Abstract: A method for managing storage devices in a backup storage system includes obtaining, by a backup agent, a backup storage initiation request, identifying, in response to the backup storage initiation request, an initial grouping amount for a plurality of application types, generating a plurality of backup storage deduplication pools based on the initial grouping amount, generating a buffer pool, and generating a plurality of deduplication pool metadata mappings based on the plurality of backup storage deduplication pools, wherein a backup storage deduplication pool of the plurality of backup storage deduplication pools comprises a storage device, and wherein the buffer pool comprises a plurality of storage devices.

Abstract: A method for managing storage devices includes, in response to a first determination that a first cloud storage device is inaccessible to a local storage device, obtaining metadata objects from a second cloud storage device, identifying, based on a sync time analysis, at least one metadata object of the metadata objects to be deleted, initiating the deletion of the at least one metadata object on a second cloud storage device, wherein the second cloud storage device is accessible to the local storage device, and updating, after initiating the deletion of the at least one metadata object, a namespace on a local storage device.

Abstract: Methods, systems, and physical computer-readable storage medium are provided to optimize WAN traffic on cloud networking sites. In an embodiment, by way of example only, a method includes fetching deduplication information from a home site to build a repository comprising duplicate peer file sets, one or more of the duplicate peer file sets including one or more peer files, referring to the repository to determine whether a target file corresponds with a cache copy of a peer file of the one or more peer files included in the duplicate peer file sets, and creating a local copy of the peer file of the one or more peer files, if a determination is made that the target file corresponds with the cache copy of the peer file of the one or more peer files included in the duplicate peer file sets.

Abstract: A system for ensuring data integrity, comprising a plurality of data servers configured in a GPFS configuration, the plurality of data servers comprising an application server comprising a application server fileset, a home server comprising a home server fileset and a gateway server comprising a gateway fileset, a connection monitor node (CMN) coupled to gateway server; and logic, executed by the CMN, for monitoring a connection between the home server and the application server; and if the connection is disconnected, executing logic for comparing a duration of the connection disconnect to a expiration timeout attribute corresponding to the application server fileset and if the duration exceeds the expiration timeout attribute, notifying the application server to set an expiration status attribute in the application fileset.
