backup missing wireguard/setupVars.conf

When migrating my pivpn settings to a new server the backup did(does) not contain all used settings.

• pivpn -bk
• fresh install of Rapberry PI OS lite (32 bit)
• installed PiVPN via curl ... bash
• restored files as described in https://docs.pivpn.io/wireguard/#migrating-pivpn-wireguard

Behaviour exhibited:

• able to connect, pivpn -c shows an active client,
• client does not connect to the internet

Checked with pivpn -d, no change

Discovered that the pivpnNET (in wireguard/setupVars.conf) was using a different subnet from the original machine.
updated wireguard/setupVars.conf, ran pivpn -d which updated "Iptables MASQUERADE rule", vpn now works for existing clients

If the backup had contained the setupVars.conf and the guide included a couple of extra step frustrations could have been avoided :)
