As part of our contract, Box expressly forbids the university from storing backups or archiving data in CyBox. Customers should limit their usage of CyBox to that which is frequently accessed (days/weeks/months).

To maintain compliance with an overall institutional Microsoft quota, customers should limit their usage of OneDrive to that which is frequently accessed (days/weeks/months).

LSS was designed to specifically address a need for researchers with large data sets and an inexpensive location to store that data. It is not intended to be a live repository, yet to provide researchers with a place to store files that can be downloaded and edited locally. It is not designed for typical file server use.

All storage vendors are moving away from using the term unlimited as they have realized it incurs significant expense. While having no quota, Box does not allow storage of computer backups or archive data. As a result, Box limits the types of data (and how much) is stored there.

Unfortunately, no. Access when using Linux is limited to either the webpage or the community software rclone. Iowa State University does not provide support for the use of rclone, but it does function well for this activity.

Yes. OneDrive has a published limit of 5,000 items per folder. However, your overall account can have millions of files. The 5,000-item limit impacts folder renames or permission changes and may require making changes deeper inside the folder rather than at the very top.

For example, if you have a top-level folder that contains multiple sub-folders, each with 5,000 items, you will not be able to rename the top-level folder because there are more than 5,000 items inside it. You would only be able to rename the sub-folders with 5,000 or fewer items.
