Oracle 11g 备份与恢复 使用RMAN创建备份集举例

--%d: Specifies the name of the database

--%s: Specifies the backup set number. This number is a counter in the control file that is incremented for each backup set.

-- The counter value starts at 1 and is unique for the lifetime of the control file.

-- If you restore a backup control file, then duplicate values can result.

-- Also, CREATE CONTROLFILE initializes the counter back to 1

--%p: Specifies the piece number within the backup set.

-- This value starts at 1 for each backup set and is incremented by 1 as each backup piece is created.

RMAN> backup as backupset format '/backup01/df_%d_%s_%p.bus' tablespace users;
