How to transfer many files from one server to another?

Question

linux

There are two servers on ubuntu, one of them has a lot of small files of 50-100kb each, their total size is about 2 TB, how can I transfer them to another ubuntu server?
Just archive and transfer will not work, there is no free space for the archive. And if you try, for example, through WinSCP, open one server in the left window, and another in the right window, then the files will be transferred one by one at a speed of 50kb~.

Answer 1

And what does WinSCP have to do with it if you have 2 servers on Ubuntu? Throw directly from one to another via rsync

Answer 2

rsync

Answer 3

rsync.
ftp

Answer 4

Set up key access and use rsync
For speed, you can specify settings in .ssh/config
so that a socket is used - then the data transfer speed will be much higher
