Abstract
To back up stored data of a storage device installed on-premise to a storage service provided by a public cloud more reliably and efficiently. A storage system according to the invention includes a storage device having first storage logical volumes (LDEVs), and a storage device having second storage LDEVs. When stored data of a first LDEV and stored data of a second LDEV are synchronized with each other, network conditions in a transfer path from the storage device to the public cloud and in a transfer path from the storage device to the public cloud are observed. The first LDEV or the second LDEV is selected as a backup source based on the network conditions.
