Abstract
A system and method for real time data migration in a networked computer system uses a known operating system feature, a sparse file, to represent a migrated file. The sparse file consumes a minimum amount of physical space on the file server but is defined as having the same size and attributes as the original final. When a user accesses a migrated file, the file appears to be resident on the file server and is automatically and transparently returned to the file server from an optimized storage location in a hierarchical storage management system.
