How Offsite Copy works

About using a network server as your Offsite Copy destination

Each time you plug in either drive A or B, the latest recovery points are added to
the drive. This method gives you multiple points in time for recovering your
computer in the event that the original backup destination drives fail or become
unrecoverable.
Using external drives as your Offsite Copy destination ensures that you have a
copy of your backup data stored at two separate, physical locations.
You can also specify a local area network server as an Offsite Copy destination.
You must be able to access the server that you plan to use. You must either map
a local drive to the server, or provide a valid UNC path.
For example, suppose that you set up a local external drive as your first Offsite
Copy destination. Then you identify a server that is located at a second physical
location from your own office. You add the remote server as a second Offsite Copy
destination. As backups occur, recovery points are copied first to the external
hard drive, and then to the remote server.
If the remote server becomes unavailable for a period of time, Offsite Copy copies
all recovery points that were created since the last connection. If there is no room
to hold all of the recovery points available, Offsite Copy removes the oldest
recovery points from the network server. In turn, it makes room for the newest
recovery points.
