export ORACLE_BASE=D:apporacle
export ORACLE_HOME=D:apporacleproduct11.2.0dbhome_1
export ORACLE_SID=ecology
export PATH=$ORACLE_HOME/bin:$PATH
rman target / <<EOF
run{
allocate channel c1 type disk;
backup incremental level 0 tag "db0" format "D:akdb0_%d_%T_%s" database include current controlfile;
delete noprompt obsolete;
release channel c1;
}
增量备份 1级:差异增量
export ORACLE_BASE=D:apporacle
export ORACLE_HOME=D:apporacleproduct11.2.0dbhome_1
export ORACLE_SID=ecology
export PATH=$ORACLE_HOME/bin:$PATH
rman target / <<EOF
run{
allocate channel c1 type disk;
