System and method for efficient restore
View Patent ↗An agent for managing virtual machines includes a persistent storage and a processor. The persistent storage stores backup/restoration policies. The processor identifies a virtual machine of the virtual machines that is likely to fail and, in response to identifying the virtual machine, identifies backup data associated with the identified virtual machine; instantiates a clone of the identified virtual machine using the identified backup; exposes the clone while the identified virtual machine is exposed; and hides the virtual machine after the clone is exposed.
1. An agent for managing virtual machines, comprising:
a persistent storage that stores backup/restoration policies; and
a processor programmed to:
identify a virtual machine of the virtual machines that is likely to fail;
in response to identifying the virtual machine:
identify backup data associated with the identified virtual machine;
instantiate a clone of the identified virtual machine using the identified backup;
expose the clone while the identified virtual machine is exposed; and
hide the virtual machine after the clone is exposed;
before instantiating the clone:
make a determination that the backup data is not clone-ready based on configuration data of the backup data; and
in response to the determination:
perform a collision analysis to obtain collision free configuration data, and
modify the configuration data based on the collision free configuration data.
2. The agent of claim 1 , wherein the clone and the identified virtual machine comprise same application data.
3. The agent of claim 1 , wherein the clone and the identified virtual machine comprise different configuration data.
4. The agent of claim 3 , wherein the configuration data of the identified virtual machine comprises a first uniform resource identifier, the configuration data of the clone comprises a second uniform resource identifier, and the first uniform resource identifier is different from the second uniform resource identifier.
5. The agent of claim 3 , wherein the configuration data of the identified virtual machine comprises a first media access control address, the configuration data of the clone comprises a second media access control address, and the first media access control address is different from the second media access control address.
6. The agent of claim 3 , wherein the configuration data of the identified virtual machine comprises a first internet protocol address, the configuration data of the clone comprises a second internet protocol address, and the first internet protocol address is different from the second internet protocol address.
7. The agent of claim 1 , wherein identifying the virtual machine of the virtual machines that is likely to fail comprises:
filtering the virtual machines using the backup/restoration policies to identify a provisional set of virtual machines that are failing, wherein the backup/restoration policies indicate that a backup failure has occurred during each virtual machine's most recently scheduled backup session;
for each virtual machine of the provisional set, determining a responsiveness of the respective virtual machines to backup generation session requests;
obtaining a final set of failing virtual machines by filtering the provisional set for all non-responsive virtual machines using the determined responsiveness; and
selecting any virtual machine of the final set of failing virtual machines as the identified virtual machine that is likely to fail.
8. The agent of claim 1 , wherein instantiating the clone of the identified virtual machine using the identified backup comprises:
identifying a restoration policy associated with the identified virtual machine;
instantiating a new virtual machine at a location specified by the identified restoration policy using the identified backup data; and
migrating the instantiated new virtual machine to a second location specified by the identified backup data.
9. The agent of claim 8 , wherein the location is a proxy host.
10. The agent of claim 8 , wherein the second location is a production host.
11. The agent of claim 8 , wherein the identified virtual machine is at the second location.
12. The agent of claim 1 , wherein exposing the clone commences execution of the clone.
13. The agent of claim 1 , wherein hiding the identified virtual machine suspends execution of the identified virtual machine.
14. The agent of claim 1 , wherein the processor is further programmed to:
after exposing the clone:
update the backup/restoration policies based on configuration data of the clone,
wherein the configuration data comprises an identifier selected from a group of identifiers consisting of a uniform resource identifier, a media access control address, and an internet protocol address.
15. The agent of claim 14 , wherein updating the backup/restoration policies based on configuration information of the clone comprises:
identifying a backup policy associated with the identified virtual machine; and
updating a target identifier of the backup policy to reflect the configuration data.
16. A method for managing virtual machines, comprising:
identifying a virtual machine of the virtual machines that is likely to fail;
in response to identifying the virtual machine:
identifying backup data associated with the identified virtual machine;
instantiating a clone of the identified virtual machine using the identified backup;
exposing the clone while the identified virtual machine is exposed; and
hiding the virtual machine after the clone is exposed;
before instantiating the clone:
making a determination that the backup data is not clone-ready based on configuration data of the backup data; and
in response to the determination:
performing a collision analysis to obtain collision free configuration data, and
modifying the configuration data based on the collision free configuration data.
17. The method of claim 16 , wherein instantiating a clone of the identified virtual machine using the identified backup comprises:
identifying a restoration policy associated with the identified virtual machine;
instantiating a new virtual machine at a location specified by the identified restoration policy using the identified backup data; and
migrating the instantiated new virtual machine to a second location specified by the identified backup data.
18. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing virtual machines, the method comprising:
identifying a virtual machine of the virtual machines that is likely to fail;
in response to identifying the virtual machine:
identifying backup data associated with the identified virtual machine;
instantiating a clone of the identified virtual machine using the identified backup;
exposing the clone while the identified virtual machine is exposed;
hiding the virtual machine after the clone is exposed;
before instantiating the clone:
making a determination that the backup data is not clone-ready based on configuration data of the backup data; and
in response to the determination:
performing a collision analysis to obtain collision free configuration data, and
modify the configuration data based on the collision free configuration data.
19. The non-transitory computer readable medium of claim 18 , wherein instantiating a clone of the identified virtual machine using the identified backup comprises:
identifying a restoration policy associated with the identified virtual machine;
instantiating a new virtual machine at a location specified by the identified restoration policy using the identified backup data; and
migrating the instantiated new virtual machine to a second location specified by the identified backup data.
