摘要:
A disk array apparatus has a plurality of disks constituting a mounted RAID group and controls access from an upper-level device to each of the disks. The disk array apparatus also has a performance information collector for collecting a piece of performance-related information of each of the disks, and a suspected disk detector for comparing the pieces of information collected for the disks by the performance information collector among disks constituting a single one of the RAID group and detecting a suspected disk suspected of being abnormal in performance based on a result of the comparison.

Disclosed are a storage control apparatus, a storage control program, and a storage control method that collect the backup of storage data in units of generation at low cost.A storage control apparatus that creates a generation backup of a storage, comprising: a first copy section that creates a snapshot of at least one of all data stored in the storage at an indicated time point and difference data stored in the storage in an indicated time period; a second copy section that creates a mirror of at least one of all data stored in the storage and difference data stored in the storage in an indicated time period; and a controller that causes one of the first and second copy sections to copy all data stored in the storage and causes the other to copy difference data between generations stored in the storage.
