Additional context
At the company i'm working for, we are exploring the possibility of dockerising veeam server (for which we are paying licences) on a linux container or at least a hybrid solution where we have a VEEAM client dockerised and a Veeam Server on windows.
And I stumbled upon this github repository.

However, the purpose of this project is not clear and doesn't seem very active.
Is there any link you can direct me to ?
