Abstract
On-the-fly point-in-time recovery operations are disclosed. During a recovery operation, the PiT being restored can be changed on-the-fly or during the existing recovery operation without restarting the recovery process from the beginning. IN one example, this improves recovery time operation (RTO) and prevents aspects of the recovery operation to be avoided when changing to a different PiT.
Claims20
A method, comprising:
- selecting a point-in-time (PiT) to recover from a plurality of PiTs;
- converting an image of a virtual machine in the selected PiT to a converted virtual machine;
- attaching a hydrated operating system (OS) disk to the converted virtual machine;
- hydrating a data disk from the PiT as a volume and attaching the volume to the converted virtual machine;
- taking a snapshot of the volume;
- operating the converted virtual machine as a restored virtual machine and running an application on the restored virtual machine;
- and
- moving the volume to a second PiT included in the plurality of PiTs when the volume attached to the restored virtual machine is not validated without requiring a second conversion of a second image of a virtual machine.

A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising:
- selecting a point-in-time (PiT) to recover from a plurality of PiTs;
- converting an image of a virtual machine in the selected PiT to a converted virtual machine;
- attaching a hydrated operating system (OS) disk to the converted virtual machine;
- hydrating a data disk from the PiT as a volume and attaching the volume to the converted virtual machine;
- taking a snapshot of the volume;
- operating the converted virtual machine as a restored virtual machine and running an application on the restored virtual machine;
- and
- moving the volume to a second PiT included in the plurality of PiTs when the volume attached to the restored virtual machine is not validated without requiring a second conversion of a second image of a virtual machine.
