For those not in the know, SpiderOak is a decent alternative to Dropbox. It provides several useful features (some not present in Dropbox):
- SpiderOak Hive: A Dropbox-like folder
- Historical versions: All historical versions of a file are available indefinitely. (With a free Dropbox account, historic versions are available for 30 days only.)
- Strong security model: SO encrypts the files on your computer and doesn’t know your password. Thus it stores on its servers only long strings of encrypted bits that it cannot decrypt (nor the Government nor the NSA). The downside is that if you lose your password, you lose your data. (This is unlike Dropbox, which sends the data via an encrypted connection but stores the files in plain form on its servers.)
SpiderOak now organizes another promotional event in which it generously gives away GBs of free storage. It is called SpiderOak University. It features a series of 10 quizzes, and for each completed quiz you get 1GB in additional free storage. If you answer correctly all the questions in a quiz, then you’re in for 2GB of free additional storage. If you do the math, you could get from 10 to 20 GB just by spending a couple of minutes filling out the quizzes. If you want to get all the quizzes right, then you should follow the video classes available on their website. I don’t know if the SpiderOak University has a time-frame limit.
Additionally, you may get an additional 1GB (and offer me another 1GB in the process) if you created your SO account using my referral link. This is part of the traditional SpiderOak Refer-A-Friend program.
