Title:
FILE SYNCHRONIZATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2013/127147
Kind Code:
A1
Abstract:
The present invention provides a file synchronization system. The synchronization system receives a file transmitted via an access portal by a client, specifies multiple storage paths in a distributed storage system for the file, and stores the file to multiple corresponding storage units according to the specified storage paths. After that, the synchronization system generates a unit file log on each storage unit, generates a system file log at the access portal, regularly collects unit file logs stored by the storage units, and stores the collected unit file logs to a preset storage location. When a file stored in a storage unit needs to be repaired, the synchronization system compares the collected unit file logs and the system file log to determine the file originally stored in the storage unit and another storage unit storing the same file as the storage unit, and copies the file from the other storage unit to the storage unit. The present invention also provides a file synchronization method.
