FIELD: information technology.
SUBSTANCE: group of inventions relates to data storage and can be used for data replication. Method includes the steps of reading by the first data storage device a number of the current period of time at starting the current replication task; reading the second number, herewith the second number is a number corresponding to the last completed replication task associated with the current replication task; determination of the first number according to the number of the current period of time and the second number, herewith the first number is a number before the number of the current period of time at starting the current replication task, and the first number is a number following the second number; and replication of data to be replicated and address information of the data to be replicated, which are stored in the cache memory and correspond to the first number, to the second data storage device.
EFFECT: technical result is faster operation.
