Whats the best way to finding a File Storing Storage Hierarchy for IT to back up documents through a centralized Repository? We would like to constantly update those documents and upload them so a select number of people can have access to different controls like Viewing them versus updating and uploading, deleting etc. Whats the best way to do this? and whats the best functionality that we can use to achieve this?
