We're buying a new server and are switching to a virtual environment. We want to have one physical server as a host containing several guest servers. We're a small organisation and we know that ideally we should have more redundancy, but it's not an option. Some vendors recommend VMWare, some Hyper-V. Some recommend Backup Exec (V-Ray edition), some Veeam. Since some vendors gave contradictory information on some aspects of possible combinations of hypervisor and backup program, I'm asking here.
Can we backup directly to tape or external disk, without a separate physical backup server in between, having the backup program installed in either guest or host? (we prefer not to have a separate physical backup server)
