Windows下实现PostgreSQL自动备份_MySQL
bitsCN.com
本文介绍怎样创建一个Windows批处理文件来自动备份PostgreSQL数据库。 背景 在我工作上一个使用PostgreSQL数据库的项目上需要一个自动化系统来每天执行备份。经过一番研究决定通过创建一个Windows批处理文件并添加到Windows计划任务中来实现。 下面是具体步骤: 怎样配置 第一步: 下载批处理文件。 第二步: 你可以通过一个简单的命令(schtasks /?查看帮助)或者使用图形界面(开始-控制面板-系统和安全-管理工具-任务计划程序)运行任务计划管理工具,还可以在%SYSTEMROOT%/System32目录下双击Taskschd.msc来启动它。 第三步: 你可以通过向导或通过XML文件导入信息来创建基本任务。向导方式创建方法见任务计划程序帮助,下面介绍下命令行语法: 1 schtasks /Create [/S

如果在Windows防火墙中远程任务计划管理被禁用而文件和打印共享被启用并且远程注册表服务正在运行,远程计算机上将会被创建一个V1任务即使没有使用参数V1。参数V1表明一个任务对下层系统可见。 使用代码 脚本: 01 @ECHO OFF 02 @setlocal enableextensions@cd /d "%~dp0" 03 04 SET PGPATH=C:/"Program Files"/PostgreSQL/9.1/bin/ 05 SET SVPATH=f:/ 06 SET PRJDB=demo 07 SET DBUSR=postgres 08 FOR /F "TOKENS=1,2,3 DELIMS=/ " %%i IN ('DATE /T') DO SET d=%%i-%%j-%%k 09 FOR /F "TOKENS=1,2,3 DELIMS=: " %%i IN ('TIME /T') DO SET t=%%i%%j%%k 10 11 SET DBDUMP=%PRJDB%_%d%_%t%.sql@ECHO OFF 12 %PGPATH%pg_dump -h localhost -p 5432 -U postgres %PRJDB% > %SVPATH%%DBDUMP% 13 14 echo Backup Taken Complete %SVPATH%%DBDUMP%
初始值
- PGPATH - PostgreSQL路径
- SVPATH - 备份文件路径
- PRJDB - 要备份的数据库名
- DBUSR - 数据库用户名

Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

Mastering Debian system log monitoring is the key to efficient operation and maintenance. It can help you understand the system's operating conditions in a timely manner, quickly locate faults, and optimize system performance. This article will introduce several commonly used monitoring methods and tools. Monitoring system resources with the sysstat toolkit The sysstat toolkit provides a series of powerful command line tools for collecting, analyzing and reporting various system resource metrics, including CPU load, memory usage, disk I/O, network throughput, etc. The main tools include: sar: a comprehensive system resource statistics tool, covering CPU, memory, disk, network, etc. iostat: disk and CPU statistics. mpstat: Statistics of multi-core CPUs. pidsta
