Backups never finish

I am getting an interesting issue. When I try and backup MAC or Ubuntu servers it seems the full file backups start. After a while I get an error that Creating symlink to a path gets an Unknown error 524 (errorcode=524). I am running on an Ubuntu 22.04 and mounting S3 storage through an AWS storage gateway server as an NFS mount. With direct attached storage I dont get this error. Has anyone seen this before?
