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 Gigabytes on a server. This disc space is called the "home-directory" on Unix/Linux computers and the "H- or U-drive" on Windows-computers. The location of this homedirectory (which server) can be viewed on the Do-It-Yourself website.
|Windows path||\\pile.science.ru.nl\guest204 or \\bundle.science.ru.nl\guest204 check on DIY|
Diskspace for groups/institutions: there are a few RAID arrays with 90 GB or at least 180 GB partitions, that can be rented for 90 and 180 euro excl. VAT per year. Although this is much more expensive than buying 1 disk for 1 PC, it often makes sense, because of the reliability (redundant disks, backup, support contract) and security (stable server). 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 warranty for these RAID arrays and has spares on site, so a failure can be resolved quite fast. 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.
Every now and then you want to send one or more large files (more than a few tens of MBs) to someone else within the Faculty, mail is unsuited for those large files. To make this easy, one can use a network share, where one can store large files temporarily in order to have someone else copy the files from this location. Note that this is expressly meant for temporary storage, we do not make backups of this share, every day we remove files older than 21 days old.
This share can also be used to store temporary files only readable for one self by using the share name \\temp-srv.science.ru.nl\onlyme. Note that also in this case, old files will be removed.
Please create a subdirectory with your name first, and put your files in that directory.
