Abstract: One or more techniques and/or computing devices are provided for replicating virtual machine disk clones. For example, a first storage controller, hosting first storage, may have a synchronous replication relationship with a second storage controller hosting second storage. A virtual machine, within the first storage, may be specified as having synchronous replication protection. Accordingly, virtual machine disk clones of a virtual machine disk of the virtual machine may be replicated from the first storage to the second storage. For example, virtual machine disk clones may be synchronous replicated, replicated by a resync process invoked by a hypervisor agent, and/or stored and replicated from a clone backup directory.

Abstract: One or more techniques and/or computing devices are provided for data synchronization. For example, an in-flight log may be maintained to track storage operations that are received by a first storage node, but have not been committed to both first storage of the first storage node and second storage of a second storage node that has a replication relationship, such as a disaster recovery relationship, with the first storage node. A dirty region log may be maintained to track regions within the first storage that have been modified by storage operations that have not been replicated to the second storage. Accordingly, a catchup synchronization phase (e.g., asynchronous replication by a resync scanner) may be performed to replicate storage operations (e.g., replicate data within dirty regions of the first storage that were modified by such storage operations) to the second storage until the first storage and the second storage are synchronized.
Abstract translation: 提供了一种或多种技术和/或计算设备用于数据同步。 例如，可以维护飞行中日志以跟踪由第一存储节点接收但尚未提交到第一存储节点的第一存储和具有复制的第二存储节点的第二存储的存储操作 关系，如灾难恢复关系，与第一个存储节点。 可以维护脏区域日志以跟踪由第一存储器中未被复制到第二存储器的存储操作修改的区域。 因此，可以执行追赶同步阶段（例如，重新同步扫描器的异步复制）以将存储操作（例如，通过这种存储操作修改的第一存储器的脏区域内的复制数据）复制到第二存储器，直到第一存储器 存储和第二个存储被同步。

Abstract: One or more techniques and/or computing devices are provided for implementing synchronous replication. For example, a synchronous replication relationship may be established between a local storage controller hosting local storage and a remote storage controller hosting remote storage (e.g., replication may be specified at a file, logical unit number (LUN), or any other level of granularity). Data file operations may be implemented in parallel upon the local storage and the remote storage. Independent metadata file operations may be independently implemented from data file operations upon the local storage, and upon local completion may be remotely implemented upon the remote storage. In-flight data file operations may be drained before dependent metadata file operations are locally implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.
Abstract translation: 为实现同步复制提供了一个或多个技术和/或计算设备。 例如，可以在托管本地存储器的本地存储控制器和托管远程存储器的远程存储控制器之间建立同步复制关系（例如，可以在文件，逻辑单元号（LUN）或任何其他级别的粒度上指定复制 ）。 数据文件操作可以在本地存储器和远程存储器上并行实现。 独立的元数据文件操作可以从本地存储上的数据文件操作独立地实现，并且在本地完成时可以在远程存储器上远程实现。 在依赖的元数据文件操作在本地存储器上本地实现之前可以排空飞行中的数据文件操作，并且在本地完成时可以在远程存储器上远程实现。

Abstract: First partial baseline data of a first storage system is identified. First changed data of the first storage system is identified. The first changed data comprises data that has changed since a previous point in time. First backup data is written to a second storage system. The first backup data comprises the first partial baseline data and the first changed data. After writing the first backup data to the second storage system, second partial baseline data of the first storage system is identified. The second partial baseline data does not include the first partial baseline data. Second changed data of the first storage system is identified. The second changed data comprises data that has changed since writing the first backup data. Second backup data is written to the second storage system. The second backup data comprises the second partial baseline data and the second changed data.

Abstract: One or more techniques and/or computing devices are provided for synchronous replication. For example, synchronous replication relationships are established between a first storage object (e.g., a file, a logical unit number (LUN), a consistency group, etc.), hosted by a first storage controller, and a plurality of replication storage objects hosted by other storage controllers. In this way, a write operation to the first storage object is implemented in parallel upon the first storage object and the replication storage objects in a synchronous manner, such as using a zero-copy operation to reduce overhead otherwise introduced by performing copy operations. Reconciliation is performed in response to a failure so that the first storage object and the replication storage objects comprise consistent data. Failed write operations and replication write operations are retried, while enforcing a single write semantic. Dependent write order consistency is enforced for dependent write operations, such as overlapping write operations.

Abstract: Data consistency and availability can be provided at the granularity of logical storage objects in storage solutions that use storage virtualization in clustered storage environments. To ensure consistency of data across different storage elements, synchronization is performed across the different storage elements. Changes to data are synchronized across storage elements in different clusters by propagating the changes from a primary logical storage object to a secondary logical storage object. To satisfy the strictest RPOs while maintaining performance, change requests are intercepted prior to being sent to a filesystem that hosts the primary logical storage object and propagated to a different managing storage element associated with the secondary logical storage object.
