Abstract

See full text

According to one embodiment, a method for determining a transfer order of files includes acquiring the access count of a replicated file at a production site and at a remote site, these access counts being reflected in the order for asynchronous replication. In addition, the access count of backed up files at the remote site is also acquired and reflected in the order for asynchronous replication according to another embodiment. This allows for improved determination of the transmission order of files (according to priority based on usage) from a production site to a remote site in an asynchronous replication function.
