Explanation:

WAN Backup over the Internet
Another alternative for WAN backup is to use the Internet as the connectivity transport between
sites. However, keep in mind that this type of connection does not support bandwidth guarantees.
The enterprise also needs to work closely with the ISP to set up the tunnels and advertise the
company’s networks internally so that remote offices have reachable IP destinations.
Security is of great importance when you rely on the Internet for network connectivity, so a secure
tunnel using IPsec needs to be deployed to protect the data during transport.
