  • Method for performing replication control in storage system with aid of relationship tree within database, and associated apparatus
    Patent number: 10379777
    Abstract: A method for performing replication control in a storage system and an associated apparatus are provided. The method may include: recording relationships between a protection target in a first storage server and a plurality of snapshots of the protection target in a database of the first storage server and updating the database during recording the relationships; selecting a non-replicated snapshot that has not been replicated from the first storage server to a second storage server; selecting a replicated snapshot that has been replicated from the first storage server to the second storage server as reference of replication difference calculation according to a relationship tree within the database; generating snapshot difference data between the non-replicated snapshot and the replicated snapshot; and transmitting the snapshot difference data from the first storage server to the second storage server, to replicate the non-replicated snapshot from the first storage server to the second storage server.
