Abstract: 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.

Abstract: 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.

Abstract: A computer-implemented method according to one embodiment includes receiving, at a virtual file system, replicated data from a physical file system, transferring the replicated data from the virtual file system to cloud storage, and providing access to the replicated data in response to an unavailability of the physical file system, utilizing the virtual file system and the cloud storage.

Abstract: Methods that can accelerate replication of file metadata on different sites are disclosed herein. One method includes recreating, by a processor, a transaction history for a predetermined period of time for a set of consumer sites of a first storage network and synchronizing data in the set of consumer sites and a new consumer site added to the first storage network utilizing a cloud scale persistent message bus. In this method, the data is synchronized based on the recreated transaction history during the predetermined period of time and current transactions performed on each consumer site in the set of consumer sites. Apparatus, systems, and computer program products that can include, perform, and/or implement the methods are also disclosed herein.

Abstract: A computer-implemented method according to one embodiment includes identifying data stored within a first virtual storage tier of a storage system, analyzing one or more characteristics of the data, and conditionally transferring the data from the first virtual storage tier of the storage system to a second virtual storage tier of the storage system, based on the analyzing.
