A bug in a recent Adobe Creative Cloud update is currently deleting a folder on the root drive (Macintosh HD, by default) of Macs upon installation. This issue is affecting Backblaze users disproportionately due to the fact that the bug results in the deletion of the contents of the alphabetically first hidden folder on the root drive, which is often the folder ".bzbol" for Backblaze users.
Of course, if you are not a Backblaze user, the bug can still delete files within whichever hidden folder in your directory is first alphabetically, which may or may not have extremely undesirable consequences on your system. For some readers, the first hidden folder may be one called, ".DocumentRevisions-V100," the files within which are necessary for proper file version mapping and recovery functions within OS X. Whether or not there may be a solution that undoes the deletion (or rather, replaces these files) is still unclear. Adobe said they have stopped distribution of the update that causes this issue, which began with version 22.214.171.124.
Backblaze posted a video (above) showing the deletion of the files, but also shared a temporary solution, which naturally involves creating a hidden folder in the root directory that comes before the one called ".bzvol". They have managed to fit a small bit of humor into their fix, but they undoubtedly find little of this situation funny, given the impact it's had on their users.
To correct this, please do the following:
Open Terminal, which is found in Utilities under your Application folder.
Copy and paste the below command, pressing enter after:
- sudo mkdir /.adobedontdeletemybzvol
After you press enter, you will need to enter your Mac Admin password and hit enter to create the folder.
This should protect your .bzvol folder from being emptied by Adobe Creative Cloud, as the new folder is now first alphabetically.
**If the bzvol folder has already been wiped, you will also have to follow these steps after creating the new directory.**
1. Click the Backblaze icon and go to preferences.
2. Click the Settings button.
3. Check both boxes for the unplugged and plugged in internal Mac HDs.
4. You may receive a message that one drive will replace the other -- this will not affect your backup with this issue.
5. Click OK
This should resolve the bzvol error and allow backups to resume, as scheduled.
**If you have any hidden folders alphabetically before .bzvol, you may want to restore them from Backblaze.**
The latest 'beta' installer of the Backblaze software has been updated to create a folder named '/.aBackblaze/ at the root of your hard drive as a decoy folder. Running the latest installer will also prevent this issue, like following the above steps. The installer can be downloaded here: http://files.backblaze.com/
UPDATE: Apparently, Adobe has resolved the issue with a new CC release. Of course, this will not fix or reverse the deletion issues in any way. The new version will not, however, cause the issues to begin with for those that are lucky to not have been affected.
