Abstract: A computer-implemented method is provided for generating a sequence of commands for replicating data on a source storage system to a destination storage system. The source and destination storage system support a first and a second remote file access protocol. The method involves i) scanning a directory of the source storage system for file system objects by the first and second remote file access protocol thereby obtaining a respective first and second representation of the file system objects; and ii) generating the sequence of commands based on the first and second representation and based on a predetermined rule set comprising rules for generating a command for replicating a file system object depending on a difference in representation of file system objects by the first and second remote file access protocol.

Abstract: A method for migrating data from a source storage system to a destination storage system comprises the following steps. In a first step, an initial copy is performed. In a second step, one or more incremental copies are performed and then a final cutover incremental copy is performed. The performing the one or more incremental copies further comprises excluding from a respective one of the one or more incremental copies first data portions of the data that are likely to change before this performing a final cutover incremental copy.

Abstract: A system for serving information includes a router; archive storage medium units connected to the router for storing information data; delivere storage medium units connected to the router for partially storing information data from the archive storage medium units; end devices each having an input and a display connected to the router for outputting demand data requesting selected information data; and a controller connected to the router for managing distribution of the information data.
