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.

Distributed disaster recovery file sync server system

Example implementations described herein are directed to a transaction query engine involving a token that is generated by the server and sent to the corresponding the client. The client uses the token to query transactions made on the server. The token can include mountpoint information detailing shared and private information of the filesystems, transaction identifiers identifying transactions of a filesystem, and a filesystem identifier to identify the corresponding filesystem. The server processes this token and updates the token based on the transaction information of the filesystem, and sends the token back to the corresponding client.
