 A few days ago I had to create a backup script for my PostgreSQL server running on Windows. After few minutes the script looks like this: @echo off SET DBHOST=localhost set DBNAME=YOUR_DB_NAME set DBUSER=YOUR_DB_USERNAME set PGPASSWORD=YOUR_DB_PASSWORD :: Path to PostgreSQL pg_dump.exe set PGDUMP="C:\Program Files\PostgreSQL\14\bin\pg_dump.exe" :: Get date in YYYY-MM-DD format set CURRENTDATE=%date:~6,4%%date:~3,2%%date:~0,2% set BACKUPDIR=BACKUP_DIRECTORY %PGDUMP% --host %DBHOST% --port 5432 --format custom --blobs --username %DBUSER% -f "%BACKUPDIR%\%CURRENTDATE%-%DBNAME%.backup" %DBNAME%   And it is working now like a charm :)
