示例

示例一：执行gs_restore，导入指定MPPDB_backup.dmp文件（自定义归档格式）中gaussdb数据库的数据和对象定义。

gs_restore -W password backup/MPPDB_backup.dmp -p 8000 -h 10.10.10.100 -d backupdbgs_restore[2017-07-21 19:16:26]: restore operation successfugs_restore: total time: 13053  ms

示例二：执行gs_restore，导入指定MPPDB_backup.tar文件（tar归档格式）中gaussdb数据库的数据和对象定义。

gs_restore backup/MPPDB_backup.tar -p 8000 -h 10.10.10.100 -d backupdb gs_restore[2017-07-21 19:21:32]: restore operation successfulgs_restore[2017-07-21 19:21:32]: total time: 21203  ms

示例三：执行gs_restore，导入指定MPPDB_backup目录文件（目录归档格式）中gaussdb数据库的数据和对象定义。

gs_restore backup/MPPDB_backup -p 8000 -h 10.10.10.100 -d backupdbgs_restore[2017-07-21 19:26:46]: restore operation successfulgs_restore[2017-07-21 19:26:46]: total time: 21003  ms

示例四：执行gs_restore，将gaussdb数据库的所有对象的定义导入至backupdb数据库。导入前，gaussdb存在完整的定义和数据，导入后，backupdb数据库只存在所有对象定义，表没有数据。

gs_restore -W password /home//backup/MPPDB_backup.tar -p 8000 -h 10.10.10.100 -d backupdb -s -e -c gs_restore[2017-07-21 19:46:27]: restore operation successfulgs_restore[2017-07-21 19:46:27]: total time: 32993  ms

示例五：执行gs_restore，导入MPPDB_backup.dmp文件中PUBLIC模式的所有定义和数据。在导入时会先删除已经存在的对象，如果原对象存在跨模式的依赖则需手工强制干预。

gs_restore backup/MPPDB_backup.dmp -p 8000 -h 10.10.10.100 -d backupdb -e -c -n PUBLICgs_restore: [archiver (db)] Error while PRO CES SING TOC:gs_restore: [archiver (db)] Error from TOC entry 313; 1259 337399 TABLE table1 gaussdbags_restore: [archiver (db)] could not execute query: ERROR:  cannot drop table table1 because other objects depend on itDETAIL:  view t1.v1 depends on table table1HINT:  Use DROP ... CASCADE to drop the dependent objects too.Command was: DROP TABLE public.table1;

手工删除依赖，导入完成后再重新创建。

gs_restore backup/MPPDB_backup.dmp -p 8000 -h 10.10.10.100 -d backupdb -e -c -n PUBLICgs_restore[2017-07-21 19:52:26]: restore operation successfulgs_restore[2017-07-21 19:52:26]: total time: 2203  ms

示例六：执行gs_restore，导入MPPDB_backup.dmp文件中PUBLIC模式下表hr.staffs的定义。在导入之前，hr.staffs表不存在。

gs_restore backup/MPPDB_backup.dmp -p 8000 -h 10.10.10.100 -d backupdb -e -c -s -n PUBLIC -t hr.staffsgs_restore[2017-07-21 19:56:29]: restore operation successfulgs_restore[2017-07-21 19:56:29]: total time: 21000  ms

示例七：执行gs_restore，导入MPPDB_backup.dmp文件中PUBLIC模式下表hr.staffs的数据。在导入之前，hr.staffs表不存在数据。

gs_restore backup/MPPDB_backup.dmp -p 8000 -h 10.10.10.100 -d backupdb -e -a -n PUBLIC -t hr.staffsgs_restore[2017-07-21 20:12:32]: restore operation successfulgs_restore[2017-07-21 20:12:32]: total time: 20203  ms

示例十二：执行gs_restore，将human_resource数据库导出文件进行解密并导入至backupdb数据库中。

示例十三：用户user1不具备将导出文件中数据导入至数据库backupdb的权限，而角色role1具备该权限，要实现将文件数据导入数据库backupdb，可以在导出命令中设置--role角色为role1，使用role1的权限，完成导出目的。
