Automatic PostgreSQL backup tutorial in Windows and postgresql backup tutorial

Background
An automated system is required for my work on a PostgreSQL database project to perform backups every day. After some research, we decided to create a Windows batch processing file and add it to the Windows scheduled task.
The procedure is as follows:

How to configure
Step 1:
Download the batch file.

Step 2:
You can use a simple command (schtasks /? View help) or use a graphical interface (START-control panel-system and security-management tools-Task Scheduler) to run the task scheduler management tool, you can also double-click Taskschd in the % SYSTEMROOT % \ System32 directory. msc to start it.
 
Step 3:
You can use the wizard or XML file import information to create a basic task. For how to create a wizard, see the task scheduler help. The following describes the command line Syntax:
 

schtasks /Create [/S <system> [/U <username> [/P [<password>]]]]  [/RU <username> [/RP <password>]] /SC <schedule> [/MO <modifier>] [/D <day>]  [/M <months>] [/I <idletime>] /TN <taskname> /TR <taskrun> [/ST <starttime>]  [/RI <interval>] [ {/ET <endtime> | /DU <duration>} [/K] [/XML <xmlfile>] [/V1]]  [/SD <startdate>] [/ED <enddate>] [/IT] [/Z] [/F] 

View the help of this command:
 

schtasks /Create /?

 

If remote task scheduler management is disabled in Windows Firewall, file and print sharing are enabled, and the remote registry service is running, a V1 task is created on the remote computer even if the parameter V1 is not used. The V1 parameter indicates that a task is visible to the lower-level system.
