In-place data recovery
An in-place data recovery method and system include receiving a user request to restore a virtual machine to a version corresponding to a first point in time, identifying a first snapshot of the virtual machine based on the user request, generating a second snapshot of the virtual machine, identifying a second data block in the second snapshot that includes modified data derived from data content of a first data block in the first snapshot, generating reverse incremental backup data including the first data block, and restoring the virtual machine in-place based on the reverse incremental backup data.

restoring the virtual machine in-place while the virtual machine is disconnected from the virtual power source or the network of the primary storage platform.
6. The method of claim 1 , further comprising:
upon restoring the virtual machine in-place, removing the second snapshot from a storage appliance associated with the virtual machine in absence of a user request to keep the second snapshot.
7. The method of claim 1 , wherein the plurality of configuration properties at least includes a number of CPUs, a size of memory, and a number of disks of the virtual machine.
8. The method of claim 1 , wherein identifying the first snapshot of the virtual machine based on the user request further comprises:
identifying the first snapshot based on an associated search index being included in the user request.
9. The method of claim 1 , wherein the first snapshot is a full snapshot or an incremental snapshot.
10. A system, comprising:
a memory storing instructions; and
one or more processors communicatively coupled to the memory and configured by the instructions to perform operations comprising:
receiving a user request to restore a virtual machine to a version corresponding to a first point in time, the virtual machine associated with a plurality of configuration properties;
identifying a first snapshot of the virtual machine based on the user request;
generating a second snapshot of the virtual machine, the second snapshot corresponding to a second point in time subsequent to the user request;
identifying a second data block in the second snapshot that includes modified data derived from data content of a first data block in the first snapshot;
generating reverse incremental backup data including the first data block; and
restoring the virtual machine in-place based on the reverse incremental backup data, a restored virtual machine associated with the plurality of configuration properties.
11. The system of claim 10 , the one or more processors configured by the instructions to perform operations further comprising:
identifying a block offset associated with the second data block in a disk of the virtual machine; and
overwriting the second data block in the disk with the data content of the first data block based on the block offset.
12. The system of claim 10 , the one or more processors configured by the instructions to perform operations further comprising:
in response to receiving the user request, disconnecting the virtual machine from a virtual power source or a network of a primary storage platform hosting the virtual machine prior to generating the second snapshot.
13. The system of claim 12 , the one or more processors configured by the instructions to perform operations further comprising:
reconnecting the virtual machine to the virtual power source or the network of the primary storage platform upon restoring the virtual machine in-place based on the reverse incremental backup data.
14. The system of claim 12 , the one or more processors configured by the instructions to perform operations further comprising:
restoring the virtual machine in-place while the virtual machine is disconnected from the virtual power source or the network of the primary storage platform.
15. The system of claim 10 , the one or more processors configured by the instructions to perform operations further comprising:
upon restoring the virtual machine in-place, removing the second snapshot from a storage appliance associated with the virtual machine in absence of a user request to keep the second snapshot.
16. The system of claim 10 , wherein the plurality of configuration properties at least includes a number of CPUs, a size of memory, and a number of disks of the virtual machine.
17. The system of claim 10 , wherein to identify the first snapshot of the virtual machine based on the user request, the one or more processors are configured by the instructions to perform operations further comprising:
identifying the first snapshot based on an associated search index being included in the user request.
18. The system of claim 10 , wherein the first snapshot is a full snapshot or an incremental snapshot.
19. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
receiving a user request to restore a virtual machine to a version corresponding to a first point in time, the virtual machine associated with a plurality of configuration properties;
identifying a first snapshot of the virtual machine based on the user request;
generating a second snapshot of the virtual machine, the second snapshot corresponding to a second point in time subsequent to the user request;
