There seems a bug in the lab 10. I have correctly wrote script yet I got an error that there is no file create under backup location of backup server.
It would have helped if you had shared the script you ran to copy the zip archive.
#!/bin/bash
zip -r /tmp/xfusioncorp_media.zip /var/www/html/media
scp -r /tmp/xfusioncorp_media.zip clint@stbkp01:/backup/
To copy the archive, you might have to generate an SSH key pair and copy it to stbkp01 server.
