Systems and methods for replicating data from a production server to a backup server include identifying one or more data blocks of a file that were modified after a first time instant and before a second time instant. The file may be associated with a protected directory of the production server. An representative data block (e.g., including a hash value) for at least one of the identified data blocks may be computed using a cryptography algorithm, e.g., MD5 or SHA-1. The computed cryptographic data block representing the identified data block may then be sent for replication to the backup server. An operation performed between the first time instant and the second time instant on one or more files of the protected directory may be recorded, and sent to the backup server.
