使用达梦数据库的disql工具给数据库做热备份_disql backup database

使用disql工具做热备份
热备份就是数据库实例的服务是开启的
[dmdba@localhost bin]$ ./DmServiceDMSERVER status
DmServiceDMSERVER (pid 5107) is running.
1.整库备份：
SQL> backup database full to “disql_quanbei” backupset ‘/dm8/dmbak/disql_quanbei’;
2.增量备份，基于一个备份集做增量备份
SQL> backup database increment base on backupset ‘/dm8/dmbak/disql_quanbei’ to “disql_zengliang” backupset ‘/dm8/dmbak/disql_zengliang’;
3.增量备份，基于最近一次备份集做增量备份
SQL> backup database increment to “disql_zengliang2” backupset ‘/dm8/dmbak/disql_zengliang2’;
