Application protection through a combined functionality failure manager
A method for providing application functionality protection. The method includes accessing a distributed computer system having a cluster including a plurality of nodes, and receiving an indication of an application failure. The method further includes attempting to restore the application through a number of application restart attempts, and receiving an indication that the restart attempts have not restored the application. An image history is then accessed to obtain a last known good point in time image of the application. The application is restored in accordance with the last known good point in time image.
1. A method for providing application functionality protection by integrated control of cluster failover processes and cluster backup processes, comprising:
accessing a distributed computer system having a cluster including a plurality of nodes;
receiving, at a failure manager having combined access to failover functionality and backup functionality, an indication of an application failure on a first node;
attempting, by the failure manager, to restore the application through a preconfigured number of application restart attempts;
determining, by the failure manager, that application restart attempts have failed;
selecting, by the failure manager, in response to the determination, at least one secondary restart attempt to perform based on a configured policy;
performing the at least one secondary restart attempt to restore application functionality comprising at least one of:
restarting a machine hosting the application; and
failing over to a second node;
receiving, by the failure manager, an indication that the at least one secondary restart attempt has not restored the application;
accessing, by the failure manager, a backup image history to obtain a last known good point in time backup image of the application, wherein the backup image history includes at least two prior backup images; and
restoring, by the failure manger, the application in accordance with the last known good point in time backup image, wherein the application is restored using a standby virtual machine provisioned from the last known good point in time backup image.
2. The method of claim 1 , wherein the backup image history comprises a plurality of point in time snapshots.
3. The method of claim 1 , wherein a user indication is required to proceed with restoration with the last known good point in time backup image.
4. The method of claim 1 , wherein the distributed computer system comprises a plurality of clusters of nodes.
5. A non-transitory computer readable storage medium having stored thereon, computer executable instructions that, if executed by a computer system cause the computer system to perform a method for providing application functionality protection by integrated control of cluster failover processes and cluster backup processes, comprising:
accessing, by the failure manager, a distributed computer system having a cluster including a plurality of nodes;
receiving, by the failure manager, an indication of an application failure on a first of the plurality of nodes at a failure manager having combined access to failover functionality and backup functionality;
attempting, by the failure manager, to restore the application through a preconfigured number of application restart attempts;
determining, by the failure manager, that the application restart attempts have failed;
selecting, by the failure manager, in response to the determination, the at least one secondary restart attempt to perform based on a configured policy;
performing at least one secondary restart attempt to restore application functionality comprising at least one of:
restarting a machine hosting the application; and
failing over to a second node;
receiving, by the failure manager, an indication that the at least one secondary restart attempt has not restored the application;
accessing, by the failure manager, a backup image history to obtain a last known good point in time backup image of the application, wherein the backup image history includes at least two prior backup images; and
restoring, by the failure manager, the application in accordance with the last known good point in time backup image, wherein the application is restored using a standby virtual machine provisioned from the last known good point in time backup image.
6. The computer readable storage medium of claim 5 , wherein the restart attempts include at least one restart of the node machine.
7. The computer readable storage medium of claim 5 , wherein the backup “image history comprises a plurality of point in time snapshots.
8. The computer readable storage medium of claim 5 , wherein a user indication is required to proceed with restoration with the last known good point in time backup image.
9. The computer readable storage medium of claim 5 , wherein the distributed computer system comprises a plurality of clusters of nodes.
10. A server computer system, comprising:
a computer system having a processor coupled to a computer readable storage media and executing computer readable code which causes the computer system to implement a failure manager having combined access to failover functionality and backup functionality to integrate control of cluster failover and cluster backup by:
accessing, by the failure manager, a distributed computer system having a cluster including a plurality of nodes;
receiving, by the failure manager, an indication of an application failure on a first node;
attempting, by the failure manager, to restore the application through a number of application restart attempts;
determining, by the failure manager, that application restart attempts have failed;
selecting by the failure manager, in response to the determination, the at least one secondary restart attempt to perform based on a configured policy;
performing at least one secondary restart attempt to restore application functionality comprising at least one of:
restarting a machine hosting the application; and
failing over to a second node;
receiving, by the failure manager, an indication that the at least one secondary restart attempt has not restored the application;
accessing, by the failure manager, a backup image history to obtain a last known good point in time backup image of the application, wherein the backup image history includes at least two prior backup images; and
restoring, by the failure manager, the application in accordance with the last known good point in time backup image, wherein the application is restored using a standby virtual machine provisioned from the last known good point in time backup image.
11. The server computer system of claim 10 , wherein the backup image history comprises a plurality of point in time snapshots.
12. The server computer system of claim 10 , wherein a user indication is required to proceed with restoration with the last known good point in time backup image.
13. The server computer system of claim 10 , wherein restoring the application includes restoring a virtual machine to the last known good point in time backup image.
14. The method of claim 1 , further comprising:
determining that restoring the application in accordance with the last known good point in time backup image has failed and
restoring to a point in time of a backup image prior to the last known good point in time backup image.
