gs_dumpall

背景信息
- gs_dumpall是openGauss用于导出所有数据库相关信息工具，它可以导出openGauss数据库的所有数据，包括默认数据库postgres的数据、自定义数据库的数据、以及openGauss所有数据库公共的全局对象。
- gs_dumpall工具由操作系统用户omm执行。
- gs_dumpall工具在进行数据导出时，其他用户可以访问openGauss数据库（读或写）。
- gs_dumpall工具支持导出完整一致的数据。例如，T1时刻启动gs_dumpall导出openGauss数据库，那么导出数据结果将会是T1时刻该openGauss数据库的数据状态，T1时刻之后对openGauss的修改不会被导出。
- gs_dumpall在导出openGauss所有数据库时分为两部分：
- gs_dumpall自身对所有数据库公共的全局对象进行导出，包括有关数据库用户和组，表空间以及属性（例如，适用于数据库整体的访问权限）信息。
- gs_dumpall通过调用gs_dump来完成openGauss中各数据库的SQL脚本文件导出，该脚本文件包含将数据库恢复为其保存时的状态所需要的全部SQL语句。
以上两部分导出的结果为纯文本格式的SQL脚本文件，使用gsql运行该脚本文件可以恢复openGauss数据库。

gs_dump

背景信息
- gs_dump是openGauss用于导出数据库相关信息的工具，用户可以自定义导出一个数据库或其中的对象（模式、表、视图等）。支持导出的数据库可以是默认数据库postgres，也可以是自定义数据库。
- gs_dump工具由操作系统用户omm执行。
- gs_dump工具在进行数据导出时，其他用户可以访问openGauss数据库（读或写）。
- gs_dump工具支持导出完整一致的数据。例如，T1时刻启动gs_dump导出A数据库，那么导出数据结果将会是T1时刻A数据库的数据状态，T1时刻之后对A数据库的修改不会被导出。
- gs_dump支持将数据库信息导出至纯文本格式的SQL脚本文件或其他归档文件中。
- 纯文本格式的SQL脚本文件：包含将数据库恢复为其保存时的状态所需的SQL语句。通过gsql运行该SQL脚本文件，可以恢复数据库。即使在其他主机和其他数据库产品上，只要对SQL脚本文件稍作修改，也可以用来重建数据库。
- 归档格式文件：包含将数据库恢复为其保存时的状态所需的数据，可以是tar格式、目录归档格式或自定义归档格式。该导出结果必须与gs_restore配合使用来恢复数据库，gs_restore工具在导入时，系统允许用户选择需要导入的内容，甚至可以在导入之前对等待导入的内容进行排序。

实验过程

二进制备份chnbs数据库

gs_dump -p 15400 chnbs -F c -f home/omm/chnbs.binary

sql文本导出chnbs数据库

gs_dump -p 15400 chnbs -f home/omm/chnbs.sql

tar包备份chnbs数据库

gs_dump -p 15400 chnbs -F t -f home/omm/chnbs.tar

文件夹备份chnbs数据库

gs_dump -p 15400 chnbs -F d -f home/omm/chnbs

sql文本导出chnbs数据库下名为salene的schema

gs_dump -p 15400 chnbs -n salene -f home/omm/chnbs_salene.sql

二进制备份chnbs数据库下名为salene的schema

gs_dump -p 15400 chnbs -n salene -F c -f home/omm/chnbs_salene.binary

综合备份出的文件，二进制备份压缩比最高，实验过程中最高达到1:13，tar包备份和sql文本备份无压缩。

gs_restore

背景信息

gs_restore是openGauss提供的针对gs_dump导出数据的导入工具。通过此工具可将由gs_dump生成的导出文件进行导入。

gs_restore工具由操作系统用户omm执行。

主要功能包含：
- 导入到数据库
  
  如果连接参数中指定了数据库，则数据将被导入到指定的数据库中。其中，并行导入必须指定连接的密码。
- 导入到脚本文件
  
  如果未指定导入数据库，则创建包含重建数据库所必须的SQL语句脚本并写入到文件或者标准输出。等效于直接使用gs_dump导出为纯文本格式。
