ABSTRACT:
A package of local files are maintained in a first local computing device and a descriptive record of the local files is maintained in a second local computing device. A directory-modified-date parameter within the first local computing device and a file-modified-date parameter in the second local computing device, but updated in accordance with a local clock from the first local computing device, are used to maintain the descriptive record in the second local computing device synchronized with changes to the local files in the first local computing device. Copies of the descriptive record and package of local files are maintained in a remote computing system. A first package-modified-date, PMD, parameter in the second local computing device and a second PMD parameter in the remote computing system are used to maintain the copies in the remote computing system synchronized with those in first and second local computing devices.
