RECLAIMING OF SEQUENTIAL STORAGE MEDIUM |
| 摘要 |
Software for reclaiming a sequential storage medium that includes: copying all active data blocks in a first part of sequentially written data on a first sequential storage medium, to a second sequential storage medium, the first part extending from a first intermediate position to an end of the sequentially written data; and defining all data blocks in a second part of the sequentially written data on the first sequential storage medium, to be a new sequentially written data, the second part extending from a beginning to a second intermediate position of the sequentially written data, and excluding the active data blocks copied to the second sequential storage medium. |

1. A computer-implemented method for reclaiming a sequential storage medium, the method comprising:
copying all active data blocks in a first part of sequentially written data on a first sequential storage medium, to a second sequential storage medium, the first part extending from a first intermediate position to an end of the sequentially written data; and defining all data blocks in a second part of the sequentially written data on the first sequential storage medium, to be a new sequentially written data, the second part extending from a beginning to a second intermediate position of the sequentially written data, and excluding the active data blocks copied to the second sequential storage medium. |
