Has anyone figured out how to copy one Ubuntu server A using restic restore backup to Ubuntu server B ?
Hi @danieljamesbertrand and welcome to the Restic community! 
I kindly ask you to utilize the forum search before opening a new thread. This topic has been discussed various times over the years and there are a couple of threads where you could ask further question in the case none of the information there could help you solve your issue.
