In-Place cloud instance restore
The disclosed technology teaches recovering a first virtual machine or an instance with an Internet Protocol address, a first root volume and one or more data volumes that are corrupted. The first virtual machine is hosted by a first cloud server that hosts plurality of virtual machines. The disclosed technology includes instructing the first cloud server to launch a recovery virtual machine. The recovery virtual machine launches one or more new data volumes based upon captured file system images in one or more snapshots taken of corrupted data volumes of the first virtual machine prior to becoming corrupted. The recovery virtual machine detaches the corrupted data volumes and attaches the new data volumes launched to the first virtual machine. The Internet Protocol address of the first virtual machine remains unchanged.
1 . A method, comprising:
receiving, at a workload management system, a virtual machine recovery instruction, wherein a first cloud server of a hosted service environment hosts one or more virtual machines associated with the workload management system;
instructing the first cloud server to launch a recovery instance in the hosted service environment;
instructing the recovery instance to mount one or more data volumes corresponding to a first snapshot stored in the hosted service environment, the first snapshot capturing a machine state at a point in time;
replacing a first root volume associated with the recovery instance with a second root volume;
instructing the recovery instance to detach the one or more data volumes;
attaching the one or more data volumes to a first virtual machine; and
starting the first virtual machine including the second root volume and the one or more data volumes.
2 . The method of claim 1 , wherein the first virtual machine has an address and the address remains unchanged.
3 . The method of claim 2 , wherein the address is an IP address.
4 . The method of claim 1 , wherein the second root volume contains an operating system.
5 . The method of claim 4 , wherein the second root volume is created from an operating system image.
6 . The method of claim 4 , wherein the second root volume is created by mounting a snapshot containing an image of a previous version of a root volume of the first virtual machine.
7 . The method of claim 1 , wherein the workload management system is hosted by the first cloud server of the hosted service environment.
8 . A system, comprising:
one or more memories; and
one or more processors, wherein the one or more memories store code comprising instructions executable by the one or more processors to cause the system to perform actions comprising:
receiving, at a workload management system, a virtual machine recovery instruction, wherein a first cloud server of a hosted service environment hosts one or more virtual machines associated with the workload management system;
instructing the first cloud server to launch a recovery instance in the hosted service environment;
instructing the recovery instance to mount one or more data volumes corresponding to a first snapshot stored in the hosted service environment, the first snapshot capturing a machine state at a point in time;
replacing a first root volume associated with the recovery instance with a second root volume;
instructing the recovery instance to detach the one or more data volumes;
attaching the one or more data volumes to a first virtual machine; and
starting the first virtual machine including the second root volume and the one or more data volumes.
9 . The system of claim 8 , wherein the first virtual machine has an address and the address remains unchanged.
10 . The system of claim 9 , wherein the address is an IP address.
11 . The system of claim 8 , wherein the second root volume contains an operating system.
12 . The system of claim 11 , wherein the instructions are further executable by the one or more processors to cause the system to create the second root volume from an operating system image.
13 . The system of claim 11 , wherein the instructions are further executable by the one or more processors to cause the system to create the second root volume by mounting a snapshot containing an image of a previous version of a root volume of the first virtual machine.
14 . The system of claim 8 , wherein the workload management system is hosted by the first cloud server of the hosted service environment.
15 . A non-transitory computer readable medium storing instructions, the instructions configured to, when executed by one or more processors, cause the one or more processors to perform actions comprising:
receiving, at a workload management system, a virtual machine recovery instruction, wherein a first cloud server of a hosted service environment hosts one or more virtual machines associated with the workload management system;
instructing the first cloud server to launch a recovery instance in the hosted service environment;
instructing the recovery instance to mount one or more data volumes corresponding to a first snapshot stored in the hosted service environment, the first snapshot capturing a machine state at a point in time;
replacing a first root volume associated with the recovery instance with a second root volume;
instructing the recovery instance to detach the one or more data volumes;
attaching the one or more data volumes to a first virtual machine; and
starting the first virtual machine including the second root volume and the one or more data volumes.
16 . The non-transitory computer readable medium of claim 15 , wherein the first virtual machine has an address and the address remains unchanged.
17 . The non-transitory computer readable medium of claim 16 , wherein the address is an IP address.
18 . The non-transitory computer readable medium of claim 15 , wherein the second root volume contains an operating system.
19 . The non-transitory computer readable medium of claim 18 , wherein the instructions are further configured to, when executed by one or more processors, cause the one or more processors to create the second root volume from an operating system image.
20 . The non-transitory computer readable medium of claim 18 , wherein the instructions are further configured to, when executed by one or more processors, cause the one or more processors to create the second root volume by mounting a snapshot containing an image of a previous version of a root volume of the first virtual machine.
