Service description:

CERNBox provides synchronisation capabilities between a user machine (desktop PC, smart phone or tablet) and a central repository, managed by CERN IT department. Currently it provides a functionality analogous to DropboxTM or similar system.

The data are stored on EOS, the disk-storage provided by the IT department for LHC computing. This allows users to access data via lxplus/lxbatch and, via synchronisation, from their mobile devices. The sync and web access layers are based on OwnCloud (

Every user of CERN computer services has access to CERNBox (same username and password as for nice/lxplus). The initial quota has been set to 1 TB per user. Same conditions and limitations apply, as for the other CERN computing services (CERN Computing Security).
