An information repository is a collection of interrelated information maintained on a network across multiple servers. Create a unified resource for anyone logged into the system to access when they need information. Many organizations use information repositories to manage their data and can interact with others to share material as needed. The underlying information technology may need to be very robust to handle the volume of information and requests. This term can also be used to refer to a specific type of data management.

The information repository deposits relevant data along with meta-information on a regular basis. Users who wish to access the information can perform a search to find materials relevant to their interests. Repositories can include a variety of information types, including images, video, and text. Users can narrow searches by type to find specific materials. Access is often limited by passwords and other security measures to protect the integrity of the information and limit abuse of the system.
In the sense of a data management approach, an information repository is a secondary storage space for data. When data is no longer needed on a primary server or facility, it can be moved to the information repository for archival purposes. This frees up space on systems in use, without destroying data that might be needed later. The process can be automated to help keep the system running smoothly and ensure that data is transferred regularly rather than randomly.
When data enters a data repository for storage, the system can tag it with relevant information and verify that an identical file already exists. If this happens, the duplicate can be destroyed. The system will store the data for the time indicated. Some are periodically cleaned to free up space, while others can be configured to retain data indefinitely, as long as the data is still useful and the system is still running.
Information repositories are often networked and may include a combination of computers for stability and reliability. They can automate backups to tape, disk, and other media to ensure data is available if needed. Relying on a single data storage location can be dangerous, as any issues there could lead to permanent data loss. Information technology staff can schedule automatic backups as part of routine maintenance to keep the system running smoothly.
