Devolutions Server Backup Configuration - Load-balanced, High-availability architecture
I was going through documentation relating to backups and was not able to find anything that calls out how backups are handled in a load-balanced, high-availability architecture where there are two web servers and two database servers. This doc mentions using a CIFS share if you have separate servers for app and DB.
I am not sure if it is necessary to have my backup share attached to all 4 servers or just on two of them (one web and one DB).

Hello,
As the two application sever points in fact to the same database (which can be setup as always on databases on the backend), it is only needed to backup the database and one of your application server.
Beside of that, it is also important to save the Encryption key on a safe / different location.

Thanks for providing those resources. So it would be safe to say that I only need to attach my share to a single application server and a single database server then? And then of course make sure to properly back up my encryption key in a different location. for proper DR.
Hello,
Well, I can imagine that if you have an HA environment on both the application and database sides, you already have some backup mechanisms in place. The Backup Manager is typically used when no additional backups are performed.
In my opinion, if another backup procedure is already in place (such as database backups or VM backups), using the Backup Manager would be equivalent to backing up a backup.
