Replication - Buffalo TeraStation Pro WSS 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.
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 32 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 its settings to
enable it as your main unit.
Rebuilding Replication
After the failed unit is repaired, you can reconnect the
two TeraStation units via the LAN ports and initiate
replication. Once you re-configure the repaired unit,
you can freely choose which TeraStation unit will act as
your main and which will act as backup.
