While this will work perfectly well, this command is a waste of |
| 54 |
resources. The compression ("-z") makes locally no sense, and there is |
| 55 |
no need to tar the data (which will basically just concat files). You |
| 56 |
will get the exact same result with |
| 57 |
# cp -a /source /dest |
| 58 |
|
| 59 |
If the FS has been formatted before, no fragmentation should occur in |
| 60 |
every scenario, as long as no parallelism is used while copying, because |
| 61 |
each file will be created and filled with data one after another. |
