File transfer program with priorities under Linux?

Question

linux

Good day, dear Habra community!
Can anyone suggest a program for guaranteed file transfer with priorities under Linux?
This refers to software that is capable of transferring a certain list of files, each of which is assigned a priority and a destination address. Of course, the more urgent ones are sent first. If at the time of sending a file with a higher priority arrives, then the transfer of lower priority files is suspended and the sending of the incoming file begins, as soon as it has been delivered, we continue downloading the rest.
The program must be resistant to communication breaks. If there was one, then we just wait until the connection is restored and continue sending.
Well, I would like to have some mechanism that allows you to find out how things are going with the transfer of current files.
Thanks in advance for your reply!

Answer 1

Torrents are quite suitable for these requirements, namely rtorrent - priorities and channel width are regulated, controlled remotely via RPC. And it is possible through nginx with HttpLimitReqModule, or another http. Depends on who initiates the transfer and whether the speed needs to change dynamically.

Try to dig from the side rsync. If you wrap it in a script, you can move mountains.
