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.
1. A method, comprising:
receiving a 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 request;
generating a second snapshot of the virtual machine, the second snapshot corresponding to a second point in time subsequent to the 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; and
restoring the virtual machine in-place based on identifying the second data block in the second snapshot that includes modified data derived from data content of the first data block in the first snapshot.
2. The method of claim 1 , wherein restoring the virtual machine in-place further comprises:
overwriting the second data block in a disk of the virtual machine with the data content of the first data block.
3. The method of claim 2 , wherein restoring the virtual machine in-place further comprises:
identifying a block offset associated with the second data block in the disk of the virtual machine, wherein overwriting the second data block in the disk with the data content of the first data block is based on the block offset.
4. The method of claim 1 , further comprising:
in response to receiving the 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.
5. The method of claim 4 , 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.
6. The method of claim 4 , 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.
7. 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 second request to keep the second snapshot.
8. The method of claim 1 , wherein the virtual machine is associated with a plurality of configuration properties comprising a number of CPUs, a size of memory, and a number of disks of the virtual machine, and wherein the restored virtual machine is associated with the plurality of configuration properties.
9. The method of claim 1 , wherein identifying the first snapshot of the virtual machine based on the request further comprises:
identifying the first snapshot based on an associated search index being included in the request.
10. The method of claim 1 , wherein the first snapshot is a full snapshot or an incremental snapshot.
11. 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 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 request;
generating a second snapshot of the virtual machine, the second snapshot corresponding to a second point in time subsequent to the 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; and
restoring the virtual machine in-place based on identifying the second data block in the second snapshot that includes modified data derived from data content of the first data block in the first snapshot.
12. The system of claim 11 , the one or more processors configured by the instructions to perform operations further comprising:
overwriting the second data block in a disk of the virtual machine with the data content of the first data block.
13. The system of claim 12 , 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 the disk of the virtual machine, wherein overwriting the second data block in the disk with the data content of the first data block is based on the block offset.
14. The system of claim 11 , the one or more processors configured by the instructions to perform operations further comprising:
in response to receiving the 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.
15. The system of claim 14 , 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.
16. The system of claim 14 , 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.
17. The system of claim 11 , 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 second request to keep the second snapshot.
18. The system of claim 11 , wherein the virtual machine is associated with a plurality of configuration properties comprising a number of CPUs, a size of memory, and a number of disks of the virtual machine, and wherein the restored virtual machine is associated with the plurality of configuration properties.
19. The system of claim 11 , the one or more processors configured by the instructions to perform operations further comprising:
identifying the first snapshot based on an associated search index being included in the request.
20. 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 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 request;
generating a second snapshot of the virtual machine, the second snapshot corresponding to a second point in time subsequent to the 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; and
restoring the virtual machine in-place based on identifying the second data block in the second snapshot that includes modified data derived from data content of the first data block in the first snapshot.
