How to Use Bitcasa Cloud Storage and Mirroring on OS X

I started using Bitcasa when I purchased my MacBook Air, and it’s slowly becoming my Dropbox replacement.

The Air comes with a small SSD (Solid State Drive). It’s lightning fast, but my old laptop had a 1 TB hard drive. I certainly didn’t want to carry a portable drive around, so I signed up for Bitcasa’s Infinite Storage while it was in beta for the low price of $49 for one year. (Infinite Storage is a lot more expensive now, but you can get up to 20 GB for free.)

Let’s take a look at how it works.


Bitcasa is billed as “Your External Hard Drive in the Cloud.” After you create an account and load the software, a drive appears on your desktop. It’s a cloud storage drive, so you must have Internet access to get to it.

You can mirror drives and copy files to the Bitcasa drive as backup or simply use it as storage. You can access those files on your iOS device or on your Windows or Mac computer.

Note: For the purposes of this article, we’ll be discussing how to use Bitcasa with the OS X platform.

You can also access Bitcasa from the Finder, as shown below.

Uploading Files and Folders

There are a couple of ways to send documents to Bitcasa.

  • You can select the Bitcasa icon on the right side of the top Apple menu bar and choose Send Files or Folders.

    Selecting Send Files or Folders in drop-down menu

    A drag-and-drop box appears. You can browse to find files to add or simply drop files onto it.

  • Or, you can click the Bitcasa icon on your desktop and select Open Bitcasa Infinite Drive. You can drag and drop files here at will.


My favorite feature is the ability to mirror drives and folders.

1. Right-click any folder on your hard drive and choose Bitcasa > Mirror This Folder to Bitcasa.

2. The folder will now be mirrored in Bitcasa, in a subfolder of the folder with the name of your computer.

The larger the files, the longer the upload will take. You could upload your entire video collection and photo collection if you had the Infinite Storage plan. Along with the free plan, there are also tiered levels of storage for monthly or yearly fees.

3. As soon as the mirroring is started, you are notified as shown below.

4. Once the mirroring is complete, the files appear in the Bitcasa Cloud. Any time you make changes to the files in this folder, they are automatically mirrored in Bitcasa.

The green check on the folder shows that the file upload and mirroring are complete.

Additionally, you can attach a USB drive to your computer and Bitcasa will ask if you want to copy the files on it to Bitcasa. This is a great way to have redundancy on your important data on USB drives, since they can fail like any other drive.
