Copying data from ssh to local is not that hard:
scp -r admin@servername.com:domains/domain-name.pl/public_html/admin/backups admin/backups
This is how to copy from local to remote:
scp /Downloads/example_file.txt admin@servername.com:domains/domain-name.pl/public_html/admin/backups
You can use "-r" flag to copy full folder. Without this you can copy only one file.
