What is remote blob storage?

Remote Blob Storage (RBS) is a feature in Microsoft SharePoint that allows organizations to store large binary data, such as images, videos, and documents, in external storage systems instead of directly on the SharePoint content database. This helps to reduce the size of the content database and improve the performance of SharePoint.

RBS works by storing the content data in an external storage system, such as a network-attached storage (NAS) or a cloud storage service, and storing only the reference to the data in the SharePoint content database. When a user requests the content, SharePoint retrieves the data from the external storage system and presents it to the user.

Remote Blob Storage can be enabled at the site collection level in SharePoint and is particularly useful for organizations that have large amounts of binary data that need to be stored and accessed in SharePoint. It helps to improve SharePoint performance and scalability by offloading the storage of large binary data to external systems.
