If the Backup Status Report or Device details screen shows 0 MB selected for a specific device, that device may not be backing up as needed. This article helps you troubleshoot such situations to resolve backup issues.
Backup Status report
Device details screen
Verify the device's file selection
Clear the device's cache
If you have remote or physical access to the device, clear the cache on the device. CrashPlan stores a cache of information about device backups. If this cache is corrupted, CrashPlan may incorrectly report the device's file selection as 0 MB.
Check filepaths and names
Verify that the capitalization of the filepaths and filenames in the file selection match. Incorrect capitalization can cause issues with backups.
