您要查找的是不是：
- A log chain starts with a full backup of the database. 日志链以完整数据库备份开始。
- To restore a database up to the point of failure, the log chain must be intact. 若要将数据库还原到故障点,必须保证日志链是完整的。
- The tail-log backup prevents work loss and keeps the log chain intact. 尾日志备份可以防止工作丢失并确保日志链的完整性。
- An uninterrupted sequence of log backups contains the complete log chain of the database, which is said to be unbroken. 不间断的日志备份序列包含数据库的完整(即连续不断的)日志链。
- Forcing log truncation breaks the log chain and leaves your database vulnerable until the next full database backup. 强行截断日志会破坏日志链,并在下次完整备份数据库之前使数据库处于容易受到攻击的状态。
- 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。
- However, a database administrator can break the log chain by changing the recovery model to simple and back to full or bulk-logged. 但是,如果数据库管理员先将恢复模式更改为简单恢复模式,然后再将其更改回完整或大容量日志恢复模式,会使日志链断开。
- You cannot roll forward across recovery model changes that involve the simple recovery model, because the log chain is broken. 由于日志链已断开,因此无法在涉及简单恢复模式的恢复模式切换中前滚。
- Under the full recovery model, and sometimes under the bulk-logged recovery model, an unbroken log chain lets you to restore the database to any point in time. 在完整恢复模式下(或者在大容量日志恢复模式下的某些时候),连续不断的日志链让您可以将数据库还原到任意时间点。
- Immediately after you complete the switch to the full recovery model or bulk-logged recovery model, take a full or differential database backup to start the log chain. 从简单恢复模式切换到完整模式之后,建议您:立即执行完整数据库备份或差异数据库备份。
- A log chain begins with the first log backup taken after the database is created or when it is switched from the simple to the full or bulk-logged recovery model. 日志链的开始处是创建数据库后所做的第一个日志备份,或者是数据库从简单模式切换到完整模式或大容量日志恢复模式时所做的第一个日志备份。
- A new log chain starts either with the first full database backup following database creation or after switching from the simple recovery model to the full or bulk-logged recovery model. 新的日志链将随数据库创建后的第一个完整数据库备份而启动,或在从简单恢复模式切换到完整或大容量日志恢复模式后启动。

- Do you know how to log in to the system? 你知道怎么登录进入这个系统吗？
- I reached for a floating log with my foot. 我伸脚去钩取一段漂浮着的木头。
- They are sawing a log into planks. 他们把原木锯成一块块厚板。
- The chain has fallen foul of plants in the water. 链条已和水中的植物缠绕在了一起。
- She has a gold chain about her neck. 她在脖子的周围挂着一根金项链。
