How can I reduce the time that it takes to backup through a VPN?

I perform a backup of certain network drives three times a week. This backup used to take several hours (overnight), but now it takes roughly 20 hours. Most of the network drives are located in-house, but one is located in another location roughly one mile away. This remote location is linked to the main location by a VPN connection. According to the report, the backup of this particular network drive takes 13-14 hours. The amount of data on remote network drive is 5 GB. The VPN connection is controlled by two Sonicwall TZ190 firewalls. This has been happening for several months. Thanks.

What is the speed of the WAN link between the sites?

Is this with or without data verification?

Are there any content filtering features running an any of the TZ190's?

Also I would suggest you move to a differential backup Mon-Thu and a full backup on Fridays. This would drastically help reduce the amount of data you are backing up.
