ABSTRACT:
A data storage system which copies data from source data storage volumes to target data storage volumes restricts a write operation to at least one source data storage volume (FREEZE), to prevent the updating of a source while the data of a consistency group of interdependent data is being copied. Program logic selects a source data storage volume to which the restriction applies as a verification volume; and the program logic responds to a verification request to first employ the verification volume to verify that the restriction remains in place with respect to the verification volume, and to allow a reset of the restriction (THAW).
