While this will work perfectly well, this command is a waste of
resources. The compression ("-z") makes locally no sense, and there is
no need to tar the data (which will basically just concat files). You
will get the exact same result with
# cp -a /source /destIf the FS has been formatted before, no fragmentation should occur in every scenario, as long as no parallelism is used while copying, because each file will be created and filled with data one after another. Bye, Daniel
