    摘要： Replication of a filesystem or a mount point or share may replicate all data that it consists of irrespective of where the data is stored. Replication protects data irrespective of location. One method is to replicate the filesystem namespace as is while skipping the data outside of the appliance/machine so that replication cost and time are reasonable. The data outside of the machine, like cloud/tape data is protected differently. One example method includes a data protection operation configured to replication a namespace associated with multiple data tiers. During replication, data from one of the tiers is skipped while all of the namespace metadata is replicated. The recovery restores the namespace metadata and the data that was replicated from the other tier. This may be performed in connection with cyber security, for example when replicating multi-tier data to a vault.

    摘要： A storage capacity of a cloud storage system is determined. A recipe contains instructions for reclaiming storage of the cloud storage system. The storage capacity is insufficient to perform the entire recipe. In response, one or more data objects are deleted. A portion of the recipe is executed after the deletion. In some cases, local storage can be used for garbage collection when cloud storage is insufficient to perform even the portion of the recipe. Other embodiments are described and claimed.

    摘要： A method, apparatus, and system determines an optimal storage configuration of storing backup data. The method may include receiving a request from a client device for determining an optimal storage configuration for storing backup data of a client. The method may include determining a cloud utilization pattern of the backup data based on prior access activities and determining a first suitability score for the first storage class based on the cloud utilization pattern. The method may include, for each of the storage classes of the first storage provider, determining a suitability score for the corresponding storage class if the backup data were stored in the corresponding storage class. The method may include transmitting to the client device a recommendation of a second storage class of the first storage provider having a suitability score higher than the first suitability score based on the suitability score to reduce cloud resources usage.

    摘要： One example method includes configuring a data protection environment to include one or more protection targets, applying one or more tags to each of the protection targets, based on the tags, creating a pool that includes some of the protection targets, associating a rule with an SLA that specifies a dataset and a data protection requirement for the dataset, executing the rule to identify a protection target in the pool that most closely meets the data protection requirement specified by the SLA, and defining a data protection policy that includes the data protection target identified by the executing of the rule.
