    2 Background T o understand the continuing popularity of portable storage, it is useful to revie w the strengths and weak- nesses of portable storage and distributed file systems. While there is considerable variation in the designs of distributed file systems, there is also a substantial de- gree of commonality across them. Our discussion be- lo ...

    there should be no compromise of robustness, consis- tency or security . There should also be no added com- plexity in sharing and collaboration. Finally , the design should be tolerant of human error: improper use of the portable storage de vice (such as using the wrong de- vice or forgetting to cop y the latest version of a file to it) should no ...

A dif ferent use of lookaside caching for ISR is based on the observ ation that there is often substantial commonality in VM state across users.
