Abstract: Systems, methods, and computer readable media for preventing data loss at ephemeral and/or volatile storage of a local storage system are provided. These techniques may include synchronizing that state of the ephemeral storage system to a cloud-based storage system and capturing a cloud snapshot of the cloud-based storage system. In the event of a failure at the volatile storage, the cloud-based snapshot can be used as a restore point for the cloud-based storage system, the state of which can then be synchronized back to the volatile storage. Additionally, the local storage system includes durable storage for storing transaction logs. After synchronizing the state of the cloud-based storage system to the volatile storage, the local storage system can playback transactions in the transaction log to restore the volatile segment to the state at the time of the failure.

Abstract: Systems, methods, and computer readable media for snapshotting ephemeral and/or volatile storage systems are provided. These techniques may include synchronizing that state of the ephemeral storage system to a cloud-based storage system and capturing a cloud snapshot of the cloud-based storage system. To reduce the time to capture a cloud snapshot, techniques disclosed herein include obtaining sets of pending data changes to the ephemeral storage system that have not been synchronized to the cloud-based storage system. When the pending data changes satisfy a threshold metric, the pending data changes may then be synchronized to the ephemeral storage system on a rolling basis.
