| 1. | Therefore , a copy - only backup cannot serve as a differential base
因此，仅复制备份不能用作差异基准。 |
| 2. | Differential backups are taken in relation to a specific differential base
差异备份根据特定的“差异基准 |
| 3. | Generally , the older a base is , the larger a new differential backup will be
通常，差异基准越旧，新的差异备份就越大。 |
| 4. | For each extent updated since the base , the bit is set to 1 in the bitmap
对于自建立差异基准后更新的每个区，该位在位图中设置为1 。 |
| 5. | The following illustration shows the easiest backup strategy under the full recovery model
在还原差异备份之前，必须先还原其差异基准。 |
| 6. | A differential base is a data backup is the reference point for the differential backup
差异基准是一个数据备份，它是差异备份的参考点。 |
| 7. | Base of the differential . a differential backup includes only the data that has changed since the
差异备份仅包括自建立差异基准后更改的数据。 |
| 8. | A differential backup includes only the extents that changed since the differential base was created
差异备份仅包括自创建差异基准之后更改的区。 |
| 9. | Usually , taking a backup changes the database and affects how later backups are restored
例如，常规数据备份可以用作一个或多个后续差异备份的差异基准。 |
| 10. | When a read - only database is detached and then reattached , the differential base information is lost
分离再重新附加只读数据库后，会丢失差异基准信息。 |
