DietPi | Lightweight justice for your single-board computer

i run a mixed windows and linux network with different desktops, notebooks and raspberry pis. i am trying to establish an off-site backup between a local raspberry pi and an remote raspberry pi. both run on dietpi/raspbian and have an external hdd with ntfs to store the backup data. as the data to be backuped is around 800GB i already initially mirrored the data on the external hdd, so that only the new files have to be sent to the remote drive via rsync.

i now tried various combinations of options including --ignore-existing --size-only -u -c und of course combinations of other options like -avz etc.

the problem is: nothing of the above really changes anything, the system tries to upload all the files (although they are remotely existing) or at least a good number of them.

could you give me hint how to solve this?

I'm trying to run a script automatic when booting Raspberry with DietPi. My script starts a Python3 programm which then at the end starts an external program MP4Box which merges 2 video files to a mp4 in a folder in my lighttp webserver.

When I start the script manually everything works. But when the script starts automatically on boot, when it comes to the external program MP4Box, I get an error:

I want to use my raspberry for two purposes:

• Tor proxy
• Email server

So, the tor proxy is already set and I was able to use it. I installed the tor services on my DietPi distro, I configure the proxy on my browser, port 9050 socks v5, and everything is cool. I decided to install the email server but, first, I was setting up iptables as firewall. I was following a tutorial for the setting and I copied and paste the rules. Anyway, even if I comment the rules when I set the proxy in the browser I can not reach anything, I got a timeout. If I remove iptables, uninstall it, the proxy works again. If i run a

iptables-save

this is what I got

i want to run a python script on dietPI. I chose dietPI because i want to boot fast.
