CLOUD-BASED DATABASE BACKUP AND RECOVERY

A system for database backup including a controller, a metadata database coupled to the controller, a backup tool coupled to the controller, and a plurality of nodes coupled to the backup tool and accessed through a file system. The controller is configured to determine a first data change in node; in response to determining the first data change, freeze the file system; and generate an incremental snapshot of the at least one of the plurality of nodes (where the incremental snapshot including a portion of the at least one of the plurality of nodes). The controller is also configured to upload an encrypted copy of the incremental snapshot to a cloud storage; update the metadata database by storing an entry associating the incremental snapshot with the at least one of the plurality of nodes and unfreezing the file system.
