Shared Filestore

Purpose

To provide areas of filestore which staff can use to share documents, or work in other cooperative ways such as joint authorship, contributory data archives, etc.

Shared filestore is managed by School Computing Officers, who will liaise with ISS when necessary.

Access

An area of shared filestore is accessible to all the staff who have been given access to it by the manager (who is normally the local Computing Officer – see below). However, nobody outside that group (except ISS Systems Managers) has access.

A shared filestore is normally configured ("mapped") once, (often by the Computing Officer for the user), and thereafter it is automatically connected at login.

Therefore, users are often unaware that they are actually using this service: they simply refer to "Drive J" or "Drive M", etc – however the filestore has been set up.

Who has access to our Shared Filestore?

Access is determined by the manager of the share (your local Computing Officer/IT Support staff) and will in most cases by limited to other project, team and local department members. In addition ISS Systems Administrators and the systems which provide the service have access via the built in server 'Administrator and 'System' accounts.' Access for these accounts should not be changed as doing so will  interfere with system backups.

Disabling Administrator access also causes more general problems for the Filestore management systems, and therefore ISS staff may reinstate default permissions without notice.

Quotas (How much space?)

Quotas are negotiated by the Computing Officer with ISS.

Prohibited filetypes

Filescreens are a Windows feature which ISS have implemented on the Shared Filestore. Filescreens allow us to prevent files with specified extensions from being saved there. We do this in order to channel the correct filetypes to the appropriate filestores (ISS provide filestores for various purposes).

All enquiries about filescreening should be directed in the first instance to your local School Computing Officer.

List of Prohibited filetypes

  • .PST (Outlook archive files) are not permitted. Users with PST files should archive them. 
  • .EXE executable files are not permitted.

Other prohibited filetypes

BKF, BT5, BT6, BWA, BWI, BWS, BWT, CDI, CSO, DAA, DMF, DMG, DVD, GHO, GHS, HDD, IMA, IMG, IMZ, ISO, ISZ, MDF,  MRIMG, NRG, OMG, PARTIMG, PARTIMG.BZ2, PARTIMG.GZ, PDI, PQI, PVS, TIB, UDIF, UIF, V2I, VDI, VFD, VHD, VMDK, WIM,

The file servers

ISS's Turret fileservers provide this service; hence the service is sometimes informally referred to as "the Turrets". (See also "Drive J" etc, above.)

Backups and data retention

  • If you have deleted a file, or made a catastrophic change by accident, then the Shadow Copy Service enables you to restore older versions of files, up to a maximum of 10 days old. ISS can assist you in using Shadow Copy for file restoration: contact the IT Service Desk.
  • Although ISS makes backups of the Shared Filestore servers every day, these are for use only by ISS in case of a need for Disaster Recovery: they are not available for the restoration of individual files or folders. Requests to ISS for data restores outside the Shadow Copy window (10 days) cannot be granted. System backups are retained for three months, after which they are deleted.

Service Availability

  • Service is scheduled to be available 24/7/365 with the following exceptions.
  • When system maintenance is carried out this will usually be scheduled for ISS’s normal “At Risk” period, which is Tuesdays 0600-0900.
  • Some systems are automatically re-started for maintenance purposes between 02:00 and 05:00 on Wednesday Mornings, causing an outage of 10-15 minutes.

Notification of service interruptions

  • ISS publish Messages of the Day on the University Home pages; these are part of a comprehensive news publishing system. In the case of filestore and other infrastructure systems, MOTDs are reinforced by email messages sent to individual users who will be affected.

Support

  • All requests for support or advice with the Shared Filestore Service should go first to your local Computing Officer. If this is not possible please contact the IT Service Desk
