offline node copy

Hi all.

I have running cassandra cluster and i want add new node in new datanenter(need 100% of data).
But i don't want full data copy by network.
Can i copy data manually and then sync new node to cluster?

Something like:
1. Make snapshot on working node and write to external drive.
2. Restore snapshot on new node.
3. Sync
