Slow copy to the storage

Hi,there is some be copy questions

be 2012

1) There is a topic,solution doesnt help,what else can be make,mb neeed additional options like deduplication or LAN-free backup

2) A separate question on backing up virtual machines.In the default set to use the SAN to move virtual disk data,this option will determine the LAN-free backup for VMware?But the backup time is independent, whether this option is installed.Therefore also requires optimization.
