     103=== D.4 DISCLAIMER ===
    99104The iRODS service we are offering within the scope of GIMI does NOT guarantee 100% reliable data storage (i.e., we do NOT back up the data). If you are performing your own experiments and want to use iRODS you are absolutely welcome but be aware that we do NOT guarantee recovery from data loss.
