I have a linux server with 3 disks of 2 teras each I want to know how I can do in this case to be able to save copies on the 3 disks since UrBackup only allows me to choose one path

Based on how UrBackup works today, you would have to consolidate those multiple drives by way of RAID or similar technology, in order to have the application see them as a single, larger storage repository.
