In any computer system a critical part is storage and today´s increasing demand for storage space require a flexible filesystem that offers the required scalability and supply the features that system administrators require to maintain data in safe and error-free way e.g., that data is correct and free from bit rot. Another consideration is that performance is important for the overall experience. Two file systems that are good candidates are Btrfs and ZFS. This work examines articles from 3 databases through a literature review, extract experiences and lessons learned from implementation and use of the two file systems. The literature study indicates an overall positive experience with several benefits. However, most of the articles contained experiences from the implementation and use of ZFS and BtrFS fall into its shadow. The study also tells the importance of thorough research before implementation to weigh the pros and cons.
