I have a problem with executing a bat file – if I run this ascript manually, then the backup works – if I run the bat file via a task, then a file is created, but it is empty

SETLOCAL

rem ----EINSTELLUNGEN--------------------------------

set "MySQLPath=C:xampp1mysqlbin"
rem set "BackupPath=Z:Sicherung_Datenbank"
set "BackupPath=\192.168.178.98Sicherung_Datenbank"
set "MySQLDB=2023"
set "MySQLUser=admin"
set "MySQLPwd=admin"
set "MySQLPort=3306"

rem -------------------------------------------------


set "BackupDate=%date:~-4%%date:~-7,2%%date:~-10,2%"
set "BackupTime=%time:~-11,2%%time:~-8,2%%time:~-5,2%"

set "BackupFile=%BackupDate%_%BackupTime%.sql"

%MySQLPath:~0,2%

cd %MySQLPath%bin

echo DS Datenbank-Backup wird erstellt... [Datenbank: %MySQLDB%]

mysqldump -u%MySQLUser% -p%MySQLPwd% %MySQLDB% --port=%MySQLPort%> "%BackupPath%%BackupFile%"
