Abstract

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.

Description

Background technique [0001] A computing device may generate data during its operation. For example, an application program hosted by a computing device may generate data that is used by the application program to perform its functions. Such data may be stored in persistent storage of the computing device. Failure of persistent storage may result in data loss. [0002] To prevent data loss, copies of data can be stored in multiple locations. For example, a copy of data from a first computing may be stored in a second computing device. Depending on the size of the data, the computational cost to maintain a copy of the data and to provide a copy of the data to account for a failure of the first computing device may be high. Contents of the invention [0003] In one aspect, a backup storage device according to one or more embodiments of the invention includes a persistent storage device and a backup manager. Persistent storage stores the entity's backup and global applicati...
