Syncing files in Norton Zone (mainly windows)

Hi,

 

 I have question.

 I use Norton Zone on 2 device ( windows platform).

 I had synced many files in 1st device say almost  7 GB.

 If I use the same account on different computer it first starts downloading all the 7 GB on to the 2nd device which I don't want.

 Is there a way that we stop downloading the files which is already backed up, and only backup the new files in to the storage in the 2nd device.

 Thanks,

 John.
