Continuous download and upload test

Good day,

Part of my job is device testing, one part of the test that I am doing is to run a heavy download and upload for days. I have cmd code; it is 6 years old (I didn't write it) so I was thinking to run a new version of it using Matlab.

I don't know where to start but the purpose of it is to make sure we have no data disconnection during let us say 7 days. The old script is using put and get from FTP server and capture the disconnection manually (If we know the time, we have tools to check the reason behind the disconnections)

My idea is to run the code which downloads from and upload to FTP server if the device disconnects I receive an email or perhaps record the time in excel sheet.

If you can guide me I will be very thankful (I want to write it for sure, please do not give me the full code).

Thank you in advance.
