Back in December, online backup company Backblaze launched a private beta of its service for Mac users. Like its Windows counterpart, the Backblaze subscription service is $5 US a month (or $50 US a year) for unlimited backup space. Today, the company is officially launching its service for Mac users, along with an updated client, better support for external drives and enhanced recovery options.
Configuration and setup
Just like in the beta, Backblaze remains extremely easy to set-up and use. You just install the program (by default it will run in the background, though you can change this), enter in your e-mail address and password, and it will start backing up your files. The default setting has Backblaze running any time it finds an available internet connection. The backup process is constant and Backblaze stores multiple versions of a file for 30 days (so if you are frequently changing a document or spreadsheet, 30 days worth of revisions are saved to Backblaze).
If you want to remove Backblaze, the company has made the uninstall process easier and more intuitive. There is now an uninstaller built into the install DMG image, just double-click on Uninstall (right next to the install option) and you can take Backblaze off your system. If you trash the DMG, just download it again off the Backblaze web site for easy removal.
Backblaze won't backup your Applications (thought it WILL backup stuff in your User/Library folder, so many of your application settings will remain backed up), but it will backup your photos, movies, audio files as well as things like your iPhoto or Aperture database, various documents, and more. By default, .ISO, *.exe and *.DMG files are excluded from the backup file type list, but you can remove most of those extensions (*.ISO cannot be removed) if you want to backup that information.
The maximum single file size is still 4 GB, but keep in mind this doesn't mean your iPhoto or Aperture databases won't be safe. Those databases are actually just folders with lots of smaller individual files, that's fine. If you have individual files over 4 GB in size, those won't be backed up with Backblaze. You'll need to split the files into smaller segments or make alternate arrangements.
