I have reformatted one of my 4Tb my passports. It’s not backing up. It’s been connected for 11 hours and nothing was completed. I’ve had this issue now with 3 4Tb my passports over the last 3 years not to mention. My 2 mybook lives prior to 2010. Need assist. I can’t repair my MacBook until I back it up. Support was useless th we gave me rookie advice on how to set up time machine.
Time machine is the main backup utility for mac users offered by Apple. But sometimes the time machine is unable to backup your data and shows errors like Time machine backup failed etc.
Here are a few DIY fixes to resolve the time machine backup failure issue:
- Check the external hard drive’s file system.
- Check free disk space on an external hard drive.
- Check for junk files or other unwanted data as it might be causing problems.
- Check if the Mac software is updated.
- Try restarting your Mac.
- Check if the mac and the backup drive are connected to the same network.
By checking the above issues, you might resolve the time machine backup failure.
Hope it helps!
