Abstract: A method, of managing storage of content of a system in storage units including run units which do not allow spin-down functionality and spin-down units which allow spin-down functionality, comprises: establishing a storage tiering rule which sets a policy indicating what content is eligible to be stored on a run unit and what content is eligible to be stored on a spin-down unit, the storage tiering rule being applicable to at least a group of the contents in the content system to determine stored content eligibility thereof for storage in the storage units and migration between the storage units; and identifying candidates of contents to migrate between the storage units, based on the storage tiering rule, state of the content system, and the stored content eligibility of the at least a group of the contents.

Abstract: 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.

Abstract translation: 示例性实现旨在不仅从服务器还可以从连接到服务器的客户端恢复数据。 合并算法以识别在上次备份后创建或修改的内容。 该算法还识别和解决共享文件夹的安装点的更改，防止信息泄漏。 当服务器从故障中恢复时，它会通知客户他们的下一个连接的恢复。 然后每个客户端确定其安装点和文件路径的当前状态，并将其与服务器的安装点和文件路径进行比较。 比较后，客户端通过重命名来理解并指示安装点的差异，并将整个本地数据（所有文件，文件夹，安装点）发送到服务器。 服务器协调差异。

Abstract: 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.

Abstract translation: 本文描述的示例性实现涉及涉及由服务器生成并发送给相应客户端的令牌的事务查询引擎。 客户端使用令牌来查询在服务器上进行的事务。 令牌可以包括详细描述文件系统的共享和私有信息的安装点信息，标识文件系统的事务的事务标识符以及用于标识对应的文件系统的文件系统标识符。 服务器处理此令牌，并根据文件系统的事务信息更新令牌，并将令牌发送回相应的客户端。
