SpidearOak gives you 2GB to start with. If you want to start with 3GB instead use this link.
Keep reading if you want to find out more.
So, first of all, SpiderOak is a web-based file hosting service "similar" to Dropbox.
You don't know what Dropbox is? oh well :-). You can have a look at the Dropbox intro video or keep reading..
Anyway, I've used Dropbox for a couple of years, until last month.
I was using it to share some files among different computers/phone and I must say that it has always worked well for me.
I always look for software that do things better but, in this case, I was even more encouraged to find an alternative when, last July, Dropbox made its license more restrictive.
As you can see from the last paragraph in the Wikipedia Dropbox criticism "In early July 2011 Dropbox revised their Terms of Service several times after first including language that appeared to give them an unrevokable license to any material uploaded. They subsequently clarified that language in response to the maelstrom of criticism and concern that resulted from artists and corporate users with confidential data."
The bottom line here is. Dropbox is still a good service but using it for confidential data MIGHT (I repeat myself, MIGHT) be risky.
The Dropbox staff can get access to your data. No one is saying that they do (on a regular basis at least).
So, SpiderOak, is a good and safer alternative to Dropbox.
Safer because SpiderOak based their entire architecture on a zero-knowledge policy and encryption.
I've already installed it on three Ubuntu boxes and my Android phone and I can guarantee that is fast, easy to use and has a nice GUI.
As you can see from the screenshot, it can be used to backup, synchronize and share data.
Another great thing is that you can get up to 50GB of space for free (with a refer-a-friend program).
There are two huge differences between the SpiderOak and Dropbox refer-a-friend program:
1) SpiderOak gives you 1GB per each friend (not 250MB);
2) SpiderOak gives BOTH of you that extra GB (not the referrer only like Dropbox).
So, for example, this is my SpiderOak referral link. If you subscribe to their service trough that link you get 1GB extra as well as me. That makes you start from 3GB rather than 2 only...
It's good for me, it's good for you. I like it that way... :-D
It's also cross-platform so you can enjoy it on Linux, Mac, Windows, IOS and Android.
You can add as many devices as you want.
Under Ubuntu Lucid (and probably others similar as well), if the "Launch SpiderOak at Login" option does not work for you add it manually:
Preferences -> Startup applications -> Add .
Name: SpiderOak (or whatever you want)
Command: /usr/bin/SpiderOak (which is the result of "which SpiderOak")
Comment: Online backup/sync solution (or whatever you want)
Once again. Here is the link to open a 3GB SpiderOak account.
That's all for now. Hope you enjoy your new free sharing service.
