Abstract
Methods for maintaining consistent data and attributes for files sharable by two or more consumers are provided. One exemplary method includes initially defining a set of consistency bits that are implemented by a file consistency protocol. Once the consistency bits are defined and implemented by a file system managing the shared files, the method receives indication that a change was made to a file associated with the file system. The method then sets a bit of the set of consistency bits on each instance file to reflect the change performed to the file. An update is then messaged to each instance file such that the instance files contain the change made to the file. The messaging can be performed by way of a pulling protocol or a push protocol, which transfers the updates to the instances to maintain the consistency.
