Replication - Buffalo TeraStation User Manual

Replication

Replication is when you copy all data from one TeraStation onto another TeraStation. This allows you to easily create
another backup unit should your main TeraStation ever fail, thus adding another layer of protection for your data. To
initiate replication, simply connect a second TeraStation to your main TeraStation. You can plug in an Ethernet cable
into the LAN port on each unit to link them together. Refer to page 42 for instructions on how to configure replication
settings for each TeraStation.
Normal Operation (Replication State)
Each TeraStation unit has two LAN ports. One can
be used to connect to the network, and the other to
another TeraStation. When the two units are linked,
data on the main TeraStation is fully duplicated on the
second TeraStation on a file-by-file basis. Whenever a
file is created or deleted on the main TeraStation, the
second TeraStation will automatically receive the same
update.
Note:
Replication can also be specified for individual shared
folders, and a maximum of 64 shared folders can be
specified.
If the Main TeraStation Fails
Replication only copies data between two TeraStation
units, but not settings. If your main TeraStation fails, you
may configure the second unit via Settings to enable it
as your main unit.
Rebuilding Replication
After the failed unit is repaired, reconnect the two
TeraStation units via the LAN ports to initiate replication
again with the repaired unit as the new backup.
