Message says Time Machine couldn’t complete the backup to Untitled. Unable to complete backup. An error occurred while creating the backup folder. Has been backing up successfully for over 3 years and this is the first time ever for this problem. Any suggestions or answers? macOS High Sierra 10.13.3, iMac 27", late 2013 machine.
Thanks
iMac, iOS 10.3.3, 10.13.3
This is standard fare on High Sierra. Time Machine is simply not reliable.
Are you backing up to a local disk or a Time Capsule (TC) on the network?
If this is a time capsule.. I strongly recommend you swap to a 3rd party backup software like Carbon Copy Cloner.
If you want to continue to use Time Machine and you are currently on TC then a local disk plugged into the computer by USB or whatever other port is available depending on the age of the machine.
However if your currently on a local disk.. then issues can also arise to local drives.
Is the drive actually untitled?
Try giving it a name.. short no spaces and pure alphanumerics.
Reconfigure TM to the target with new name.
If you are really hopeful and the glass half full type.. with a TC.. then firstly try to verify the backup.
Hold down the option key and select verify. If TM cannot find the TC mount TC disk first in Finder and try again.
Most important you have no 3rd party anti-virus, additional security software or adware on the computer. It will cause issues to network drives.
Thanks so much for your reply and suggestions. I am backing up via TM to a USB HDD 1TB LaCie Porsche Slim, and to the offsite service, Backblaze. I am not using any additional security software or adware. Anywhere I backup to is "Titled". Not sure if I am even backing up to my iMac hard drive and not sure where to look to see. I am a senior citizen and not that tech/pc savy, just know enough to keep my head above water. I did several restarts and a couple total shutdowns and this morning, it seems to be doing OK, and backing up automatically. I actually think this all started after I upgraded to High Sierra now that you mention it is not TM friendly.
Again, thanks for the input, I'll post an update later...
Time Machine couldn’t complete the backup to “Time Machine”.
