发明名称 Storage system determining execution of backup of data according to quality of WAN
摘要 There is provided a storage system providing a storage volume and being coupled via a network to a secondary storage system for storing a backup of data stored in the storage volume, the storage system copies data stored in the storage volume to the secondary storage system, upon receiving an instruction to create a backup; records the size of the data copied; predict the size of data to be copied in the future based on the recorded size of the copied data; records a usable bandwidth of the network at a time when the data is copied to the secondary storage system; predicts a usable bandwidth in the future based on the recorded usable bandwidth of the network; and predicts a time period required for copying data to the secondary storage system based on the predicted size of data to be copied and the predicted usable bandwidth of the network.
