Yes.
For maximum data protection, in addition to Disk Hero online backup
software, we recommend that you use a firewall and virus protection
software. A firewall protects your incoming and outgoing
connections from abuse by un-trusted software. There are both software
and hardware firewalls. Some of the most popular software firewalls
include Norton Personal Firewall (part of Norton Internet Security),
ZoneAlarm, McAfee, Spygate and Tiny just to mention a few.
Typically
your firewall will not interfere with Disk Hero because the agent is
installed and runs locally. Our software actually initiates the
connection to the data centers from your computer and not by a request
from our data centers.
If
you get a message that Disk Hero could not connect to the data center
(e.g. the connection was refused, the data center is busy or
unreachable, or a dialog box saying "Waiting to Retry", this means that
the Disk Hero software cannot access the internet.
You will need to configure your software firewall setting to allow the following programs to run:
For PCs and USB/U3 drives:
"Disk Hero Agent” (DiskHeroU3.exe)
For Servers:
"Disk Hero Registration" (DiskHeroRegistration.exe)
"Disk Hero Agent” (DiskHeroAgent.exe)
"Disk Hero Remote Agent” (DiskHeroRemoteAgent.exe)
"Disk Hero Server” (DiskHeroServer.exe)
"Disk Hero Executive" (DiskHeroExecutive.exe)
See below for HOW-TO step by step instructions about your brand of software firewall.

backup connection works, you know the firewall or router was the issue,
and you can troubleshoot it further.
