    Abstract: Method and system for performing recovery for a replicated copy of a storage space presented as a logical object is provided. An attribute associated with the logical object for enabling the recovery is set and when the storage space is replicated the attribute is stored as metadata for the replicated copy of the storage space. Based on the attribute, a clone of the logical object is presented as a writable option to write to the first replicated copy. After the write operation where information is written to the clone, a second replicated copy with the clone information is created. The clone is deleted after the second copy is generated.

    Abstract translation: 提供了用于为呈现为逻辑对象的存储空间的复制副本执行恢复的方法和系统。 设置与用于启用恢复的逻辑对象相关联的属性,并且当存储空间被复制时,该属性被存储为存储空间的复制副本的元数据。 基于该属性,逻辑对象的克隆被呈现为写入第一个复制副本的可写选项。 在向克隆写入信息的写入操作之后,创建具有克隆信息的第二个复制副本。 生成第二个副本后,克隆被删除。

    Abstract: Methods and systems for protecting virtual machines is provided. One method includes discovering, by a first plugin, from a virtual machine (“VM”) management system, a plurality of VMs that share a logical data store having a plurality of virtual volumes used for storing data for the VMs by a storage system registered with the first plugin and a virtual appliance of the VM management system; obtaining, by the first plugin, from the virtual appliance, metadata and storage layout of a set of virtual volumes used by a VM to store data; using a first application programming interface (API), by the first plugin, for identifying a first set of storage volumes used by the storage system to store data for the set of virtual volumes; and creating, by the first plugin, a consistency group (“CG”) having the identified the first set of storage volumes and generating a snapshot of the CG.

    Abstract: Methods and systems for storage services is provided. One method includes configuring by a processor, a database availability group (DAG) storing an active database copy at a first computing node and a passive database copy of the active database copy at a second computing node; initiating a backup operation for backing up the passive database copy from the second computing node; and interfacing with the first computing node by the second computing node for completing the backup operation. The first computing node identifies logs for the backup operation, backs up the identified logs and provides metadata associated with the backup of the identified logs to the second computing node. The second computing node updates metadata for the backup operation such that a backup copy of the passive database copy points to the second node with metadata received from the first computing node.

    Abstract: Methods and systems for a distributed database cluster storing a plurality of replicas of a databases are provided. One method includes locating by a processor, a timestamp of a last stored record in a backup copy of the database from a plurality of logical partitions for a point in time restore operation; identifying by the processor, an operation log for each logical partition with the last stored record, the operation log providing transaction details associated with the database; splitting by the processor, the operation log for each logical partition by ignoring transactions that occurred prior to the timestamp of the last stored record; and using by the processor, the split operation log for restoring the database to the point in time.
