What methods can be used to copy a file between two servers?

There are several methods to copy a file between two servers:

• scp (Secure Copy) — copies files over SSH, ensuring transfer security.

  scp /path/to/file user@remote_host:/destination/path
  

• rsync — an efficient tool for synchronizing and copying files, supporting incremental copies and compression.

  rsync -avz /path/to/file user@remote_host:/destination/path
  

• sftp — an interactive or scripted file transfer protocol over SSH.

• ftp — a traditional file transfer protocol, but less secure than scp/sftp.

• NFS or SMB — you can mount a remote filesystem and copy files as if they were local.

• curl or wget — if an HTTP/HTTPS server is running on the server, you can download or upload files.

The choice depends on security requirements, speed, and convenience.
