There are a few options researchers can take advantage of when storing their research data. Please take into account the purpose of the storage, appropriate research data management principles, and the data classification when choosing an appropriate storage solution.
Data Classification
Please review the different data classifications that are outlined by the Information Security Classification Standard. There are 4 levels of data classification which are summarised in the table below.
| Level | Description | Example |
|---|---|---|
| Level 1 | Public |
|
| Level 2 | Internal |
|
| Level 3 | Confidential |
|
| Level 4 | Restricted |
|
When selecting a storage option, you must use one that meets or exceeds the rated security classification.

Research Data Management
We recommend you follow good Research Data Management (RDM) practices and ensure you have a Data Management Plan (DMP) created to guide your data's life-cycle. Your DMP can help us support the FAIR (Findable, Accessible, Interoperable, and Reusable) principles for data management.
Please consider contacting Libraries and Cultural Resources for assistance.

ResearchFS
ResearchFS is a University of Calgary-hosted SMB/CIFS storage solution funded and operated by RCS. It is available by request to faculty and staff with active research data.
| Capacity | 1TB with quota increases available on request. |
|---|---|
| Classification | Level 1 - 2 |
| Request Access | Visit ServiceNow to request access |
Service Description
You may use ResearchFS to store your active research data files. ResearchFS is intended to be used as a research group or project share. ResearchFS is available on campus or off campus using the IT supported VPN client. Information on how to download and install the VPN client can be found here: https://ucalgary.service-now.com/it?id=kb_article&sys_id=880e71071381ae006f3afbb2e144b05c (IT account login may be required). All ResearchFS users must have a University of Calgary IT account.
Data recovery
ResearchFS does daily snapshots at a bit past midnight, which it keeps for 30 days. You should be able to recover a deleted file for up to 30 days, if it was in your share overnight. If you create a file and delete it during a day, no snapshot will be available for you to recover. ResearchFS presents backups using the windows OS 'previous versions' functionality. If you are not familiar with using this, or if you are on a Linux or MacOS device, you can request a restore, with Service Now.
For backup, we replicate changes to a distant data center every hour. The storage hardware which hosts your data is located in the basement of the Math Sciences building and our backup is in the HRIC building, so in case of an on campus disaster, your data should be safe.
Support for ResearchFS
If you have questions, please contact the IT Support Centre.

ARC Cluster Storage
ARC storage is used to support workflows on the ARC computing cluster. The expectation is that storage on ARC will only be used for active and upcoming computational projects. It is not suitable for long-term or archival storage as it is not backed-up and is not guaranteed to be available for the time periods that are typical of archiving. ARC is a research cluster, which means it has high performance but can be stopped for required maintenance when needed. Thus, ARC cannot be relied on for any kind of service that requires constant availability. Which means, in turn that ARC's storage cannot and should not be used as a main storage facility for research data. The master copy of research data should be stored elsewhere and only part of that data are expected to be copied to ARC for computational analysis.
ARC Home Directories
Every user account on ARC has a static 500GB allocation of storage and a maximum of 1.5 million files (including directories). This cannot be increased or decreased. Home directory storage is connected via a network file system to the rest of the cluster and supports fast data transfer to memory on compute nodes. This also means that basic file system commands (like ls, find, and du) take longer to run as the number of files in your home directory increases. In particular, we strongly encourage users to stay under 100000 files if it is at all possible. This can be achieved by combining smaller data files into single larger files, using structured data formats rather than large number of text files, or combining collections of files that will be used together into archives (tar, dar, etc). Since top level permissions on home directories are set to prevent other users from reading or executing, home directories are not suitable for sharing data directly with colleagues working on ARC. A Research Group Allocation is a more appropriate place for storing shared data or very large data sets that will be used as part of active computational projects.
ARC /work and /bulk Group Allocation
Any group member who wants to use the shared storage, should send an email to the support@hpc.ucalgary.ca to be added to the access group and CC the PI/ data owner. This will confirm that the PI approves the group member's request access to the shared storage. Please note that the access permissions inside the directory are expected to be managed by the data owners.
All requests should answer the following questions:
- How much storage is requested and why is that the amount that you need?
A rationale for a request can be a formal data management plan or something more informal like a rough estimate to the primary dataset used for a project and a rough estimate to the size of outputs expected from your computations that are planned to run on ARC over the next year.
- What is the requested allocation name? (typically something like <PI name>_lab,
smith_lab, for example) - What is the data classification using the University of Calgary data security classification system?
- Which user or users would be the owner of the allocation? (Full Name and UCalgary Email address, typically the requesting PI but there may be co-PIs)
- Which members of the allocation should be able to request access for new users? (Full Name and UCalgary Email address for active ARC users)
- What is the faculty of the owner or owners?
- Please provide a short description of the lab.
- Please provide a brief numerical estimate of the required storage space based on projects that will use the allocation and their storage requirements .
Example 1: "We will be processing a 1T dataset by performing 100 experimental runs.
Each experiment will be processed to produce a 6GB output, giving 600GB of the total output data.
We will also need 400GB additional space for post-processing and data management.
Thus, we would like to request 2TB of shared space in total."
Example 2: "3 members of our research group need additional shared space on ARC for their independent projects.
Project 1 starts with 100GB of initial data and is expected to generate 800GB of the output results.
Project 2 is going to use simulations and does not use any input data but is expected to generate 2TB of the simulated data for further processing.
The processing will require 200GB of additional space.
Project 3 will be working on a 1TB dataset and is expected to generate about 1TB of the output data.
These projects, therefore, will require 5.1TB of storage.
For convenience of data manipulation and management we would also like to have additional 400GB of extra storage space.
Therefore, we would like to request 5.5TB of shared storage space in total."
Work and Bulk storage can be considerably larger than the home directory allocations. However, there are limits on what RCS can provide as ARC storage provides high-speed access and is expensive to purchase. Typically, any request over 10TB will require some discussion. Work and Bulk allocations differ in a few ways that influence how they are used. Work storage is faster to access as part of computational jobs on ARC although the impact is small for jobs that don't involve enormous numbers of reads. Bulk storage is designed to be a target for instrument data (which is typically processed in a way that reads data a small number of times per job) and is capable of mounting instruments elsewhere on campus using SMB. A number of questions come up frequently about Work and Bulk storage and these are addressed in an FAQ.

