ABSTRACT:
A storage apparatus conducts, in a protection period, data protection processing for protecting, in a third logical volume, data stored in a first logical volume by using backup data stored in a second logical volume, and suspends the data protection processing in a no-protection period, during which backup relative to the second logical volume is suspended, in the protection period. Then, upon receiving an external order for restoring the first logical volume to its state as of at a time not in the no-protection period within the protection period, the storage apparatus restores the first logical volume to its state as of at a time of the order by using the data backed up in the second logical volume and the data protected in the third logical volume.
