Computer-implemented methods for prioritization of data restoration based on recovery time objectives are provided. Aspects include receiving a request to store an object in a primary data volume, the object being associated with an application operating on a virtual server instance, appending an extended attribute to the object, and storing the object with the extended attribute appended in a primary storage device. Aspects also include periodically backing up the primary storage device to a cloud object storage device and transmitting a restore request to the cloud object storage device based on a determination that the primary storage device has become unresponsive. The restore request causes sequentially restoring a plurality of objects corresponding to primary data volume in an order based on the extended attribute appended to each of the plurality of objects.

Prioritization data restore based on recovery time objectives

A computer-implemented method according to one aspect includes determining and storing characteristics of a plurality of cloud vendors; dividing a workload into a plurality of logical stages; determining characteristics of each of the plurality of logical stages; and for each of the plurality of logical stages, assigning the logical stage to one of the plurality of cloud vendors, based on a comparison of the characteristics of the plurality of cloud vendors to the characteristics of the logical stage. Data migration between the cloud vendors is performed during an implementation of the workload to ensure data is located at necessary cloud vendors during the corresponding tasks of the workload.

Implementing workloads in a multi-cloud environment with data migration between cloud vendors

A computer-implemented to control access to data on an off-premises storage system. The method includes defining an access policy for a plurality of files in a file system stored in an on-premises storage system. The method further includes registering the access policy with a first off-premises storage system. The method also includes creating a resource-based cloud access policy based on an on-premise access policy. The method includes determining a set of files from the plurality of files to migrate to the off-premises storage. The method also includes obtaining, for the set of files, an access policy as access metadata. The method further includes migrating the set of files and the access metadata to the off-premises storage.

Management of access control in multi-cloud environments

A computer-implemented method, according to one embodiment, is for restoring operation of a data storage system at a disaster recovery site. The computer-implemented method includes: in response to a disaster event occurring at a primary site, receiving an inode list from a cloud storage site, and receiving configuration information from the cloud storage site. The cloud storage site includes a backup copy of data that is stored at the primary site. Moreover, the inode list and the configuration information are used to construct a filesystem at the disaster recovery site. The filesystem at the disaster recovery site does not include a copy of the data that is stored at the primary site, but rather the filesystem includes a plurality of metadata stubs. The filesystem is further used to satisfy I/O commands that are received.

Restoring operation of data storage systems at disaster recovery sites

One or more computer processors to receive an object to store in a cloud storage environment, wherein the cloud storage environment includes a default storage policy. The one or more processors determine whether the object includes a foreign policy as an attribute of metadata associated with the object. The one or more processors, responsive to determining the object includes the foreign policy as an attribute of the metadata associated with the object, determine whether the foreign policy includes storage rules that differ from the default storage policy of the cloud storage environment, and the one or more processors, responsive to determining the storage rules included in the foreign policy of the metadata of the object differ from the default storage policy of the cloud storage environment, store the object based on the storage rules of the foreign policy, and ignore the default storage policy of the cloud storage environment.

Synchronizing storage policies of objects migrated to cloud storage

Methods and systems for automated regulation compliance for backing up and restoring in a storage environment are provided. A system for providing automated regulation compliance for backing up and restoring in a storage environment includes an analyzer module that determines if a storage system complies with regulations. The system includes a converter module that converts the storage system to comply with the regulations in response to determining that the storage system does not comply with the regulations. The system includes a validator module that validates that the converted storage system complies with the regulations.

Automated regulation compliance for backup and restore in a storage environment

A filesystem command is sent by a first processor, and for synchronization by a second processor. The filesystem command is directed to a second object of a second filesystem that is synchronized with a first object of a first filesystem. An expression is sent by the first processor to the second filesystem, and for authentication by the second processor. The expression is generated based on a third object of the first filesystems that is synchronized with a fourth object of the second filesystem.
