Abstract
Techniques for replicating data involve: acquiring a first snapshot of a data block set, the first snapshot being a snapshot before a first subset of the data block set starts to be replicated; acquiring a second snapshot of the data block set, the second snapshot being a snapshot of the data block set when replication of the first subset is completed; and determining, based on a difference between the second snapshot and the first snapshot, a second subset of the data block set, the second subset being different from the first subset. Accordingly, such techniques can improve data protection efficiency in asynchronous replication.
