This month we are happy to celebrate the fifth birthday of our tool KEEPER, allowing you to sync & share your project data while being properly archived in the Max Planck infrastructure. With KEEPER, MPDL has been providing its users with storage and many collaboration functionalities, making daily work and research easier and becoming a reliable and secure service for five years now. Over 4000 users, 145.3 TB used storage, and around 65.5 Million shared files show the impact KEEPER has made in the daily workflow of MPG scientist, employees, and their cooperation partners. We are looking forward to many more years of organized research data! Happy Birthday, you are a real KEEPER!
