Time Machine fails to back up

Time Machine fails to back up Errer.

The OS is on a Thunderbolt3 drive.

I tried all the things you should check like restarting the Mac checking for updatesI everything is up to date ,i have a Seagate 6 tb drive with four Partitions. are on there. I have tried other Partitions on there and another hard drive i have .And it still comes up with an errer failed to back up.

I also have another Thunderbolt3 drive with a different version of OS and the internal one both back up on the seagate drive .I have not tried backing up on those two partions.What is wrong is there something wrong with the thunder bolt drive or what?
