Mozy has Nailed Remote Backups

Mozy has nailed it. I have been very interested in remote backup solutions for a long time for two reasons:

1. Everyone should do backups
2. Automated remote backups is the only way to go

My interest goes so far that I created a peer to peer distributed backup system in University (if you want to read my papers on it, check here).

Today, most people are getting sold on the ol' external hard drive unit with one click backup, backup to CD, or some other lame manual process. Manual being the keyword here. Nobody is going to remember to backup their stuff every time they change it. Lets say you edit a word document, are you going to be sure to back it up right after you're done? CD or DVD backups are the worst of the options because are you going to burn a new CD for a 1KB file? And what if you're house burns down? Then you've lost all your CD's and your external hard drive anyways.

Those types of systems are not for regular backups. A backup system must have the following properties:

  1. Automated - setup once, and don't think about it again
  2. Incremental - will only backup modified files
  3. Encrypted - it should be encrypted on the client before being sent for the best security
  4. Remote - this one may be questionable to some, but I think it's essential

The location one is important due to fire, robbery, etc, but is also important for laptop users since they may not be at home.

I'm trying not to stray too far off topic here, but I wanted to provide background as to why I think I have found the new winner for backups. And the winner is: Mozy . It has all of the required properties in a nice easy to use package, but the best part is you get up to 2 GB free! There are other solutions out there, but free is not in their vocabulary.

For me, encrypting the data before transmission is the critical part.

Good point, I should have mentioned encryption, but Mozy takes care of that as well so presumably they can't even read your data as long as you use your own private key. They give you the option of using theirs or making your own, but using their key would mean they could access your data which I would strongly discourage.

I would like to use my own key, but I don't know how to do that. In the Mozy FAQ it says it should be a 448 bit Blowfish key but I have no idea what such a key looks like...

Any suggestions?

Travis Reeder said...

When it asks what you key you want to use, your own or theirs, choose your own, then just use a secret word or phrase that you will remember so you can decrypt your data when you need to recover it. I "think" it must generate the blowfish key from that secret key word/phrase, but don't quote me on that.

Johan said...

I see, that makes sense.

My worry was that I would have to enter a 'real' Blowfish code and I don't know how to compose such a code.

Thanks for the help, I will try this out whenever I have time for it.

Note to self: Never use IDrive-E and warn all my online friends not to either.

Leio, I hope that spam comment for idrive didn't make you go try it. Didn't even notice that comment until you posted yours. What's wrong with IDrive?
