If using online backup, recognize that the backup image will be useless without the logs of all transactions that occurred while DB2 was backing up the database.
如果使用在线备份，要知道除非具有在DB 2备份数据库时发生的所有事务的日志，否则备份映像没有任何作用。
When performing an offline database backup, the catalog partition needs to be backed separately; however, this is not a concern with online backups, as the logs are included in the backup image.
当执行离线数据库备份时，需要单独备份编目分区。但是，在线备份时就不需要这样，因为日志是包括在备份镜像中的。
Instead, the changes between each backup image are captured in the DB2 logs.
相反，每个备份映像之间的更改被DB 2日志捕获。
These two pieces (the backup image and the logs representing all work since the backup) are the fundamental building blocks of a DB2 disaster recovery plan.
这两个部分(备份映像和反映备份之后的所有更改的日志)是DB 2灾难恢复计划的基础构建块。
If you needed to restore on Monday, you would restore with the Sunday night backup image, and apply all available logs.
如果您需要恢复到Monday，则需要使用Sunday夜间备份映像进行恢复，并应用所有可用的日志。
Figure 3 shows how recovery requires a full backup image, the last incremental backup, all delta backups since the last incremental backup, and the logs.
图3显示了恢复如何使用完整的备份映像、最后的增量备份、上一次增量备份之后的所有增量备份和日志。
You should include the logs in the backup image, which is the default behavior as of DB2 Version 8.2 and 9.5.
应该将日志包括在备份镜像中，从DB 2Version 8.2到9.5，这是默认行为。
Starting with DB2 Express-C Version 8.2, you can include logs into your backup image with the include logs option in the backup command.
从DB2Express-CVersion 8.2 开始，可以在备份命令中使用includelogs选项，从而将日志包含在备份映像中。
I quickly wrote a PHP script that extracts the Session Start and Sessions Close markers and timestamps from these logs and transfers them into an image.
我迅速地写了一个基于PHP的东西，摘录了“SessionStart”和“SessionClose”（会议开始/结束）的标记和那些日志的时间印记，然后把它们全转成一张图。
Using the data of outcrops, cores, thin sections and image logs, we analyzed the fracture origin types, distribution characteristics and formation sequences.
利用地表露头、岩心、薄片和成像测井等资料，对该区裂缝的成因类型、分布特征及其形成序列进行了分析。
ALD image logs reveal borehole shape features such as hole spiraling and stress-induced breakout.
ALD成像测井可以揭示井眼形状特征，例如井眼螺旋以及应力诱导裂缝。
ALD provides downhole density measurements, including high-quality borehole image logs, to help optimize wellbore placement through geosteering and to reduce geological uncertainties.
ALD可以进行井下密度测量，包括高质量的井眼成像测井，利用地质导向帮助作业者优化井位，减少地质不确定性。
