DISTRIBUTED DISASTER RECOVERY FILE SYNC SERVER SYSTEM

摘要

Example implementations are directed to restoration of data not only from the servers, but also from the clients connected to the server. Algorithms are incorporated to identify content that was created or modified after the last backup. This algorithm also identifies and resolves changes in the mount points for shared folders, preventing information leakage. When the server recovers from a failure, it notifies the clients about the recovery on their next connection. Each client then determines the current state of its mount points and file paths and compares them with the server's mount points and file paths. After the comparison, the client comprehends and indicates the mount point differences by renaming them and sends entire local data (all files, folders, mount points) to the server. The server reconciles the differences.

1. A server comprising:
an interface configured to interface with a plurality of client devices; a memory configured to store information regarding a version of a first file managed by the server at a recovery point, and a processor configured to:
receive a plurality of files from the plurality of client devices to recover files in the server by using the plurality of files in the plurality of client devices, andfor a second file of the plurality of received files having a newer version than the version of the first file at the recovery point, manage the second file as a new version of the first file.
