A method and an apparatus for clustering Internet protocol (IP) packets in a wireless network are provided. The method includes receiving, by a network device in the wireless network, a plurality of IP packets from an upper layer of a user equipment (UE) in the wireless network or vice versa, initiating a timer on receiving the plurality of IP packets from the upper layer, forming a cluster of IP packets having a predetermined maximum size while the timer is running, stopping the timer once the formation of the cluster is completed, and transmitting the cluster of IP packets to a lower layer of the UE, where the lower layer treats the cluster of IP packets as a single payload to minimize the IP packets handled at the lower layer of the UE.

A data structure is generated to store information about a set of writers associated with a copy service. The information is gathered from the copy service and populated into the data structure. The information includes names of the writers, writer types as being system or application writers, and system writer subtypes as being one of bare metal recovery (BMR) writers or system state recovery (SSR) writers. The data structure is reviewed to determine whether a particular writer should participate in the backup. Based on the review, a list is generated including a subset of the participating writers. Instructions are issued, via the copy service, for the writers in the list to prepare for creation of a snapshot. Upon creation of the snapshot, data is backed up from the snapshot to secondary storage.

Dynamic backup and discovery of new writers of a copy service

A production host includes a persistent storage and a backup manager. The persistent storage stores virtual machine data and a service group list associated with an application service group. The backup manager obtains a backup generation request for the application service group that includes virtual machines, and each of the virtual machines uses a copy of the virtual machine data; in response to obtaining the backup generation request: identifies a first virtual machine the virtual machines that is prioritized for generating a backup for the application service group based on the service group list; attempts to generate the backup using the first virtual machine and the copy of the virtual machine data; and stores the backup in backup storage.

System and method for selection of node for backup in distributed system

A backup storage includes a persistent storage and a backup manager. The persistent storage stores backups of entities and a global application data map. The backup manager obtains a restoration request for restoration of an application hosted by an entity of the entities; makes a determination to accelerate the restoration based, at least in part, on the application; in response to the determination: identifies a virtual disk level backup of the entity that is associated with the application using the global application data map; obtains the virtual disk level backup from the backups of the entities; and restores the application using the virtual disk level backup.

System and method for accelerated data access

A method for providing an application service to clients includes identifying a failure of the application service that causes the application service to be suspended; in response to identifying the failure: instantiating an instance of an application for providing the application service in a production host; identifying at least one virtual disk level backup that is: associated with the application and is a portion of deduplicated backups; extracting the at least one virtual disk level backup from deduplicated backups to obtain a copy of the at least one virtual disk level backup; identifying application data associated with the application within the copy of the at least one virtual disk level backup; transitioning an application service session for a client of the clients to the instance of the application; and resuming the application service for the client using the instance of the application and the application data.

System and method for accelerating application service restoration

A backup storage includes persistent storage and a backup manager. The persistent storage stores backups of entities and an entity list that lists the entities. The backup manager obtains a restoration availability request from a user; filters the entity list based on an identity of the user to obtain an available entity list; identifies, based on user input obtain based on the available entity list, an entity of the entities; and restores the entity using the backups.

System and method for limiting restoration access

A method for managing backups that includes generating a full backup of a database and, after generating the full backup, generating N incremental backups of the database and generating a first differential backup of the database after the N incremental backups have been generated, wherein the first differential backup is generated relative to the full backup.

Method and system for automation of differential backups

A backup storage includes a persistent storage and a backup manager. The persistent storage stores virtual machine level backups and application level backups. The backup manager obtains a request for a point in time restoration of an application; identifies, based on the application, a virtual machine level backup of the virtual machine level backups that is associated with: a virtual machine that hosted an instance of the application and a first point in time prior to a restoration point in time specified by the request for the point in time restoration; identifies, based on the application, an application level backup of the application level backups that is associated with the restoration point in time; generates a point in time backup using: the identified virtual machine level backup, and the identified application level backup; and services the request using the point in time backup.
