openGauss物理备份恢复之gs_basebackup

gs_basebackup背景说明

• gs_basebackup仅支持全量备份，不支持增量。
• gs_basebackup当前支持热备份模式和压缩格式备份模式。
• gs_basebackup在备份包含绝对路径的表空间时，如果在同一台机器上进行备份，可以通过tablespace-mapping重定向表空间路径，或使用归档模式进行备份。

gs_basebackup参数说明

gs_basebackup参数可以分为如下几类：

• -D directory 备份文件输出的目录，必选项。

常用参数：

• -c，–checkpoint=fast|spread 设置检查点模式为fast或者spread(默认)。

• -l，–label=LABEL 为备份设置标签。

• -P，–progress 启用进展报告。

• -v， –verbose 启用冗长模式。

• -V， –version 打印版本后退出。

• -?，–help 显示gs_basebackup命令行参数。

• -T，–tablespace-mapping=olddir=newdir

  在备份期间将目录olddir中的表空间重定位到newdir中。为使之有效，olddir必须正好匹配表空间所在的路径（但如果备份中没有包含olddir中的表空间也不是错误）。olddir和newdir必须是绝对路径。如果一个路径凑巧包含了一个=符号，可用反斜线对它转义。对于多个表空间可以多次使用这个选项。

• -F，–format=plain|tar

  设置输出格式为plain(默认)或者tar。没有设置该参数的情况下，默认–format=plain。plain格式把输出写成平面文件，使用和当前数据目录和表空间相同的布局。当集簇没有额外表空间时，整个数据库将被放在目标目录中。如果集簇包含额外的表空间，主数据目录将被放置在目标目录中，但是所有其他表空间将被放在它们位于服务器上的相同的绝对路径中。tar模式将输出写成目标目录中的 tar 文件。主数据目录将被写入到一个名为base.tar的文件中，并且其他表空间将被以其 OID 命名。生成的tar包，需要用gs_tar命令解压。

• -X， –xlog-method=fetch|stream

  设置xlog传输方式。没有设置该参数的情况下，默认–xlog-method=stream。在备份中包括所需的预写式日志文件（WAL文件）。这包括所有在备份期间产生的预写式日志。fetch方式在备份末尾收集预写式日志文件。因此，有必要把wal_keep_segments参数设置得足够高，这样在备份末尾之前日志不会被移除。如果在要传输日志时它已经被轮转，备份将失败并且是不可用的。stream方式在备份被创建时流传送预写式日志。这将开启一个到服务器的第二连接并且在运行备份时并行开始流传输预写式日志。因此，它将使用最多两个由max_wal_senders参数配置的连接。只要客户端能保持接收预写式日志，使用这种模式不需要在主控机上保存额外的预写式日志。

• -x，–xlog 使用这个选项等效于和方法fetch一起使用-X。

• -Z –compress=level

  启用对 tar 文件输出的 gzip 压缩，并且制定压缩级别（0 到 9，0 是不压缩，9 是最佳压缩）。只有使用 tar 格式时压缩才可用，并且会在所有tar文件名后面自动加上后缀.gz。

• -z 启用对 tar 文件输出的 gzip 压缩，使用默认的压缩级别。只有使用 tar 格式时压缩才可用，并且会在所有tar文件名后面自动加上后缀.gz。

• -t，–rw-timeout 设置备份期间checkpoint的时间限制，默认限制时间为120s。当数据库全量checkpoint耗时较长时，可以适当增大rw-timeout限制时间。

连接参数

• -h, –host=HOSTNAME 指定正在运行服务器的主机名或者Unix域套接字的路径。
• -p，–port=PORT 指定数据库服务器的端口号
• -U，–username=USERNAME 指定连接数据库的用户。
• -s, –status-interval=INTERVAL 发送到服务器的状态包的时间(以秒为单位)
• -w,–no-password 不出现输入密码提示。
• -W, –password 当使用-U参数连接本地数据库或者连接远端数据库时，可通过指定该选项出现输入密码提示。
