File Transfer, Storage, and Infrastructure

File Storage Solutions

Storing documents in the cloud offers large capacity and easy accessibility to your data. Cloud Services are hosted off-campus, using non-university owned equipment that is operated by non-university employees, however they often provide increased functionality at a lower cost than traditional storage services. As with many new solutions, there are several options to consider when switching to cloud storage, and making sure your cloud storage solution is the correct choice for your security needs is very important.

OIT-supported storage solutions include Microsoft OneDrive, UCB Files, and PetaLibrary (for research). Click through the data types below to see recommendations based on the types content you'll be storing.

What storage solution should I choose?

User Data


This includes data for an individual, and can include work documents as well as non-business related data such as a personal music library, personal photos, etc.

Recommended Tools

Microsoft OneDrive

Please note: Google Drive and Google Shared Drives are not suitable for Confidential or Highly Confidential Data, and OIT largely discourages using Google for storage. Learn more about Confidential and Highly Confidential Data.

Department Data


Data that is owned by your department and shared amongst the entire department or teams within the department.

Recommended Tools

UCB Files

Microsoft Teams

Other Supported Tools

Microsoft Sharepoint

Research Data


Research Data includes projects funded by research grants. The data sets tend to be large and generated in research labs and sometimes requires integration with supercomputers. Federally restricted research data, like ITAR and EAR, as well as data including human research data (IRB) and Controlled Unclassified Information (CUI), requires more secure storage procedures.

Before choosing a tool to store research data that falls into the Highly Confidential data standard, contact the Office of Information Security for assistance.
