Hi All I have sort of the same problem. But my drives are connected through a SAN. So small flies in LANFree Backups are an issue. Is there a way to avoid this interrupted stream issue? It sounds like a terrible waste to have several LTO-1s with fibre attachments and HBAs and what nots to have to always rely on disk pools.
