Can´t make a backup from virtual machine

Hi there!
Im looking forward to backup all my progress setting up ERPnext in my VM and restore the backup on a paid server.
Anyway, I searched on how to do this and found two ways:
First from this site https://github.com/frappe/erpnext/wiki/Restoring-From-ERPNext-Backup
anyway I cant get past the first step, this is what the first code line ¨wget [DATABASE BACKUP FILE URL]¨ throws me back.

Any Idea of what I could be doing wrong?
Thanks in Advance!

Very simply, you are pointing to an incorrect address.

Speak to your network administrator about what the address of the VM is , and use the correct url, for example

wget -c 192.123.123.123/path/to/my/file.tgz
