Abstract
Needless migration of duplicate file data is avoided by recording in a database a record of migration of a first instance of a replicated file from a source file server to a target file server. When migrating a subsequent instance of a replicated file to the target file server, the database is searched for a record of replication of a first instance of the replicated file to the target file server. If such a record is found, the subsequent instance is replicated by sending from the source file server to the target file server attributes of the subsequent instance of the replicated file and an identification of the previously migrated data of the replicated file without re-transmission of the previously migrated data of the replicated file.
