A method to copy computer files, where that method includes receiving a computer file, mapping that file to its constituent blocks, generating meta-data describing those constituent blocks, saving that meta-data in a memory device, and copying the file to one or more information storage media, where the mapping step, the generating step, and the saving step, are performed substantially synchronously, and where the copying step is performed at a later time. A data storage and retrieval system comprising a computer useable medium having computer readable program code disposed therein to copy computer files on one or more information storage media disposed therein. A computer program product usable with a programmable computer processor having computer readable program code embodied therein for copying computer files. |
