在RMAN的备份中，可以经由过程Exclude呼吁解除某些不需要备份的表空间。
1 j" F8 D. ?8 Q9 W* n 这样可以缩减备份的容量，对备份进行恰当优化和调整。( m' @3 H9 A# G) J/ D K+ T
解除某个表空间可以使用近似如下呼吁：
V' }' C( i: w5 X1 a9 S$ g. q configure exclude for tablespace users;# H8 R! K: r! u! ~- _, M
其设置可以在RMAN中经由过程show exclude呼吁来查看。
! U" \& U$ v* t; o5 s 如不美观未来想姑且增添解除表空间的备份，站提醒: 可以经由过程以下呼吁实现：
& U( Q0 I5 m) m' [0 v backup database noexclude;
: K! B' B9 m; \+ p 如不美观想打消解除设置则可以使用如下呼吁：
& c4 f# p4 L& X; a( J0 z CONFIGURE EXCLUDE FOR TABLESPACE users CLEAR;
" T' F4 H2 C. {: y6 `4 ^ 此外常用的解除备份呼吁还有：
