SmartSync – NAS-to-NAS Data Replication
9.5 SmartSync – NAS-to-NAS Data
Replication
The NAS systems are integrated with the SmartSync function for
NAS-to-NAS data replication. Two or more NAS systems 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.
The function of creating sync points of backup mode or
distribute mode are only available on model
4400/4420/8200/8400/8420.
Building a Mirror Site
Two NAS systems 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 system 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” .
