8.2 SmartSync – NAS-to-NAS Data Replication
The NAS server is integrated with the SmartSync function for NAS-to-NAS data replication.
Two or more NAS server are required, one as the SmartSync server, others as the SmartSync
clients. The SmartSync server is like an ftp server. The SmartSync clients can either replicate
their data to the SmartSync server, or copying data from the SmartSync server, depending on
the task settings.
There are three operating modes of SmartSync - “ mirror ” for one-to-one data replication,
“ backup ” for disk-based backup, “ distribute ” for one-to-many data distribution. The following
sections describe the usage and applications of these operating modes.
Building a Mirror Site
Two NAS server are required, one as the SmartSync server, another as the SmartSync client.
It will replicate data from the SmartSync client to the SmartSync server.
On the NAS server which acts as the SmartSync server, create a sync point in it. A sync point
is a folder in the SmartSync server which is exposed to SmartSync clients for data replication.
A sync point of mirror mode receives data from a SmartSync client and builds an identical data
copy in it. To create a sync point, please go to the “Backup → SmartSync → Server” menu on
the “Administration Page”. Click the “Add” button to open the page below. On the page you
should provide the sync point name and specify which group is allowed to replicate data to this
sync point. Set the mode to “Mirror”
