You have a few options...for small amounts of data, you can use COPY to backup / restore from csv:

http://www.datastax.com/documentation/cql/3.0/cql/cql_reference/copy_r.html

For larger stuff, you've got the right link. You essentially take a snapshot (which puts it in the folder you mention), and then use something like tar to zip the files and output to a different directory. This is what we're doing in production... we clear the previous snapshot, take a snapshot and tar the folder to a network backup.

Its mean you go to each table in kekpace, tar it and copy it to some other network location.
yes...though with some clever clever use of find, etc. and some regex you can specify all (or a few keyspaces) and do the tarring in one go.
This is the script I'm currently using. Not perfect (probably) but is getting the job done :) github.com/heartysoft/puppet-cassandra/blob/master/files/…
Good idea to provide your script. This is pretty much what we do, too. Nicely done!
