Backward recovery requires no database preparation. The backward recovery process alters the database by reversing maintenance transactions, returning it to its unchanged state.
RECOVERY OPTION=BACKWARD performs by reading the selected data forward using the name RXX and sorting it into reverse sequence.
You can use the STIME= and ETIME= keywords to reverse part of a job, but this is not a recommended technique. Examine any backward recovery, other than an entire job, carefully.
