Techniques to back up data are disclosed. In various embodiments, a function pointer associated with a system call by an application is modified to point to a custom write function. A request to write application data is received at the custom write function. The application data is written to a backup destination based at least in part on a determination that the request is associated with invocation of a backup method of the application.

Modifying function pointers to back up application data

A system for providing data protection services for data generated by host components hosted by hosts includes persistent storage for storing data and a local data protection manager. The local data protection manager identifies a data protection trigger event associated with a host component hosted by the host, identifies an add-on library associated with the host component, identifies a data protection agent associated with the host component, and initiates performance of data protection services by the data protection agent using the add-on library.

Method and system for performing data protection management using an add-on application programming interface

Systems and methods for backing up and restoring virtual machines in a cluster environment. An instrumentation interface enables configuration data to be stored with save sets during backup and enables the configuration of the destination to be adjusted based on the stored configuration during a restore.

Virtual backup and restore of virtual machines

Systems and methods for backing up data and for restoring at least sub-sets of the backed up data or for restoring sub-sets of data from a single file. An offset map is generated when backing up data. The offset map identifies at least starting locations of files and data records in the backup. A request for specific data is accommodated by identified the start locations of the specific data and then extracting the requested data from the backup. The requested data can then be restored independently of the entire backup.

File block addressing for backups

An agent for managing backup generation for virtual machines includes a persistent storage stores backup policies and a backup manager that obtains request for generating a backup for a first virtual machine of the virtual machines and, in response to obtaining the request, generates a backup load prediction for generating the backup; performs a resource availability analysis of a host computing device hosting the first virtual machine to determine computing resources availability for generating the backup; makes a first determination, using the backup load prediction and the computing resource availability, that the host computing device has insufficient resources for generating the backup; and, in response to the first determination, performs a backup type analysis on existing backups associated with the first virtual machine to obtain at least one updated backup policy; and generates a reduced-resource cost backup for the virtual machine using at least one of the updated backup policies.

System and method for dynamic configuration of backup agents

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 managing backups includes obtaining a plurality of parameters for a data item, filtering the plurality of parameters to obtain a plurality of filtered parameters, evaluating each filtered parameter of the plurality of filtered parameters to obtain a plurality of evaluated parameters, updating a promotion parameter register based on the plurality of evaluated parameters, and processing a backup request using the promotion parameter register, wherein the backup request specifies the data item.

System and method for selective backup promotion using a dynamically reserved memory register

An agent for managing virtual machines includes a persistent storage and an application agent manager. The persistent storage stores backup policies. The application agent manager identifies a new virtual machine instance and, in response to identifying the new virtual machine instance, performs proxy agent based analysis of the new virtual machine instance to generate a data loss threat profile of the new virtual machine instance; remediates the new virtual machine instance by instantiating application agents for the new virtual machine instance based on the data loss threat profile and a portion of the backup policies associated with the new virtual machine instance; updates at least one of the backup policies based on the instantiated application agents; and performs an application backup session for the new virtual machine instance using the instantiated application agents.

System and method for orchestrated backup in a virtualized environment

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

Systems and methods for backing up and restoring virtual machines in a cluster environment. Proxy nodes in the cluster are configured with agents. The agents are configured to perform backup operations and restore operations for virtual machines operating in the cluster. During a backup operation or during a restore operation, a load associated with the backup/restore operation is distributed across at least some of the proxy nodes. The proxy nodes can backup/restore virtual machines on any of the nodes in the cluster.

Optimized backup of clusters with multiple proxy servers

Image restore from incremental backup

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.

System and method for accelerated point in time restoration

Systems and methods for backing up and restoring virtual machines in a cluster environment. A cluster agent that is cluster aware operates as an interface with the backup server. The cluster agent can locate the virtual machines being backed up or restored and coordinate with a local agent to perform the backup or restore of the virtual machines.

Highly available cluster agent for backup and restore operations

Systems and methods for granularly recovering a backup are provided. An image of a backup is mounted as a file system such that the files can be granularly restored. Image-level recovery and file-level recovery can be achieved from the same backup. The backup may also be de-duplicated.

De-duplicated file share mounting for granular level data recoveries
