For information about the effect of recovery models on backup and restore , see the following topics 接着数据库管理员还原并恢复尾日志备份( tail ) 。这将数据库恢复到故障点，从而恢复所有数据。
To restore the database to its state at 9 : 45 p . m . the point of failure , either of the following alternative procedures can be used 若要将数据库还原到晚上9 : 45 （故障点）时的状态，可以使用以下两种备选过程：
However , if there are no log backups , a database can be restored only to the end of the most recent backup of the data 这简化了备份和还原。但是，没有事务日志备份，便不可能恢复到故障点。只能还原到备份的结尾。
Route explorer appears to the network as just another router , though it forwards no traffic and is neither a bottleneck or failure point 对于网络来说就像另一台路由器，虽然它并不前转话务，也不是瓶颈或故障点。
However , if the database is damaged or lost when bulk logging is in effect , you cannot recover the database to the point of failure 不过，如果在大容量日志记录执行时数据库损坏或丢失，则无法将数据库恢复到故障点。
The full recovery model allows a database to be recovered to the point of failure , assuming that the tail of the log can be backed up after the failure 如果能够在出现故障后备份日志尾部，则可以使用完整恢复模式将数据库恢复到故障点。
Note that if the private network uses a single hub or network switch , that piece of equipment becomes a potential point of failure in your cluster 注意，如果该专用网络只使用一台集线器或网络交换机，此设备会成为群集内潜在的故障点。
As for safety , as all sdh equipment is formed in a ring , in which it is safe , the location vulnerable to faults is connection points of the coaxial cables 同时在安全性方面，由于sdh设备都成环，在sdh环内是安全的，故障点在于同轴电缆的连接点。
An application that accesses data has many potential points of failure that an attacker can exploit to retrieve , manipulate , or destroy sensitive data 访问数据的应用程序包含许多潜在的故障点，攻击者可以利用这些故障点来检索操纵或破坏敏感的数据。
In the network , the failure rate of equipment is high , and multiple network layers lead to added failure points , making them hard to be identified 设备故障率比较高。网络层次多导致故障点增加，故障点比较难判断，同时设备也不支持相应的检测故障功能。
