Back-up your data

Summary

If you want to take a copy of the data you collect, you are advised to plug an external hard-drive into the DataDispenser computer during your session. This will collect your data as you go.
The DataDispenser is a small 'headless' (i.e. No monitor or keyboard attached) Linux computer to which USB hard-drives can be connected. It is operated via a web-interface which will enable the streaming of your data directly to a portable disk that you can take with you when you leave.

Instructions

  • 1. Starting DataDispenser at the beginning of your session

    • Plug your external hard drive into the DataDispenser and note the port name.
    • Log in to any computer, and in your chosen browser, enter following url:
    http://[beamline]-dd001.diamond.ac.uk/

    Substitute [beamline] with the beamline you're working on: e.g. http://i02-dd001.diamond.ac.uk (all lowercase)

     

    • Click Define a new Clone (login with your FedID if prompted to do so).
      Each 'Clone' is a unique process for copying the data into the area you specify.

     

    • Complete the online form
    • enter your visit ID (e.g. mt1111-9)
    • choose a Clone ID (letters/digits/-/_ but no blanks)
    • specify the visit data you wish to copy (default: all)
    • (Note: I12 tomography -- you should create separate rawdata and processing clones)
    • select which external hard drive to which you want to copy the data
    • specify the directory name on your external hard drive to copy to

     

     

    • Click Save

     

  • 2. Monitoring DataDispenser during your session

    • Log in to any computer, and in your chosen browser, enter following url:

    Substitute [beamline] with the beamline you're working on: e.g. http://i02-dd001.diamond.ac.uk (all lowercase)

     

     

    • Click your Clone name
      If you see 'Waiting for external media', this means either:
      a) your external hard drive has filled up; or
      b) your Clone does not have an external hard drive assigned to it

    • Plug in your first or additional external hard drive

    • Select your external hard drive (to the right of the 'Add external media' button)
       
    • Click Add external media

    • Click your Clone name
    • Click Finalise
      this does a final pass to ensure all data has been copied

      Wait until the Clone is Terminated (this can take seconds or minutes)

      Refresh the page until the unmount has completed (normally < 1 second)
