14. Here are more details about these two methods for setup the replication job at the first time Method 1 Skip full copy of replication job for a new clean virtual disk For a new created virtual disk which has not been accessed the subsystem will recognized it and skip full copy automatically when the replication job is created on this virtual disk at the first time Copyright 2004 2013 Qsan Technology Inc All Rights Reserved 155 a Qsan Document User Manual san TIP Any IO access to the new created virtual disk will make it as not clean by the subsystem even though executing Erase function when a virtual disk is created The full copy will take place in such a case Method 2 Use VD Clone function to finish full copy at the first time For a new replication job created on an existing virtual disk with data stored A full copy is necessary to synchronize the volume image between the source and target virtual disks It usually takes a long time to synchronize the data especially when the replication job is running over WAN with limited bandwidth Now QSAN provides an efficient way to let user execute full copy by VD Clone which is a local data copy between source and target virtual disk Then move the physical drives with the target virtual disk to the target subsystem and turn the cloning job into replication with differential copy afterward With this solution user can save a lot of time
