Backup file getting deleted automatically after 3 days


I have five folders on which I am backing up my database for every day of the week.

If I backup the database to the folder called Monday, after 3 days, the file under Monday gets deleted automatically.
Now I need to find out whether it is a problem with Tamino or my machine. Is there any option in tamino to automatically do this? If so can I change it?

There is a server property called “number of backup generations”. The default is 5 which means that only the last 5 backups are kept - older ones are deleted. You can increase this value to a higher value, max. 4294967295 to prevent Tamino from deleting backups.

Thank you very much for that.
