摘要： The storage control apparatus of the present invention saves a table for managing a virtual volume in a pool and keeps the state of the table in the latest state. A first dynamic mapping table (DMT) that manages a first virtual volume is saved in a first pool. Upon receipt of a write command relating to an unused virtual slot from a write command issuing device, a first virtual volume control unit assigns an unused real slot in the first pool to the virtual slot and updates the first DMT. The first virtual volume control unit discriminates the validity of the received data and, in cases where “0” data are received, releases the assigned real slot, updates the first DMT once again, and discards the received data. In cases where the received data are valid data, de-staging is performed following a DMT update.

摘要： A DBMS performs a checkpoint process for maintaining consistency of data. A snapshot acquisition control program detects the checkpoint process externally to the DBMS and creates a snapshot in an external storage according to the timing of the checkpoint. Correspondence between checkpoints and snapshots is maintained in a CP-SH correspondence management table to make it possible to restore in a short time data at the time of an arbitrary checkpoint.
