【问题描述】*：DM管理工具备份表空间后，删除属于该表空间的表table_1内部分数据，备份前6条数据，删除后3条数据，然后执行表空间备份还原后，表table_1还是3条数据，并没有恢复到备份的时候，怎么回事呀？
下面是执行的的操作命令：
RMAN> restore database '/u01/dm8/dmdata/DMDB/dm.ini' tablespace "systesttbs" from backupset '/u01/dm8/dmdata/DMDB/bak/TS_systesttbs_FULL_2023_04_14_14_49_54';
restore database '/u01/dm8/dmdata/DMDB/dm.ini' tablespace "systesttbs" from backupset '/u01/dm8/dmdata/DMDB/bak/TS_systesttbs_FULL_2023_04_14_14_49_54';
