 +However, the progress indicator is not very good and most of the time slows down 
 +the transfers in the purpose of writing to standard output. ​
 +Therefore I suggest you either **redirect the standard error and output**:
 +
 +<code bash>
 +  rsync -avz -e 'ssh -l <​username>'​ --progress source destination &> rsyncoutput.log
 +</​code>​
 +
 +Or even better, use **rsync own log file** instead:
 +<code bash>
 +  rsync -avz -e 'ssh -l <​username>'​ --log-file=rsyncoutput.log source destination
 +</​code>​
 +
 +check the contents of the logfile now and then to see the status:
 +<code bash>
 +  tail rsyncoutput.log
 +</​code>​

-//​Example://​ +If you have and ATLAS dataset, the best is to transfer it to the local 
-<​code>​+LUND Grid storage first, and then to the cluster directly if needed.  
 +To do that you need to submit a DaTRi request
  
-</code>+This page contains all you need to know on how to use the local storage:  
 +http://​www.hep.lu.se/​grid/​localgroupdisk.html 
 + 
 +To move the dataset from any ATLAS grid storage to Iridium, you are recommended to use Rucio, the successor of DQ2. Use the following:​ 
 + 
 +To enable RUCIO tools, you'll need to: 
 +  - copy and configure you GRID certificate on Iridium. 
 +  - run ''​setupATLAS''​ 
 +  - run ''​localSetupRucioClients''​ 
 +  - login to the GRID using ''​arcproxy -S atlas''​ or ''​voms-proxy-init''​ as one would do on //​lxplus.cern.ch//​.  
 + 
 +The RUCIO official documentation is here: http://​rucio.cern.ch/​cli_examples.html
