox for several months now, and have to say that it works great.  It makes it much easier for me to quickly share documents between my Laptop (mac), my Work Computer (windows), and my Home Computer (mac).

Not only does it facilitate file sharing, but it also serves as an excellent backup system. While more expensive than Mozy’s $5 a month backup service, you do get a lot of extra functionality that Mozy does not give you.  DropBox works great on Mac, Windows and Linux computers, which means that it can be used on virtually any computer you own or can currently buy, including one of those cute little Net Books.

Another feature that some might find useful, is the ability to share sub folders with other people for collaboration purposes. As files are modified, previous version are kept so that if necessary you can revert back to a previous version of the document.  Files that are accidentally deleted can also be recovered, unless you manually purge deleted files.

I highly recommend DropBox for people who use multiple computers and need to share files between them.  Good luck!

I had an interesting experience at the end of the day yesterday. One of my Law Library colleagues looking quite distressed came into my office and said, “I think I just lost a VERY important file.” My response was, “no problem! Worst case we can restore it from backup.” That’s always my response when someone says they’ve lost a file – it usually calms them down and reassures them. She followed up by saying, “I just created the file today. Will it have been backed up yet?” Her face dropped when I said no. Our backups only happen at night, so a file created today would not yet be backed up.

So I started looking for the file. Sure enough, she had deleted it from the file server, so it didn’t go into her recycle bin. I tried doing a windows search (she’s running Vista Business Edition), and could only find a link to it in favorites, but not the file or a temporary file. Lastly I tried doing a Google Desktop search as we have it indexing her computer and her file share. It thought it found the file, but the link was dead (because the file had been deleted), but we could look at the full unformatted text of the file with the preview option. So we copied the text from the preview, and pasted it into a new Word document. I had one relieved customer. She had to reformat the document, but it saved her hours of work writing it from scratch.

So… Google Desktop is not only a great desktop search tool, but it can also help restore deleted files that have not yet been backed up!

As the systems administrator at the UVic Faculty of Law every semester I see one or two students who have lost everything… documents, pictures, music… Everything on their laptop computers. The look on their faces is unmistakable. They come to me looking for help. Unfortunately more often than not I have to deliver the news to them that they have lost all their data. Typically the the data is lost because of a hard drive failure (a recent Google report seems to indicate that newer high density hard drives are becoming less reliable not more reliable). Recovery is sometimes possible (just ask my good friend Mike Binstead), but it can often be quite expensive ($1,000 or more) if the problem is severe enough that a hard drive recovery company needs to be involved.

The most recent student who came in to my office with a troubled look on her face, just had her laptop stolen, and did not have any of her data backed up. She lost everything except for things she had e-mailed other people (she uses a webmail program, so her e-mail was not lost).

Last week I heard another sad story from publishing company that I’ve been working with. One of their branch offices had a fire which destroyed all six of their computers. The person in the office I’ve been working with most closely didn’t have any of her data backed up and lost everything. Two others in the office had backups, but stored them at the office, so their computers and their backups were both destroyed (just because you back things up doesn’t make your backup system full proof).

I know a number of data loss stories from Hurricane Katrina… I won’t tell them here, but I’m sure you can imagine what happened to many people and companies who were not backing up their data, and keeping some of the backups stored off site.

The biggest complaint I hear about backups is that people feel they are a pain to do. I agree! Most backup systems are a pain. If a backup system requires human intervention on a regular basis, it is probably not going to work well. Up until recently I backed up my home computer by burning the Data to DVDs. I have enough pictures and videos on our computer now that it took 3 DVDs to back everything up. It was a pain to do, and as a consequence, I ended up backing things up once every two or three months … not very impressive for a systems administrator.

At the Faculty of Law we backup everything on our servers nightly using a little piece of software on the servers that backs all the changed data to a central server on campus. The next day, a copy of the backed up data is shipped to a storage location on the other side of the country. I sleep better knowing that if the Law School Burns down, all our data is recoverable.

I recently started using a similar system for my laptop and home computer to backup all the data. It is Wonderful easy to use service, and for up to 2GB of data it is Free! The company is called Mozy Online Backup. If you have more than 2GB of data, you can pay $5 per month to store Unlimited Data. I am happily paying $5 per month for my unlimited account. Mozy works on both Windows (2000/XP/Vista) and Mac OSX (the Mac client is currently in beta testing, but I am happy with it’s performance on my laptop). Here are the features I love about the Mozy backup service:

1. It requires no intervention to backup. Just setup an account, install the software, select what you want to backup, and then just let it run!
2. It backs up your changed files every 3 hours, and keeps different versions of the same document for 30 days.
3. It stores your data off site at a different location, so in the case of a natural disaster or fire, your backup will be safe.
4. It is cost effective. Free for up to 2GB (which will work perfectly for UVic Law students) and $5 per month for unlimited backups.
5. The data is encrypted before it is sent to the server so that it is secure while it is being transfered over the internet, and while it is being stored on the Mozy server.
6. Mozy just signed up General Electric as a customer, to backup their systems world wide. A nice vote of confidence in Mozy.

I encourage everyone who does not have a good, reliable backup system in place to take a hard look at Mozy for your personal backup solution. I’ll be installing it on the two computers are my parents house the next time I visit.
