What To Do: If you were not running Adobe Creative Cloud on the Mac or did not update to Adobe Creative Cloud v188.8.131.52, you have nothing to worry about.
If you did, and you received the Backblaze bzvol pop-up alert, you’re in luck because the file that was deleted has been re-created by Backblaze.
Backblaze backups were in jeopardy during this event.
If you were not running Backblaze or did not receive this alert, Adobe Creative Cloud may have deleted a file or folder on your computer.
If you do see empty folder and have a local backup, or another backup system, you may be able to restore that data from them.
If not, you may want to contact Adobe for any help on this issue.
On February 11th, Adobe released an update to Creative Cloud (v 184.108.40.206) which, as they put it, “…in some scenarios the application may incorrectly remove files with user writeable permissions from the system root directory.” You can find their release notes here.
This meant that if you were an Adobe Creative Cloud customer on Mac with auto-update turned on (or happened to download that version), as soon as you signed in to Creative Cloud, files from folders within your root directory could have been removed.
Why Was Backblaze Involved: Backblaze keeps a hidden folder called .bzvol at the top of each drive we see connected to your system.It helps us keep track of your hard drives and keep them backed up.It’s difficult to tell exactly which data may have been removed, but you can open the root directory on your Mac and try to look towards the top for any folders that are empty.This would have occurred to only one folder (that we know of) so the top-most hidden folder or the first folder with a space as the first character would have been affected.We typically saw this occur to the user’s top-most (when alphabetically sorted) hidden folder, or to a folder that had a space at the front of its name (a semi-common practice to force a folder to always appear at the top of the list).
That update of Adobe Creative Cloud has since been pulled, and version 220.127.116.11 is available and is supposed to offer a fix.
