However, a while ago the backups stopped working. She saw this error message: “Unable to complete backup. An error occurred while copying files to the backup volume”.
I googled around for it and saw this KB article from Apple, which wasn’t too helpful, as the only troubleshooting suggestion was a reboot (hmmm, sounds a bit like Windows). I tried doing that multiple times, and still saw the error message.
So, we tried a different hard drive. That still didn’t seem to work–same error message.
Basically, if you are seeing this error on time machine:
- connect your time machine disk drive to your Mac
- turn off time machine by opening the time machine prefs and select ‘none’ for the backup disk
- open up your console
- click on ‘system.log’
- click ‘clear display’
- turn on time machine by opening the time machine prefs and selecting your disk drive
- watch the system log for errors that look likeMar 9 12:14:14 computer-name /System/Library/CoreServices/backupd: Error: (-36) SrcErr:YES Copying /path/to/file/file.name to (null)
- remove those files
- restart time machine by repeating steps 2 and 6.
I am not sure how to fix the issue if you can’t remove those files. The files that were causing issues for our Mac were imap mailabox files from Thunderbird, so I just uninstalled Thunderbird and removed the mailbox files.
