About manual transfer replication
If you are transferring a large amount of data and your network link between the primary and secondary groups is
not sufficient, you can use manual transfer replication for a replication operation. Manual transfer replication
requires manual tasks and uses external media to copy data to the secondary group, instead of using the network.
For example, the first replication of a volume copies the contents of the volume to the second
ary group. If in-use
volume space is large and the network is slow, the replication operation can take a long time. In this case, you
might want to use manual transfer replication.
You also might want to use manual transfer replication after you defragment a lar
ge volume.
Manual transfer replication should only be us
ed when necessary. A properly constructed and sized network should
be able to handle network replication.
