polybox is a Dropbox-similar ETH on-campus storage.  The service offers 50 GB of storage on the ETH storage facilities. The service is available to all ETH members and is free of charge.

Please note that polybox is not a functional substitute for the ITS NAS service. In particular, synchronized folders should never contain the original file. The recommended procedure is to edit files at their original location and make a copy in the sync folder which can then be placed in polybox.

The polybox service offers no backup. However, you can recover deleted files with the Web Client (note the instructions at the bottom)
