My Time Machine backup stopped working. Says the disk "Untitled" is full but the Air Port says there's 2T available. It was working fine until today. Maybe something to do with OS upgrade? I've got a 6-core Intel i5 running 13.3.1
iMac 21.5″, macOS 13.3
Hold down the option key on your Mac while you click on the Time Machine "clock" icon at the top of the Mac's screen and select Verify Backups
The process will take 10-60 minutes or more depending on how much data is stored in the backup file. Let the process run until it competes....or... until you see an error message.
If a message appears, post back with the exact text to fhe message.
Please read carefully again to see that it does not say that Time Machine is trying to back up to Macintosh HD.
It says that Time Machine could not back up the disk "Macintosh HD" (which is your iMac) because "it" (The Time Capsule disk) is nearly full.
The laptop backed up because that backup was much smaller than the other backup from the iMac.
The bottom line here is that the Time Capsule disk is very close to full and it is time to erase the drive and start over again with a new backup of each Mac and move forward. It will not be very long before you see the same message about the laptop not being able to back up because there is not enough space.
If you do not want to lose all of the old backups on the Time Capsule.....(even though you will likely never need them. Do you really need backups from many months and even years going back in time?)......it is possible to connect a USB hard drive to the back of the Time Capsule and use the Archive function in AirPort Utility to copy all of the data on the Time Capsule disk over to the USB disk......before....you erase the Time Capsule disk.
Now, if your Time Capsule is 6-7 years old, that is about the time that the Time Capsule hard drive and power supply tend to start acting up. So, I would not look at the Time Capsule as a long term backup solution if is the case.
Here is the message:
"Time Machine could not back up the disk “Macintosh HD” because it is nearly full.
Delete some files on this disk and try again."
I also back up a laptop to this Time Machine and it backed up without a problem.
The Time Capsule disk is named "Data". If you are receiving a message that the Time Capsule disk is named "Untitled", I cannot duplicate that error to troubleshoot and find a solution.
I have powered off, powered on, restarted, etc two of my Mac and a Time Capsule a number of times, but it stubbornly continues to function just fine.
Perhaps another user can help out.
The simplest, cheapest, fastest and most reliable backup destination that I have used for many years is a simple USB hard drive that connects directly to the Mac.
Unfortunately, Apple discontinued the Time Capsule 5 years ago, and in most cases no longer offers support for the product.
Why does it say that it is trying to back up to to my "Macintosh HD" and not Time Machine on my Air Port
Not sure why Time Machine thinks the disk is full when it shows that 1.9T is available
If the Time Capsule is not a viable long term solution, what is?
Time Machine couldn't complete backup to "Data"
