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.

Abstract: A system and method is provided for measurements of building facade elements by combining ground-level and orthogonal imagery. The measurements of the dimension of building facade elements are based on ground-level imagery that is scaled and geo-referenced using orthogonal imagery. The method continues by creating a tabular dataset of measurements for one or more architectural elements such as siding (e.g., aluminum, vinyl, wood, brick and/or paint), windows or doors. The tabular dataset can be part of an estimate report.
