【问题描述】*：在做备份和恢复测试过程中发现没法执行多个差备的恢复，以下是过程：

备份过程：

backup database backupset '/dm/bak/db_backup_base';
insert into test values(1112);
commit;

backup database increment backupset '/dm/bak/db_backup_increment_01';
insert into test values(2222);
commit;

backup database increment backupset '/dm/bak/db_backup_increment_02';
insert into test values(333);
commit;

backup archive log all backupset '/dm/bak/arch_log_backup_20230213';

rman恢复过程， 在恢复第2个差异备份的时候就报错了，感觉很奇怪
