Airport Time Capsule not working

Hold down the option key on your Mac while you click on the Time Machine "clock" icon at the top of the screen

Click on Verify Backups

The process might take anywhere from 10-60 minutes or more depending on how much data is stored on the Time Capsule hard drive. Let the process run until it complete or you receive an error message.

Post back on your results. If an error message appears, please post back with the exact message that you see

You can check on the progress of the process from time to time by holding down the option key and clicking on the Time Machine clock icon.

Let's make sure that your Time Capsule is currently selected as a backup destination for Time Machine backups. To do that......

Click on the Time Machine "clock" icon the top of the Mac's screen

Click on Open Time Machine Preferences

Click on Add or Remove Disk

Check to make sure that the Time Capsule disk.......likely named "Data", unless you changed the name of the drive......is selected as the current destination for Time Machine backups

Close the windows

If yes........

Power off the Time Capsule by pulling the power cord from the back of the device or from the AC wall socket

Wait 20-30 seconds

Power up the Time Capsule again

Restart your Mac

Try to run the Verify Backups check again

Report on your results

There's a box that says

backup disks

DATA..........

Then that tells you that DATA (the Time Capsule disk) is setup as the backup destination.......and there is another issue that is preventing backups from occurring.

Then, what do I click?

No, close the window(s).

Also, there is a orange blinking light on the front of my time capsule- does that mean anything?

Did this just start, or has the light been blinking amber all along?

Open AirPort Utility on your Mac...........(Finder > Applications > Utilities > AirPort Utility)

Click on the picture of the Time Capsule, and another small window will appear

Look for a listing of Status, and click on the small amber dot there. Another window will open up with a message. Post back with the exact text.

That message might provide a clue on why backups are not running. We'll see.

Next item......your profile indicates that you are using operating system 10.14.x (Mohave). Is the Mac still running Mohave or have you installed the newer 10.15.x (Catalina)?
