Since we cannot confirm the necessary operating system permissions, the default installation package does not include the Auto Backup feature.

If you need the Auto Backup feature, you can download the backup utility from the following URL:
https://www.bistonesoft.com/AutoDB.exe

After downloading, you can place it in your server application’s installation directory and schedule it to run using the server's Task Scheduler.
The command to run it is as follows:
AutoDB.exe "E:\Bistone Hotel Management System\Backup\BiHMS.sql"
Here, "E:\Bistone Hotel Management System\Backup\BiHMS.sql" can be replaced with the directory and filename you wish to back up. And, if your path contains spaces, please enclose it in double quotation marks.

As shown in the image below:
Here, E:\Bistone Hotel Management System Full Board Version\Server\ is our server application's installation directory.
