NAS Data Storage Service - overview
The NAS (Network Attached Storage) service allows staff and students in Trinity to store non-sensitive data on a central network server, to provide a secure central access point to a large set of data with round-the-clock availability. This centralised data can be securely shared out to selected staff and students by managing the relevant permissions, based on their Trinity username. NAS data storage folders can be connected to by the approved end users from any computer connected to the Trinity network and from computers connected via the staff VPN service, which allows staff to connect to the Trinity network when off site.
Requesting NAS storage
Requests to setup NAS data storage can be made by registered Trinity staff via the NAS data storage request form. Consultancy with the requester to determine initial requirements will be provided where required.
Who can connect
NAS storage can be accessed by registered Trinity staff and students. During the request process you will be asked to provide the approximate number of staff, postgraduates, and undergraduates who will require access to the NAS. It is not possible to provide access to non-Trinity users.
Where you can connect from
NAS storage can be accessed only by registered Trinity staff and students and only from the Trinity 'wired' network in offices and labs, from the staff wireless network and from the student networks and via the VPN service for staff.
Supported operating systems
The following operating system versions are supported:
- macOS Big Sur (11.x) or later - See supported versions
When requesting Network Attached Storage you will need to specify the length of time required, the storage space requirements, and data backup and recovery options.
The cost of service will be calculated on the basis of your selections.
Length of time
You can choose to have the storage setup for between 1 and 5 years, with the option to request an extension of the time as you approach the end of the initial period.
Storage space requirements
You can select data storage size between 50GB and 3000GB (3TB). Requests for larger storage space requirements will be discussed with the requester.
Data backup and recovery options
You can opt for IT Services to include your storage in a scheduled weekly or daily backup for an additional cost. If you are using this service to store your own data backups, then it is likely you will not require this further backup option.
If you select a data backup option, you are entitled to 5 recovery requests within a 5-year period, with further data recovery requests incurring an additional cost. Data recovery requests will be processed within 3-5 days.
The backups for the previous 21-day period are retained. In the case of a weekly backup, there is one backup taken every 7 days (3 backups in 21 days) meaning data may be retrieved from the last full backup, as opposed to the daily backup option (Mon to Fri) which provides recovery from the previous nights backup. For both types of backup you can recover data which is 3 weeks old.
Backups are held on campus for the first week, and then moved to an off-site location.
The precise costs differ depending on the amount of storage space required, how long it is required for and which data backup and recovery option is selected. A full quote is provided after submitting a request, based on the options selected on the request form which is available further below. Please note that pricing is subject to change with alterations in the back-end infrastructure. Please read NAS Terms and Conditions for more details. Below are some sample costs:
- Costs for 100GB storage with daily backup for 5 years is €1,064
- Costs for 1000GB (1TB ) storage with daily backup for 5 years is €6,652

Further information on Data classification can be found at our Data Classification page
Setting permissions and creating subfolders.
Users requiring access will be assigned to an Active Directory (AD) group to facilitate assignment of permissions. IT Services will setup the AD Group and assignment of initial share permissions for relevant access for the group. The administrators/technical contacts will be asked to provide a list of users that will be added to the group. The administrators will specify if the group should have read or read and write access. Only the administrators can request new users to be added to the group by forwarding a request to ITServices.
The nominated local administrators/technical contacts will be responsible for the creation and modification of subfolders within the main storage folder, and setting any required permissions on these subfolders, if the permissions are different to those set on the main folder.
The administrators can overwrite any pre-set permissions using instructions provided on the Managing File Access page. Setting permissions works only from Windows PCs.
Expiry or Termination of service
Expiry of current period of subscription
If no contact has been made after the agreed period of subscription, IT Services will assume the service is still required. As costs for the underlying infrastructure may have changed, the relevant department will be notified of any changes to billing at the time of invoicing.
Termination of service
When the service is no longer required then notification of requirement to terminate the agreement should be requested through the IT Service Desk by the nominated local administrator or technical contact. Data can be migrated from the storage to other media at the request of the nominated local administrator or technical contact.
It is the responsibility of the nominated local administrator and technical contact to transfer the data to their own media if they wish to retain a copy locally e.g. on their own machine. The requester has 3 weeks from the date of notification to copy the data before IT Services delete the data as data will be deleted by IT Services 3 weeks from the date the requester notifies IT Services that the agreement is to be terminated. It will not be possible to refund the charges should the service be terminated early.
