Home share

Local Home Share

With your science account you automatically receive a home directory.

The home directory is backed up by C&CZ, and is general accessible  :

• home directory on C&CZ linux servers (shared using nfs protocol)
• H: drive on C&CZ managed pc's running windows (shared using smb protocol)
• on any other host you can mount it as a network disk :
  You need to attach the network share using your science account :
  • Windows: \\<Server>\<ScienceAccount>
    Note: when asked for credentials with a login popup window, and this popup window shows it is using a different windows domain than B-FAC,
    then you can also specify the windows domain in the user field as: B-FAC\<ScienceAccount>
  • Linux/Mac: smb://<Server>/<ScienceAccount>
• Where <Server> is one of :
  • pile.science.ru.nl
  • bundle.science.ru.nl
  • pluri.science.ru.nl
• To find out which you need to use you can login to https://dhz.science.ru.nl/index?Language=en where you can see at the main page which server to start under the heading "Home disk at".

quota

The space is limited by a quota. Questions about the size and used space of your quota can be answered :

• on linux by using the 'quota -sQ' linux command on one  of the  linux servers  lilo1.cs.ru.nl or lilo2.cs.ru.nl of C&CZ.
• on windows you can see the soft limit of your quota by looking at the properties of the home share.

If you are over quota than you automatically get the following email from C&CZ:

 Warning: You are over quota on your network home partition on the server pile.science.ru.nl.
 Above you find the disk usage, the number of saved files and the quota limits.
 You are adviced to clean up disk space by removing redundant files.
 To see how the disk usage is distributed over the directories, use:
  
   Using Linux  : du -sk * .??* | sort -n
   Using Windows: WinDirStat  (on managed PCs it can be found in S:\\windirstat)
   
 For additional info: please contact C&CZ, postmaster@science.ru.nl, phone 53535.

A bigger quota can be requested by contacting one of the scientific programmers

Example: check quota on linux

 jan@lilo2:~$ quota -sQ
Disk quotas for user jan (uid 4111):
Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
pluri.science.ru.nl:/home-pluri-30/thchem
             382M    489M    538M            2938   50000   55000

 jan@lilo2:~$ du -sh ~
382M    /home/jan

Thus the user jan :

• has 382 Megabyte in use scattered over 2938 files
• has a quota of 489 Megabyte and a maximum number of 50000 files
• for a limited time he is allowed to use upto 538 Megabyte and 55000 of files
• so the user jan is not over quota

SURFdrive

IMPORTANT: university policy forbids you to put critical data on surfdrive. Read the policy here!

SURF introduces SURFdrive. SURFdrive is a personal cloud storage service for the Dutch higher education and research community, offering staff, researchers and students an easy way to store, synchronise and share files in the secure and reliable SURF Community Cloud.

SURFdrive is the alternative to commercial cloud storage services like Dropbox and now available to Radboud University staff. All RU staff have up to 100 GB of secure storage on the SURF community cloud, and can share the content of this storage with other SURFdrive users as well as guest users. You can also synchronise your data on SURFdrive across multiple devices. SURFdrive is primarily intended for storing work-related files. Please do not store personal files on SURFdrive.

In the SURF community cloud, every user has a virtual drive on which files can be accessed anytime, anywhere. This personal cloud storage service has been specially developed by SURF for employees and researchers in the Dutch higher education and academic research sectors. Data is stored within Dutch borders, the users remain the owners of their own data, and SURF itself provides no information to third parties.

SURFdrive is user-friendly and accessible from any standard computer, smartphone or tablet. Files can be uploaded and shared through a simple web interface: http://www.surfdrive.nl.

Select 'Radboud University' and log in with your u-number and RU password.

To synch data on SURFdrive with data on your workstation, you need the SURFdrive client. Use the request form on http://www.ru.nl/surfdrive to request the client for your RU workstation. If you do not have a PC or laptop administered by the ISC, you can install the software yourself after downloading it from SURFdrive.

• Anywhere and anytime access to your files: from your smartphone, your tablet or your laptop.

Functionalities https://www.surf.nl/en/services-and-products/surfdrive/surfdrive.html

• offline synchronisation, ensuring that users have access to their files at all times
• easy and secure file sharing within the higher education and research community
• users can invite guest users to share documents
• optimised for smartphone and/or tablet use
• 30-day backup and recovery
• 99.5% availability, with 99.9% availability from mid 2015

About backup:

• The SURFdrive web-environment has a recovery option to restore data from 30 days back. This is a sort of Trash which is only available through the web-environment.
• For calamities there is an offsite replication of all data. In case your laptop gets stolen and by coincidence there is also a fire at the datacenter then your data is still stored securely on a second site.
• Note: this means if you by accident throw away a file it will be really gone after 30 days, so it may be still wise to make from time to time your own local copy to still be able to recover from such incidents.
