Ranked in these QuestionsQuestion Ranking
Pros
Pro Beginner-friendly defaults
The default configuration includes everything except for system files to be backed up. That also includes external USB drives. This will work for most people. It can, of course, be customized to each person's liking.
Pro No file size or traffic restrictions
There are no limitations of file size or amount of data you can upload. The $5/mo plan gets you unlimited cloud storage.
Pro Excellent restoration performance
Backblaze creates a zip file of all your files for you to download, thus decreasing the amount of data you need to download and increasing the speed of the download since it's one connection instead of multiple that need to be opened and closed for a list of files.
Pro Secure
AES encrypted files are transferred over a secure SSL connection.
Pro Download any backed-up files from any web browser
Some backup services like Carbonite require a client to be installed to restore files. Backblaze allows you to login and download any or all files from a web browser, meaning it also serves as an ad-hoc cloud storage platform.
Pro Users can order a physical copy of their data
You can have a flash drive or an external hard drive delivered to you. They cost $99 and $189 respectively.
Pro Allows quick access to the terminal system-wide
TotalTerminal is a plugin for Terminal.app. It provides persistent Visor Window which slides down when you press a hot-key.
Pro Quake style window show/hide
You maybe know or don't know Quake from Id Software. But this game had the best idea to hide/show a terminal window. Simply using full width but 26 rows. On show the widow slid down from top of screen. On hide it mode up to top edge of the screen until it disappeared. 2nd next best was the semi translucent background. You could still see through the terminal window while it was shown.
The same style is now available in TotalTerminal and iTerm2 (OSX Terminal replacement - no Terminal plugin).
Cons
Con No Linux support
There's no Linux client for Backblaze.
Con Pay extra to keep deleted files permanently
Additional $2/Month plus $0.005/GB/Month for files updated, changed, or deleted more than one year ago.
Con Backblaze does not support network (NAS) drives
If you use a thing like Drobo, Backblaze will not back it up.
Con Buggy
Con No longer under active development
Con Doesn't work on El Capitan with SIP on
Apple introduced a new security feature in OSX El Capitan, called System Integrity Protection, that, among other things, does not allow augmenting Terminal. While it's possible to turn SIP off (instructions on how to turn off SIP and get TotalTerminal working on El Capitan can be found here) it is not recommended.
