Rman can perform db,tablespace,datafile,block level and TSPITR recovery in previous versions of 12C, 12C introduces table-level recovery
A single table can be recovered without opening the flashback.
example, create a table
Sql> alter session set CONTAINER=PDB2;
Session altered.
Sql> CREATE TABLE Frank.t1 as SELECT * from Dba_tables;
Table created.
Backing Up the database
rman> backup Database;

It also creates a new auxiliary instance, then does a full-library restore on auxiliary instance and then exports and imports through the DataPump tool
The whole process is very similar to the TSPITR.

Note the name of the common User reference table is "C # #frank". T1, instead of "C # #frank. T1", the following error is reported
