Transfer all files older than 33 minutes via FTP

I want to check a local directory and transfer all files older than 33 minutes via FTP to another computer. Possibly the transferred files should be moved to a local directory "backup" (optional). However, I have 0 experience how to create such a script. Is there someone who can create such a script for me ? I tried with the code generator but it does not help here.... :-(

I am grateful for any help !

This should do:

OK. So far it works already. Thank you for this!!
Would there be a possibility to move the sent files to the local computer ? \Backup\* or something like that?
Or another way out, delete the files after sending? (but is less desired!)
The problem is: On the other side runs a program that enters the files into a database and then deletes them. I then move the old plus a few new to the server and he processes them again (which is actually no problem) but the files there then more and more and I can only 200)!

Deleting the uploaded files is easy. Just add -delete to the put command.

Moving the uploaded files is more difficult.
Native transactionally-safe support in scripting is tracked here:
Issue 2153 – Moving transferred files to another folder in scripting
You can vote for it in the tracker.

Until that is implemented, see
