说明：
本篇所提到的异机是指从一个集群的备份，恢复其中一个租户到另一个集群中。也就是说，两个OB集群挂载相同的nfs，两个集群都做备份后，将其中一个集群备份中的某个租户，恢复到另一个集群中。
经过实际测试，执行命令恢复时没报错，也没有任何恢复任务，但查看rs事件，提示恢复event是restore_failed失败的。。查看历史恢复表__all_restore_history，info信息提示不支持 ROOTSERVICE : OB_NOT_SUPPORTED(-4007)。
毕竟本人也是初学，可能方法不对，还是不支持，暂且先不管结果如何，这类需求应该还算是实际正常的需求，本文先记录于此，后续继续跟踪寻求解决方法。
参考上一篇备份恢复黑屏命令行实操：OceanBase 2.2集群实战第十篇——OceanBase的备份与恢复
之所以命令行操作备份恢复，对于dba们来说，与ocp流程化的操作相比，还是切实的键盘操作体验更要踏实亲切些。。。不知道广大dba朋友们有没有这种感觉。。。(>_<)
本系列总的专栏：一步一步学习OceanBase系列
(补充)问题解决：
异机恢复问题解决！
测试发现从测试区的物理备份，恢复到生产区，验证是成功的。。而生产区的物理备份无法恢复到测试区。
最终分析找到问题原因是因为生产区和测试区两个OB集群的LDC不一致导致。
生产区环境是同城三中心部署，测试区环境当时测试LDC时，修改成了两地三中心部署模式，导致生产区的备份恢复到测试区时就不支持，而测试区的备份可以恢复到生产区。
本篇实操之前，先对上一篇备份恢复作一下补充。
1、关于备份清理策略
• auto_delete_expired_backup 参数控制是否自动清理备份文件，默认为False不自动清理。
• backup_recovery_window 参数控制备份文件保留周期(以天为单位)，默认为0。
如：
alter system set auto_delete_expired_backup=true;
alter system set backup_recovery_window=7;
2、关于 log archivelog status 日志归档状态问题
经过我几次测试发现，开启日志archivelog归档后，并且执行了一次合并，合并也是完成后，在执行备份的时候，还是会遇到报错，日志归档状态是INTERRUPTED或者BEGINNING
obclient> alter system backup database;
ERROR 9040 (HY000): backup can not start, because log archive is not doing. log archive status : INTERRUPTED.
obclient>
obclient> alter system backup database;
ERROR 9040 (HY000): backup can not start, because log archive is not doing. log archive status : BEGINNING.
obclient>
就想知道怎么查看当前日志归档状态信息？
关于日志归档状态，主要是查看内部表cdb_ob_backup_archivelog_summary中的status，当状态变成DOING时，才能进行后续的备份操作。
obclient> select * from cdb_ob_backup_archivelog_summary;

log_archive_status 日志归档状态的种类，主要有：
• STOP: 没有日志归档备份
• BEGINNING: 正在启动日志归档备份
• DOING: 正在日志归档备份
• STOPPING: 停止日志归档备份
• INTERRUPTED: 日志归档备份断流了
关于log_archive_status状态中，BEGINGING 一般是正常的，持续时间和租户数量有关，一般单租户 60s，两个租户 120s。
关于 INTERRUPTED状态：可以查rs事件信息，从内部表__all_rootservice_event_history可以看到哪个rs设置的INTERRUPTED，需要到对应的server上看rs的日志。
obclient> select * from __all_rootservice_event_history where module like '%archive%' order by gmt_create desc limit 30;

另外，如果当日志归档开启后，没有执行过合并，执行备份时也会报错，因为日志开启时间大于上一次合并冻结时间，需要执行一次合并。
obclient> alter system backup database;
ERROR 9040 (HY000): backup can not start, because log archive start timestamp is bigger than frozen timestamp, need major freeze first. start timestamp : 1612147273821930, frozen timestamp : 1612116010844801 .

1异机恢复问题解决！测试发现从测试区的备份，恢复到生产区，验证是成功的。。最终找到问题原因LDC不一致导致。生产区是同城三中心部署，测试区当时测试LDC时，修改成了两地三中心部署模式，生产区的备份恢复到测试区时就不支持，而测试区的备份可以恢复到生产区。
