The diskspace on C&CZ servers can be used from all kind of C&CZ servers and personal computers, but also from other PCs or even from home with WinSCP or VPN. Almost all disks that are managed by C&CZ, are being backupped regularly, in order to be able to restore data in case of small or large calamities.

  • Every user with a Science login has or is entitled to an amount of disc space of a few hundred megabyte on a server. This disc space is called the "home-directory" on Unix/Linux computers and the "H-drive" on Windows-computers.
  • Diskspace for groups/institutions: there are two RAID arrays with 90 GB partitions, that can be rented for 135 euro per year. One or more folders on such a partition can be mapped as a network drive on Windows PCs or NFS-mounted on Unix/Linux hosts. The ability to read and/or write files on these folders can be limited to a group of logins.
    C&CZ has bought a 3 year support contract for these RAID arrays, through which a failure can be solved within 8 hours during business hours. Because it is a RAID-array, the failure of 1 single disk will not give a disruption of service for users. The partitions are backed up (daily and incremental). Even in the case when the whole computer room is lost, data can (eventually) be restored. Take note: the more expensive RAID arrays on which C&CZ stores the home directories of users are even more reliable and have a 4 hour support contract even outside of business hours.

  • To cooperate (share files etc.) with other employees and students of other universities Surfgroepen can be used for free, even external persons can join.
