如果持续时间超过许可，以下备份的影响是什么？（选择所有适用的）
B、整体备份会失败，但任何成功备份的数据文件将能用于恢复。
The backup will fail after the duration period expires, but the datafiles that were backed up successfully will be able to be used in any restore operation. RMAN will prioritize any datafiles not backed up in subsequent backups. Also, the backup will not return an error when the duration expires and other commands will be executed.
在持续期间届满后备份将失败，但已成功备份的数据文件将可以被用在任何还原操作 。RMAN将 在随后的备份中优先考虑没有备份的数据文件。此外，当持续时间过期和其他命令将被执行时，备份将不会返回一个错误。来自 “ ITPUB博客 ” ，链接：https://blog.itpub.net/81227/viewspace-2126017/ ，如需转载，请注明出处，否则将追究法律责任。
