| 1. | A log chain starts with a full backup of the database
日志链以完整数据库备份开始。 |
| 2. | A continuous sequence of log backups is called a log chain
连续的日志序列称为“日志链” |
| 3. | Log chain a continuous sequence of transaction logs for a database
日志链中的点，恢复过程中前滚在该点停止。 |
| 4. | Discusses the most important log sequence numbers for creating a log chain
讨论了用于创建日志链的最重要的日志序列号。 |
| 5. | A reflexive relationship is used to compare rows within the same table . in queries , this is called a self - join . refresh data
在还原及紧接着的恢复之后，日志链产生分叉，从而创建一个新的恢复分支。 |
| 6. | If you switch from the full or bulk - logged recovery model to the simple recovery model , you break the backup log chain
如果从完整恢复模式或大容量日志恢复模式切换到简单恢复模式，则需要中断备份日志链。 |
| 7. | We recommend that you never use no log or truncate only to manually truncate the transaction log , because this breaks the log chain
尽管可用此选项手动截断事务日志，但是极力建议您不要这样做，因为这会将日志链断开。 |
| 8. | If a transaction log backup in this log chain is lost or damaged , you can restore only transaction logs before the missing transaction log
如果此事务日志链中的事务日志备份丢失或损坏，则您只能还原丢失的事务日志之前的事务日志。 |
| 9. | The database mirroring synchronous mode guarantees that the log chain is unaffected by a mirroring failover and that only valid log is restored
数据库镜像同步模式可以保证日志链不受镜像故障转移的影响，也可以保证只还原有效的日志。 |
| 10. | This alternative points out the redundant security offered by maintaining a chain of transaction log backups across a series of full database backups
此备选过程指出了冗余安全性，该安全性通过维护一系列完整数据库备份中的事务日志链备份来获得。 |
