The above list is user editable as long as backup quota is observed. You can visit the following link for a step by step instruction on how to check your current quota usage.

Verify a file is set to be backed up

You can verify that a file is set to be backed up by doing the following: 

  1. From your /Applications folder open the CrashPlan.app application.
  2. From the Home screen click Manage Files to view the file selection.  Any files and directories with check boxes next to them (h) are being backed up.


  3. A checkmark indicate that the entire contents of a folder are backed up, a dash "-" indicate partial content of a folder are backed up.
  4. To reduce backup disk space usage, uncheck files or folders that do not need backup protection.
