The main reason is that other apps I use also rely on Dropbox. While I’ve started using SpiderOak, I haven’t entirely given up on Dropbox. Another feature is that in addition to backing up your data on the “cloud,” you can also use the desktop version of SpiderOak to sync between hard drives and flash drives. Also, rather than having a single “My Dropbox” folder, you can select any existing folder to be backed up by SpiderOak. For example, you can opt to forego instant backing up and instead have SpiderOak backup during the night, when it’s less likely to borrow processing power from other applications.
The other significant difference is that SpiderOak offers a wider range of features, trading Dropbox’s elegant simplicity for greater control. Even SpiderOak itself has no access to your unencrypted files, something SpiderOak calls its “zero knowledge” policy. That means it’s all but impossible for anybody other than yourself to access readable versions of your data by hacking into SpiderOak. Most relevant here, SpiderOak encrypts the files on your computer before uploading them to the server. Like Dropbox, SpiderOak offers a free 2GB version, from which you can upgrade all the way up to 100GB for $100/year ($100/year only gets you 50GB at Dropbox).ĭespite these similarities, there are several significant differences between Dropbox and SpiderOak. Like Dropbox, SpiderOak works on multiple platforms-Windows, Mac, and Linux, as well as Android and iOS. Like Dropbox, SpiderOak automatically backs up files to the cloud, and those files can be accessed from many other devices. Combine this security lapse with Dropbox’s default encryption system, which, as Dave Parry argues, makes it possible for your files to be accessed by a third party via a backdoor, and some of us ProfHackers have begun considering more secure alternatives to Dropbox. Recently, however, Dropbox has suffered from some privacy issues, most recently a programming bug that left every user’s Dropbox completely unlocked for a four hour period. The writers at ProfHacker have often recommended Dropbox as dead simple way to backup and share documents across multiple devices and users.
