Techniques for managing non-snappable volumes
Techniques for managing non-snappable volumes are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for managing non-snappable volumes comprising identifying a virtual disk associated with a virtual machine, identifying a non-snappable volume associated with the virtual disk, analyzing the non-snappable volume, using at least one computer processor, to determine whether the non-snappable volume contains application data, and performing one or more responsive actions in the event the non-snappable volume is determined to contain application data.
1. A method for managing non-snappable volumes comprising:
detecting a backup process of a virtual machine;
identifying a virtual disk associated with the virtual machine when the backup process is detected;
determining whether a non-snappable volume is associated with the virtual disk;
mapping information associated with the virtual disk into mount point information to allow analysis of the non-snappable volume and obtaining metadata about content of the non-snappable volume when it is determined that the non-snappable volume is associated with the virtual disk;
analyzing the non-snappable volume via the mapped information and metadata, using at least one computer processor, to determine whether the non-snappable volume contains application data, wherein determining whether the non-snappable volume contains application data comprises:
identifying one or more files associated with an application of the virtual machine; and
determining whether at least one of the one or more files are present on the non-snappable volume;
performing one or more responsive actions in the event the non-snappable volume is determined to contain application data, wherein performing one or more responsive actions in the event the non-snappable volume is determined to contain application data comprises providing a notification to a user during initiation or configuration of a backup that the non-snappable volume will not be backed up, and wherein the user notification provides a warning to the user through a user interface; and
ignoring the non-snappable volume in the event the non-snappable volume is determined not to contain application data.
2. The method of claim 1 , wherein identifying the virtual disk associated with the virtual machine comprises querying a hypervisor.
3. The method of claim 1 , wherein the non-snappable volume comprises an independent mode virtual disk.
4. The method of claim 1 , wherein the non-snappable volume comprises a Raw Device Mapping (RDM).
5. The method of claim 1 , wherein analyzing the non-snappable volume to determine whether the non-snappable volume contains application data is performed by a backup agent on the virtual machine.
6. The method of claim 5 , wherein the backup agent is an application specific backup agent.
7. The method of claim 1 , wherein performing one or more responsive actions in the event the non-snappable volume is determined to contain application data comprises adding the non-snappable volume to the backup process.
8. The method of claim 1 , wherein identifying a non-snappable volume associated with the virtual disk comprises querying a backup client on a virtual machine.
9. The method of claim 1 , wherein analyzing the non-snappable volume to determine whether the non-snappable volume contains application data is performed by a backup server.
10. The method of claim 1 , wherein the application data comprises one or more database files.
11. At least one non-transitory processor readable storage medium for storing a computer program of instructions configured to be readable by at least one processor for instructing the at least one processor to execute a computer process for performing the method as recited in claim 1 .
12. The method of claim 1 , wherein the user notification comprises an email.
13. An article of manufacture for managing non-snappable volumes, the article of manufacture comprising:
at least one non-transitory processor readable storage medium; and
instructions stored on the at least one storage medium;
wherein the instructions are configured to be readable from the at least one storage medium by at least one processor and thereby cause the at least one processor to operate so as to:
detect a backup process of a virtual machine;
identify a virtual disk associated with the virtual machine when the backup process is detected;
determine whether a non-snappable volume is associated with the virtual disk;
map information associated with the virtual disk into mount point information to allow analysis of the non-snappable volume and obtain metadata about content of the non-snappable volume when it is determined that the non-snappable volume is associated with the virtual disk;
analyze the non-snappable volume via the mapped information to determine whether the non-snappable volume contains application data, wherein determining whether the non-snappable volume contains application data comprises:
identifying one or more files associated with an application of the virtual machine; and
determining whether at least one of the one or more files are present on the non-snappable volume;
performing one or more responsive actions in the event the non-snappable volume is determined to contain application data, wherein performing one or more responsive actions in the event the non-snappable volume is determined to contain application data comprises providing a notification to a user during initiation or configuration of a backup that the non-snappable volume will not be backed up, and wherein the user notification provides a warning to the user through a user interface; and
ignoring the non-snappable volume in the event the non-snappable volume is determined not to contain application data.
14. A system for managing non-snappable volumes comprising:
one or more processors communicatively coupled to a network, wherein the one or more processors are configured to:
detect a backup process of a virtual machine;
identify a virtual disk associated with the virtual machine when the backup process is detected;
determine whether a non-snappable volume is associated with the virtual disk;
map information associated with the virtual disk into mount point information to allow analysis of the non-snappable volume and obtaining metadata about content of the non-snappable volume when it is determined that the non-snappable volume is associated with the virtual disk;
analyze the non-snappable volume via the mapped information to determine whether the non-snappable volume contains application data, wherein determining whether the non-snappable volume contains application data comprises:
identifying one or more files associated with an application of the virtual machine; and
determining whether at least one of the one or more files are present on the non-snappable volume;
performing one or more responsive actions in the event the non-snappable volume is determined to contain application data, wherein performing one or more responsive actions in the event the non-snappable volume is determined to contain application data comprises providing a notification to a user during initiation or configuration of a backup that the non-snappable volume will not be backed up, and wherein the user notification provides a warning to the user through a user interface; and
ignoring the non-snappable volume in the event the non-snappable volume is determined not to contain application data.
15. The system of claim 14 , wherein the non-snappable volume comprises an independent mode virtual disk.
16. The system of claim 14 , wherein the non-snappable volume comprises a Raw Device Mapping (RDM).
17. The system of claim 14 , wherein analyzing the non-snappable volume to determine whether the non-snappable volume contains application data is performed by a backup agent on the virtual machine.
