Restore can be done by reversing the copy direction of QuickOPC and executing OPC.
Although a restore is executed with OPC, only the data that has been updated since the previous QuickOPC is copied. Therefore, in copy using QuickOPC, not only a physical backup but also restore is completed in a short period of time.
By performing OPC for restore, any changes made at the primary volume after the previous logical copy will be rolled-back (overwritten from the secondary volume data). Consequently, any and all changes made to the primary volume after the previous logical copy are discarded and lost following OPC for restoration.
