APPLICATION SNAPSHOT FOR HIGHLY AVAILABLE AND DISTRIBUTED VOLUMES

A single application may rely on data storage provided by a plurality of virtual data storage volumes mounted on one or more compute nodes. A crash-consistent snapshot of the state of the application may be generated. Each of the virtual data storage volumes may be quiesced prior to the capture of a...

Zusammenfassung:A single application may rely on data storage provided by a plurality of virtual data storage volumes mounted on one or more compute nodes. A crash-consistent snapshot of the state of the application may be generated. Each of the virtual data storage volumes may be quiesced prior to the capture of a plurality of volume-level snapshots, after which each volume is unquiesced. The crash-consistent snapshot may be used to restore the application to the state at the time the snapshot was captured.
