If the Backup Status Report or Device details screen shows 0 MB selected for a specific device, that device may not be backing up correctly.There are a few steps you can take to determine the cause of the issue and ensure your backups start running again.
- Open the CrashPlan App
- Click Manage Files
Backups do not run if no files are selected.
- If needed, configure the file selection to include files and folders in that device's file selection.
Check file names and paths
The CrashPlan app may fail to detect files on your device if:
- The files are on an external drive that is no longer connected
- Files have been renamed or moved to a location that is not part of the file selection
- The capitalization of file names and paths have been changed.
Take a quick look at your files and folders on your device to ensure that nothing has changed.
(Mac) Check full disk access
Due to Apple's privacy restrictions for files and folders containing personal data in macOS Catalina 10.15 and macOS Mojave 10.14, CrashPlan cannot back up some files from locations like the desktop, Contacts, Photos, and Mail until you grant access to the CrashPlan app. To back up these files and ensure they show up in your file selection, grant full disk access in System Preferences on your Mac.
Uninstall and re-install the CrashPlan app.
If none of the above solutions apply, the application's cache may be corrupted. Uninstalling and re-installing the application will clear the cache and trigger a file verification scan.
