Abstract:
Methods and systems for reclaiming disk space via consolidation and deletion of expired snapshots are described. The expired snapshots may comprise snapshots of a virtual machine that are no longer required to be stored within a data storage domain (e.g., a cluster of data storage nodes or a cloud-based data store). In some cases, rather than storing an incremental file corresponding with a particular snapshot of the virtual machine, a full image of the particular snapshot may be generated and stored within the data storage domain. The generation of the full image may allow a chain of dependencies supporting the expired snapshots to be broken and for the expired snapshots to be deleted or consolidated. The full image of the particular snapshot may be generated using compute capacity in the cloud or may be generated locally by a storage appliance and uploaded to the data storage domain.

Claim (Index 1):
A method for operating a data management system, comprising:\n acquiring a first full image snapshot and a set of incremental files corresponding with different point in time versions of a virtual machine; storing the first full image snapshot and the set of incremental files; detecting that a data size for a first subset of the set of incremental files has exceeded a threshold data size; generating a second full image snapshot using the first full image snapshot and the first subset of the set of incremental files in response to detecting that the data size for the first subset of the set of incremental files has exceeded the threshold data size; and replacing a first incremental file of the first subset of the set of incremental files with the second full image snapshot.
