Answer 2

值得一提的是，您可以还原备份-这样做有很多IF-但是如果您控制环境并且如果可以在关闭系统的同时关闭系统，则备份原始数据库可能很容易并将其还原到类似的环境中

我使用这种方法备份自己的开发环境

oracle@befb83f389c6:~$ sqlplus / as sysdba

oracle@befb83f389c6:~$ tar czvf spxe-20181017.tar.gz admin/ fast_recovery_area/ oradata/

要还原备份-您只需解压缩文件并替换现有文件夹

oracle@befb83f389c6:~$ rm -rdf admin/
oracle@befb83f389c6:~$ rm -rdf fast_recovery_area/
oracle@befb83f389c6:~$ rm -rdf oradata/
oracle@befb83f389c6:~$ tar xzvf spxe-20181017.tar.gz
