Abstract

A method is used for bitmap-based synchronous replication in a data protection system. The method includes, upon re-establishing communication with a first storage node, requesting, by a second storage node, a first bitmap from the first storage node. The method includes determining, by the second storage node, a set of data blocks to change on the first storage node based on the first bitmap and a second bitmap on the second storage node. The method also includes sending, by the second storage node to the first storage node, the set of data blocks.
