Systems and methods described herein create and schedule remote copy jobs that are distributed among several backup windows, thereby increasing backup service reliability and network resource utilization when copying data from local to remote site. This is accomplished by ranking backup windows by resource availability and proactively guiding a consumer to avoid selecting backup windows that may suffer from a temporal resource scarcity. Recommending suitable backup windows advantageously preserves SLAs by reducing SLA violations that otherwise may occur due to resource scarcity.

Method and system for preventing service level agreement violations in backup-as-a-service

Systems and methods described herein can involve, for a request to create a recovery volume having a specified recovery time objective, identifying a tier from a storage system managing a plurality of tiers that has a restore time that satisfies the specified recovery time objective; and creating the recovery volume in the identified tier of the storage system in response to the request.

Copy data's tier management

Systems and methods described herein can involve for receipt of an addition or modification of a storage device, executing a validation process from one or more managed validation kits according to a remote copy function associated with the storage device, the one or more managed validation kits selected according to one or more feature types associated with the remote copy function; associating the storage device with a corresponding group of storage devices associated with the remote copy function based on information provided by the one or more managed validation kits; and for the association of the storage device with the corresponding group of storage devices and the execution of the validation process being successful, registering the storage device to a storage class associated with the remote copy function.

Automatic storage configuration system

Systems and methods described herein involve a storage system and one or more devices associated with the storage system, the one or more devices external to the storage system, which can include managing a configuration rule difference mapping information that maps configuration detection filter information and required rule manipulation responsive to the configuration detection filter information, the required rule manipulation indicative of a modification to alert properties of the storage system; for detection of a configuration change to the one or more devices based on the configuration detection filter information, identifying one or more rule manipulations from the required rule manipulation information from the configuration rule difference mapping information, and generating a rule manipulation draft to modify the alert properties of the storage system based on the required rule manipulation.

Alert rule manipulation in sync of temporary configuration change

Aspects of the present disclosure involve an innovative method for detecting error zones from a plurality of volume groups. The method may include creating a plurality of probe groups for error detection; detecting a new error associated with the plurality of probe groups and the plurality of volume groups; retrieving error information associated with the new error, wherein the error information comprises an error source, an error type, and an error time; retrieving an error correlation rule associated with the error information; determining if the error correlation rule is satisfied by the error information and information of other known errors; and identifying a common zone based on the error information and the information of the other known errors as an error zone.

Failure area identification system

Example implementations can involve a system, which can involve a server configured to distribute role decision condition expressions created based on user input to one or more storage devices; and the one or more storage devices, which can involve a processor, configured to, for receipt of a request, determine user identification information, request source environment information and requested contents from the request; determine a role from the role decision condition expressions based on the user identification information and request source environment information; and determine whether or not the request can be executed based on the role.

Conditional role decision based on source environments

Example implementations described herein are directed to a method and a system for storage allocation from a storage pool, the method involving, for receipt of a request for storage through an orchestrator communicatively coupled to a management system managing the storage pool, the request comprising user information and request characteristics information, the request characteristics information indicative of a use type for the request, determining a storage tier from the storage pool for the request based on the user information and the request characteristics information; and allocating a pool name and the storage tier in response to the request.
