Missing UPD template disk from RDS deployment

I think I am missing the template UPD VHD from our 2012r2 RDS deployment

Existing users are ok but all new users are getting temp profiles. I looked in the share where the UPD disks are defined and it looks like someone has accidentally deleted the template disk.  Is there any way I can recreate this without disrupting the RDS farm?

I don't have backups of the location where the profile UPD's are stored

thanks
