摘要： Provided are a method, system, and article of manufacture, wherein a data structure corresponding to a set of client nodes selected from a plurality of client nodes is generated. Objects from the selected set of client nodes are stored in the data structure. A determination is made that an object corresponding to a client node of the selected set of client nodes has to be stored. An additional determination is made as to whether the object has already been stored in the data structure by any client node of the selected set of client nodes. The object is stored in the data structure, in response to determining that the object has not already been stored in the data structure by any client node of the selected set of client nodes.

摘要： Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

摘要： In one aspect of the present description, in connection with storing a first deduplicated data object in a primary storage pool, described operations include determining the duration of time that the first data object has resided in the primary storage pool, and comparing the determined duration of time to a predetermined time interval. In addition, described operations include, after the determined duration of time meets or exceeds the predetermined time interval, determining if the first data object has an extent referenced by another data object, and determining whether to move the first data object from the primary storage pool to a secondary storage pool as a function of whether the first data object has an extent referenced by another data object after the determined duration of time meets or exceeds the predetermined time interval. Other features and aspects may be realized, depending upon the particular application.

摘要： A chunk index has information on chunks in a storage space referenced in objects in the storage space. The chunk index includes a reference count for each chunk indicating a number of objects in which the chunk is referenced and a reference measurement representing a level of data object references to the chunk. One chunk is selected to remove from the storage space based on a criteria applied to the reference measurements of chunks having reference counts indicating that the chunks are not referenced in one object in the storage space.

摘要： A system and method for relating files in a distributed data storage environment allows for positive identification of membership of a file within a group, even in a loosely coupled environment where files are not available for comparison in real time. In disclosed embodiments, base files of a client are stored on a server and are accompanied by tokens uniquely identifying the base files. The tokens are generated on the client and may be derived from the contents of the base file using a digital signature. Each file transmitted to the server is accompanied with a token. Incremental backups may be used, and may employ file differencing. Accordingly, sub-files related to the base files may be transmitted to the server for backup. The sub-files are related to their respective base files using the tokens and are cross-linked to the base files so that any sub-files can be retrieved together with the base file from which the sub-file was derived.
摘要翻译： 用于在分布式数据存储环境中关联文件的系统和方法允许对组内的文件的成员资格进行肯定的识别，即使在文件不可用于实时比较的松耦合环境中。 在所公开的实施例中，客户端的基本文件被存储在服务器上，并且伴随着唯一地标识基本文件的令牌。 令牌在客户端上生成，并且可以使用数字签名从基础文件的内容导出。 发送到服务器的每个文件都附带一个令牌。 可以使用增量备份，并可能采用文件差异化。 因此，可以将与基本文件相关的子文件发送到服务器进行备份。 子文件与使用令牌的各自的基本文件相关，并与基本文件交链，以便可以将所有子文件与从其导出子文件的基本文件一起检索。

摘要： LAN-managed storage volumes are managed by a LAN storage manager installed on a storage management server. In processing a LAN-free storage volume request, the LAN tape manager selects a LAN-managed storage volume responsive to the LAN-free storage volume allocation request wherein the LAN-managed storage volume is initialized as a candidate for a LAN-free storage operation. The LAN-managed storage volume may be initialized by the LAN storage manager as a candidate for a LAN-free storage operation prior to the LAN storage manager receiving the LAN-free storage volume allocation request or in response to the LAN storage manager receiving the LAN-free storage volume allocation request. Additionally, prior to being initialized as a candidate for a LAN-free storage operation, the LAN-managed storage volume may be a pre-existing storage volume or a scratch storage volume.

摘要： During execution of an existing scheduling computer program on a client node, an update computer program and a self-describing automatic installation package are downloaded to the client node from a logical depot node implemented on an existing management server. Therefore, advantageously, no physical depot node or other additional computing device is needed for the client node to update itself. Execution of the update computer program is spawned on the client node from the existing scheduling computer program. As such, the update computer program inherits root access to the client node and security credentials to the management server from the scheduling computer program—advantageously, then, a user does not have to perform any laborious configuration of the client node in order to update the node. The client node ultimately updates itself using the self-describing automatic installation package, which includes all the information needed for the client node to update itself.
摘要翻译： 在客户机节点上执行现有的调度计算机程序期间，将更新计算机程序和自描述自动安装包从在现有管理服务器上实现的逻辑仓库节点下载到客户端节点。 因此，有利的是，客户机节点不需要物理站点节点或其他额外的计算设备来更新自身。 从现有的调度计算机程序在客户机节点上产生更新计算机程序的执行。 因此，更新计算机程序从调度计算机程序继承对客户端节点的根访问和对管理服务器的安全凭证 - 然后，用户不必执行客户端节点的任何费力配置，以便更新 节点。 客户端节点最终使用自描述自动安装软件包来自动更新，其中包括客户端节点自身更新所需的所有信息。
