be copied from the T-VOL to the S-VOL. Restore, the part of data which is copied
from the S-VOL to the T-VOL will be
copied from the T-VOL to the S-VOL.
When you perform the Fast Reverse Restore
without specifying the option of the
Incremental FlashCopy function, only the
copied part of data from the S-VOL to the
T-VOL will be copied before the Fast
Reverse Restore is executed.
