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.

Claims4

Dependent claims

A storage system comprising:

a first storage device having a first logical volume;
a second storage device having a second logical volume forming a remote replication pair with the first logical volume;
and
an integrated management device configured to manage the first storage device and the second storage device, wherein
stored data of the first logical volume or stored data of the second logical volume is backed up to a storage service provided by a public cloud, and
when stored data of the first logical volume and stored data of the second logical volume are synchronized, the integrated management device or the first storage device selects, based on network conditions in a transfer path from the first storage device to the public cloud and in a transfer path from the second storage device to the public cloud, the first logical volume or the second logical volume as a backup source.
