updating database at remote location

[arun_mrk]

I want my database server(remote location connected thru internet) database to be updated with data from my local system every week.
I want to do using asp.net with c# code(not thru means like sql server replication).
What approach should i follow?
Is Webservices need for this or else is there any need to convert my data to xml format(for speed or security reasons) before updating?
