There is a known issue with the 3.5.2 CrashPlan app restoring metadata on OS X.


Steps to recreate

  1. User backed up a file that had FileSystem metadata (CreatorCode, Label, etc) under an older version of the CrashPlan app (up to 3.4.1.)
  2. User then upgrades CrashPlan app to 3.5.2+ and restores that file

Expected result

File restores with all metadata intact.

Actual result

File restores with metadata altered, sometimes significantly. For example:

  • stripping labels
  • setting the file to be hidden from the Finder


CrashPlan app 3.5.2 running on OS X

Recommended solution

We are working to resolve this issue as soon as possible. As a workaround, files that are currently "hidden" can be revealed in the Finder through a Terminal command.

  1. Open the Terminal
  2. Type the following command and press Enter:
sudo chflags nohidden [Path to File]
  1. Enter your administrator password when prompted

If you are not sure how to type the path, an easy shortcut that can be used is to browse to the folder containing the hidden item in the Finder. Then, back in Terminal, type the first part of the command:

sudo chflags nohidden

After typing "nohidden", add a space. Go back to the Finder and drag the folder icon containing the invisible files into the Terminal window. The Terminal adds the path of the file. After dragging the folder icon into the Terminal, press the delete key once and add the following to the end of the line:


Your command should look similar to the one below. Press enter to run the command. When prompted, enter your administrator password, then press enter again.

sudo chflags nohidden /Users/john/Desktop/CrashPlanInvisibles/*

This example would make all items residing within a folder named CrashPlanInvisibles on your desktop visible.
