This example shows how to use the backup/restore feature for the Velobox' client database. (See HTML source for details.)
Uses a simple ancor (<A ...> ... </A>) with href="/db_buprest". For storing, a filename with the current date will be proposed.
[Backup Velobox data]
Uses a multipart/form-data form with a file input tag.
If the Velobox cannot restore the data, the HTTP error "400 Bad Request" will be returned.
Hint: The Velobox is unable to handle multiple parts or a part other than type="file".
(May not fit very well in a web application.)
