View Full Version : Is MobileMe iDisk syncing just Backblaze in disguise?

So, I was having some syncing hiccups with my iDisk and was chatting with a MobileMe support person. While waiting for my iDisk to re-sync everything, I got to talking about how the local iDisk is just a Finder directory designated as a device volume. (If you drag the iDisk to the Trash, it appears to want to Eject the disk. Could lead to data loss!).

Anyways, in a curious state I decided to use TinkerTook to show hidden files and folders. I noticed a folder in my iDisk called ".bzvol". Inside of which is a README.txt file.
WARNING: do not delete this directory or these files. If you do,
Backblaze will stop backing up this drive volume and also remove
any previously backed up files from the Backblaze datacenter. More
information can be found at https://www.backblaze.com/help.html

Wait. Backblaze? The third-party online backup company? Interesting. Backblaze data centers? IS our MobileMe data not stored on Apple servers? I did some googling, but I couldn't find any indication that Apple is using Backblaze technology. Although, Backblaze's site does mention "OEM Partners", so maybe they helped develop part of the iDisk syncing technology. I dunno.

However, another MobileMe chat person said this: Alright, as far as I know Apple does not use Backblaze for any internet storage. If there has been any changes in this department we have not been notified by Apple at this time.

No idea about Backblaze.

However, you can safely eject the iDisk in Finder without data loss.

Backblaze creates those hidden folders/files to tell it what to sync.

What I mean is, if your computer had previously had Backblaze installed, those files are littered all over your hard disk, including your iDisk folder. It has nothing to do with iDisk itself.
