Error long create failed! max 2*255 bytes

I am running windows 11 on my server and the target for the backup is a share on my NAS WD-EX4100

This error is now popping up

Is this just something that is the way it is? or can I change a setting on the NAS to fix it?

Thank you

George

(err_long_create_failed). The filename, directory name, or volume label syntax is incorrect. (code: 123)
UrBackup Server has trouble storing files to backup storage with the maximum file name length it was compiled with (255 UCS-2 code points/UTF-16 with max 2*255 bytes). There might be issues when backing up files/folders with long file name.
