N clients in the same pc, with different configurations and different servers

I have a linux data server that I need to backup to a cloud urbackup server and to a local urbackup server.
The data to backup to the cloud backup server are relative only to the works in progress.
The data to backup to the local server, instead, contains all the data archived in the linux server.
I woud like to have a way to start n urbackup clients, each with his own configuration file, so that each urbackup client may backup different sets of files to different urbackup servers.