OneDrive for Business
OneDrive for Business is a storage solution provided by Microsoft and is available to all faculty and staff.
| Capacity | 5 TB with quota increases available on request. |
|---|---|
| Classification | Level 1 - 4 |
You may use OneDrive for Business to store your personal and work related files. Files stored within OneDrive are by default private only to you but has the option to allow sharing and collaboration with others. OneDrive for Business cannot be used as a department or project share space. There is no group/lab offering with OneDrive.
While OneDrive provides a secure/compliant location from an IT Security stand point, it’s not the most adequate location for data the PI is accountable for 5 years upon completion of the study. This is not a security issue, but a data management issue.
For example, if a study was using a personal OneDrive of one of the researchers to store all the records, and the researcher was to leave the university, this OneDrive would be gone in 30 days.
MS has an automation capability for their O365 products. If you have a windows OS machine, you can use the automation product ‘Flow’ to copy a file to a local file system when a new file is created on OneDrive.
To back up data residing on ARC to your personal OneDrive allocation please see: How to transfer data#rclone: rsync for cloud storage
OneDrive requires Multi-Factor Authentication (MFA) enabled on your University of Calgary IT account.
More information can be located in the following article https://ucalgary.service-now.com/kb_view.do?sysparm_article=KB0032351
University of Calgary OneDrive data is reportedly hosted in Canada (Markham, Ontario).

Commercial Cloud Based Storage Options
Amazon Web Services
Provided by Amazon Web Services, Inc..
- Pricing calculator: https://calculator.aws
AWS provides very many different kinds of services, including storage services.
These options can be a solution for your research needs, but
- it can be expensive, depending on your needs and the amount of data;
- pricing schema is complex and can be confusing for new users;
- the number of options can be overwhelming. A lot of it is designed to provide pricing flexibility, not to increase functionality.
The key points:
- Uploading data to AWS is free.
- Storing data on AWS storage is a paid service.
- Downloading data from AWS storage to your computer is a paid service.
Federated Research Data Repository (FRDR)
The Federated Research Data Repository (RFRDR) is a suitable storage solution for long-term archive storage for research datasets used in published research work. FRDR is a bilingual publishing platform for sharing and preserving Canadian research data. It is a curated, general-purpose repository, custom built for large datasets. FRDR is run by the Digital Research Alliance of Canada.
