What gets backed up?

It depends a bit on how it is installed but typically only user data is backed up (Windows/Mac - /users/*, Linux - /home/*). CrashPlan is not meant to back up system files. If you want to exclude a folder(s) from backup, add _NoBackup to the end of the folder name BEFORE you install CrashPlan. If you add it after, it will be backed up until the name is changed and the older data in that folder(s) will remain in CrashPlan backups.



If you want to exclude any folders/directories (and its contents) from backup, add _NoBackup to the end of the folder/directory name and it will not be backed up. It is wise to do this before the backups start to ensure the folders are not backed up at all. If you add it later, the old backup of the folder and the data within it will remain but no new backups will be performed on the folder.
