Abstract: Aspects of the disclosure accelerate recovery using a combination of local and remote backups. A backup selector identifies a latest unencrypted remote backup (e.g., created prior to an encrypted backup), a latest unencrypted local backup created prior to the latest unencrypted remote backup, and a penultimate unencrypted remote backup created prior to the latest unencrypted local backup. A restoration manager restores a local computing asset to the state of the latest unencrypted local backup. In a disaster recovery (DR) environment, two differences are generated: one between the latest unencrypted remote backup and the penultimate unencrypted remote backup and another between a newly-generated failback backup and the latest unencrypted remote backup. The two differences are sent to the restoration manager to roll the state of the local computing asset forward in two stages. This approach is faster and reduces egress charges in cloud-based DR environments.
