Error creating Symbolic links on network share from Ubuntu Server

I have urbackup server installed on a ubuntu server VM. The backup directory is a network mount from a samba share off of an Unraid FIle Server. What do I need to do to solve this error?

Thanks

What is the effect of not being able to create symbolic links. Will backups still take place?

I came across a post suggesting use of NFS shares instead of Samba. That worked just fine for me! For anyone checking this thread.
