Question: Time Machine Fails

I am running MacOS 10.13.2 and have finally decided to start using Time Machine for backups. However, I cannot seem to complete the first backup! The backup starts and runs for a while and then I get the message "Backup Failed - Time Machine couldn't back up to <name of my disk>".


I have a Macbook Pro (Retina, 13-inch, Early 2015) and a USB-connected WD My Passport Ultra 1TB as backup drive.


After each attempted (and failed) backup it is no longer possible to unmount the disk. If I try it says that some "The disk <disk name> wasn't ejected because one or more programs may be using it."


I have tried a lot of different things:

- I have rebuilt the Spotlight index, tried turn it off and on globally and on the disk.

- I have erased the disk, tried First Aid (in disk utitility) for both the external and the internal drives. I have done these things at multiple times.

- I have also tried force ejecting the disk after a failed backup. Then connected it again and tried again (without deleting the failed backup file .inProgress). After a few attempts I have usually managed to get the backup running again, but only for a while. The closest I came with this methods were a few gigabytes away from finish, but at that point the amount that is left to backup is just counting up at the same time as the backed up amount. For e.g. it can say Backing up 2.4 GB of 5.0 GB at one time and a little bit later Backing up 2.8 GB of 5.4 GB etc.



I am at a loss! Also, I believe that the failure to unmount the disk after a failed backup has something to do with spotlight. If I try to delete the failed backup file from the disk I get the message: "The operation can't be completed because the item ".spotlight_repair" is in use."


Any help on this issue would be greatly appreciated!

Make sure you erase the disk to HFS+ Journaled in Disk Utility GUID table.


It's best to start with a freshly formatted external disk every time you start Time Machine.


Also try turning Time Machine off. Rebooting the machine in Safe Mode (Hold down shift) when you hear the chime.


Then reboot again when you see the login screen.


Turn Time Machine back on and select the newly formatted disk. When formatting, format the root volume of the WD My Passport. To do that in Disk Utility click the "View" button top left of window, and choose show all volumes. Then select the WD My Passport and Erase, make sure it's GUID.

Thank you for your suggestions. I tried doing a backup both when booted in safe mode and again in regular mode (with a erasing of the root volume in both cases). But it still failed...


I checked the log and there was some files installed with Homebrew that stopped the process (it failed to copy these files) so I have tried uninstalling that specific program and I am now running the backup again to see what happens.


If you have any other suggestions I would very much appreciate that.

OK, I have checked the logs and I think I have narrowed the problem down. I believe it always fails when trying to copy files from /usr/local/ or /usr/


Last failure was:


SrcErr:NO Copying /Volumes/com.apple.TimeMachine.localsnapshots/Backups.backup​db/<NAME OF MY COMPUTER>/2017-12-29-105925/Macintosh HD/usr/local/texlive/2015/texmf-dist/tex/latex/seminar/semin​ar.cls to /Volumes/Backup/Backups.backupdb/<NAME OF MY COMPUTER>/2017-12-29-105925.inProgress/15E91B0A-F367-4968-A9​48-04FF05E7404A/Maci​ntosh HD/usr/local/texlive/2015/texmf-dist/tex/latex/seminar

I uninstalled Homebrew for this reason and now I think that I have to uninstall also TexLive to get rid of the problem. Does anyone know anything about the meaning of SrcErr:NO Copying? Does it have to do with permissions?
