RECOVER
Thực hiện phục hồi dữ liệu từ bản RMAN backups hoặc bản copies. Apply những redo entry trong redo log files/archived redo log và incremental backups tới các datafiles hoặc data blocks được khôi phục từ bản backup hay bản datafile copy, để cập nhật với thời gian xác định.

RMAN> RESTORE DATAFILE 64;

Các bước thực hiện recovery:
1. Mount hay open Oracle database. Mount database khi thực hiện phục hồi toàn bộ database, hay open database khi thực hiện online tablespace/datafile recovery.
2. Thực hiện phục hồi không đầy đủ (incomplete recovery), sử dụng lệnh SET UNTIL để xác định thời gian, SCN, hay log sequence number mà quá trình phục hồi kết thúc. Có thể thay bằng mệnh đề UNTIL trong lệnh RESTORE và RECOVER.
3. Khôi phục những datafile cần thiết với lệnh RESTORE
4. Phục hồi các datafile với lệnh RECOVER
5. Đặt database trong chế độ hoạt động bình thường. Ví dụ, open hay đặt tablespaces/datafiles vào chế độ online.
