Can't backup Time Capsule

I have been requested to start a new backup on Time Capsule, however the backup took a long time and was never completed. I tried many times, and even restarted the Time Capsule, still it doesn't work, please help.

Unfortunately, the Catalina operating system has broken Time Machine for a number of users. In order to try to get things going again, you are going to need to perform a manual procedure to completely erase the Time Capsule disk and then try to run another backup.


On your MacBook Air.......

Open AirPort Utility (Finder > Applications > Utilities > AirPort Utility)

Click on the picture of the Time Capule

Click Edit in the smaller window that appears

Click the Disks tab at the top of the next window

Click Erase Disk





When you click Erase Disk, a selection box will appear to allow you to choose the type of erase

Select the Zero Out Data option

Click Erase





The erase procedure is going to take a very long time.......up to a day or two. Let the process run until it completes. The Time Capsule will blink amber during this process.


When the erase procedure has completed........Restart your Mac and try to run another backup. This will also take a very long time.


Report back on your results.
