Method and apparatus for creating reliably duplicatable tape volumes without copying any padding

摘要: Method and apparatus for creating reliably duplicatable tape volumes by padding the volume label on source with compression resistant random data, copying such a to that does not have padding. In preferred embodiment, application program uses present invention create volume. The amount of be inserted can specified either as fixed amount, or dynamically variable parameter changed basis statistically significant results sampling. When padded is then duplicated another tape, without padding, likelihood data will "fit" unpadded destination becomes much more predictable.
