如果您选择使用归档日志记录，并执行联机备份和前滚恢复，那么您可以恢复到数据丢失最少的那个时间点，或者恢复到结束日志的时候。
If you choose to have archive logging, and do an online backup and roll forward recovery, you can recover to a point in time or to the end of the logs for the minimum loss of data.
例如，如果您已使用日期对访问日志归档，则可以选择在某个特定日期范围内的所有文件。
For example, if you have filed your access logs using dates, you can then select all of the files within a specific range of dates.
在显示的Archive name and parameters窗口中，选择ZIP作为归档文件格式。
In the archive name and parameters window that displays, select ZIP as the archive format.
