D-Link Document – User Manual
Replication
The replication function can replicate data easily through LAN or WAN from one system to
another. The replication operation is as follows. At the beginning, copy all data from the source
virtual disk to target. This is also called a full copy. Afterwards, use snapshot technology to
perform an incremental copy. Please be fully aware that the incremental copy needs to use a
snapshot to compare the data difference. Therefore, enough snapshot space for the virtual disk is
very important. Of course, the replication task can also be set to a schedule.
Create Replication Task
