Q: How do I find out what files CrashPlan could not back up?

On this page:


  • CrashPlan tells me that it is unable to backup some files. How can I find out what these file are?
  • History tab does not tell me what specific files, just tells me the number of failed files
  • The log to look for is called backup_files_log.
    Scroll to bottom (most recent) and Look for lines starting with a W - that means files did not backup.


From CrashPlan support page:


Go to /Library/Logs/CrashPlan

Note: If you have not already done so, see: How to make your Library folder visible in the Finder in OS X 10.9 (Mavericks) or later

Windows Vista/7/8

Go to C:\ProgramData\CrashPlan\log

Windows XP

Go to C:\Documents and Settings\All Users\Application Data\CrashPlan\log


Go to /usr/local/crashplan/log


Go to /opt/sfw/crashplan/log
