A costumer is using an HP StoreOnce solution that is configured to use a virtual tape library. Which other configuration can the costumer implement on the StoreOnce solution?

RDX (Removable Disk Exchange) is a separate removable cartridge-based backup technology and is not an emulation or configuration mode supported within the HP StoreOnce platform.

HP StoreOnce does not emulate optical jukeboxes; its emulation capabilities are focused on tape library and disk-based backup targets, not optical media devices.

Business Copy is an HPE feature associated with EVA and MSA storage arrays for local replication and is not a configurable data mover option within the StoreOnce backup appliance.

HP StoreOnce is a disk-based backup appliance that natively supports multiple backup target types within the same device, including VTL for tape-emulation workflows and NAS shares (CIFS/NFS) for direct backup to disk targets. Configuring NAS backup to disk targets allows backup applications to write directly to StoreOnce as a network file share, complementing the VTL configuration without requiring additional hardware. This dual-mode capability is a core feature of the StoreOnce platform.
