說明：
1、只要有備份與歸檔存在，RMAN也可以實現資料庫的完全恢復（不丟失資料）
2、同OS備份資料庫恢復，適合於丟失大量資料檔案，或包含系統資料檔案在內的資料庫的恢復
3、目標資料庫在mount下進行，如果恢復成功，再開啟資料庫。
4、RMAN的備份與恢復命令相對比較簡單並可靠，建議有條件的話，都採用RMAN進行資料庫的備份。
參考itpub上piner的備份與恢復案例：

說明：
1、只要有備份與歸檔存在，RMAN也可以實現資料庫的完全恢復（不丟失資料）
2、同OS備份資料庫恢復，適合於丟失大量資料檔案，或包含系統資料檔案在內的資料庫的恢復
3、目標資料庫在mount下進行，如果恢復成功，再開啟資料庫。
4、RMAN的備份與恢復命令相對比較簡單並可靠，建議有條件的話，都採用RMAN進行資料庫的備份。
