In the Lite version the Data Replication (Rsync) is not available only in the DSS V6 full or trial version. You could use this then install the Lite key when done copying your data.
We dont provide shell access like the thecus but the Lite supports these protocols and you should be able to copy them over the network or use the DSS V6 Trial version first that gives you 60 days of usage and allows you to use the Data Replication then once done then put back the FREE DSS V6 Lite version.
