Apple Event: May 7th at 7 am PT
Since the OS update to 10.15.5, I've been getting failed TM backups (I have 2 in the apartment and they're both failing with the same error).
The message I get is "Time Machine completed a verification of your backups. To improve reliability, Time Machine must create a new backup for you."
Neither of my machines are actually backing up on TM, instead this loop of error/retry/error happens.
MacBook Pro 15″, macOS 10.15
This message is Apple's polite way of saying that your Time Machine backups are corrupted and unusable. This does occur a lot more often on Macs running the Catalina 10.15.x operating system. Apple has not provided a "fix" for this.
You will need to click Start New Backup to have Time Machine erase the existing backup for the Mac that you are using and start over again with a complete new backup of the Mac. This will take a long time.
You will then need to do the same thing with each Mac that displays the message below.
If you are saying that you are clicking Start New Backup and nothing happens or the same message appears, then there are other issues.......like a failing hard drive on the Time Capsule.......that will need to be addressed.
Agreed.... Symantec said they are looking into it and will post an update...
Cool. That’s what I discovered. It was happening with my 2 Network Drives, that I use for my MacBook Pro and Mac Mini...
I think it was more for them to see which one was going to cause the problem. However, even with everything off it's still coming up with the error.
DOH! It's now doing the same error when I try to backup over wifi :( Im going to wait for Symmantec to update the problem
Hi everyone there is still no fix for this problem. Symantec is unsupportive.
What a mess... https://community.norton.com/en/forums/norton-security-857-broke-time-machine-backup
Hi, try this link. Apparently there are hidden files. I had to Uninstall Norton on my MacBook Pro and Mac Mini.

Hi Lestat99, I ran the TM once more after removing all the Norton hidden files and the same message appear. Now I can't be sure if I should reinstall Norton for the time being.
OS 10.15.5 + Time Machine incompatibility
