I've gotten an early copy of B&R v8.0 Update 2, so I can apply this during a forthcoming planned maintenance window.
I run 2 Veeam B&R Servers, one of which I use for training & testing (t&t), which I've applied Update 2 to. We have a physical server which I use to store backups, and this has a number of Repositories set up on it on the production B&R server (still at Update 1). Until now, there has been only a local Repository configured on the t&t server, nothing set up on the physical storage box from there.
Yesterday I added the physical storage server to the t&t server and then set up a Repository on it. Alarmingly, this removed all the existing components installed by my production B&R server, so removing access to all the production B&R server Repositories on it.
I don't know if this is an issue with different components between Update 2 & pre-Update 2 servers, or that it's not possible to have 2 Veeam B&R servers set up with Repositories (even though each server uses different folder locations) on the same storage server.
I'd appreciate it if you could come back to me with an explanation of what's happened here, but also let me know if when I update my production B&R server to Update 2, this will then allow me to configure & use Repositories on my storage server from both B&R servers.
