- | You should avoid doing this. Aurora is not a storage facility, therefore is not meant to be accessed by external sources to do data movement. It is possible to do that through Aurora frontend but this is extremely slow and will slow down your colleagues work. Also, Aurora frontend managers might interrupt your transfers if they see it is taking too much time. I strongly recommend to follow the instructions at [[#Uploading/Downloading data to/from an external source to Aurora]] above instead, and eventually run an ssh/ftp server on your own laptop or workstation, or ask the sysadmin for a convenient form of online storage. | + | For small files (order of tens of gigabytes), small data rates (slow transfers) this can be done via Aurora frontend, you don't need to use ''fs2-hep''. For example, from your laptop: <code bash>''sftp myfile aurora.lunarc.lu.se:/projects/hep/fs2/shared/np/myfolder/myfile'' </code> |

For resources that can be stored on the GRID, you should definitely stage them on the Lund GRID storage instead, a few ways described under [[#Downloading/Uploading data to/from the GRID to Aurora]], so that you can access them from all over the world in the fastest way possible. | For resources that can be stored on the GRID, you should definitely stage them on the Lund GRID storage instead, a few ways described under [[#Downloading/Uploading data to/from the GRID to Aurora]], so that you can access them from all over the world in the fastest way possible. |
