I have 100G files in a root directory data/ on Server1 and I need to transfer from this remote machine to another remote machine Server2. SCP is disabled. I have to use "sz" command. This is the first time I use this command.
I need to first log onto Server2, and ssh to Server1, then issue the 'sz' command. What's the right format to use sz to transfer these files under data/ from Server2 to Server1?

SZ is not really the correct tool for the job.
The simplest way to do this is to not use sz at all, but to simply use SSH as a pipe. There are lots of variants, but one way to do this would be to to compress the files into a data stream and write that stream to your local system. This can all be done over SSH (leaving you a compressed backup is as follows:
ssh "tar -cz /data" > /path/to/local/filename.gzIf you want to take advantage of compression, but want the original file, you can do something like
ssh "tar -cz /data" | tar -xf Which will compress the file into a stream, send it across the connection and decompress it.
