Application aware backup of virtual machines
Systems and methods for performing application aware backups and/or generating other application aware secondary copies of virtual machines are described. For example, the systems and methods described herein may access a virtual machine, automatically discover various databases and/or applications (e.g., SQL, Exchange, Sharepoint, Oracle, and so on) running on the virtual machine, and perform data storage operations that generate a backup, or other secondary copy, of the virtual machine, as well as backups, or other secondary copies, of each of the discovered applications.
1. A system for performing a data storage operation on a virtual machine, the system comprising:
a host computing device comprising one or more processors, computer memory, and a hypervisor, wherein the one or more processors is configured to:
for one or more applications hosted by a virtual machine, inject an application-specific data agent into the virtual machine that corresponds to the one or more applications hosted by the virtual machine,
wherein the application-specific data agent is configured to perform, at least, an application-specific backup job for a corresponding application that is executed in a specific virtual computing environment;
instruct each application-specific data agent injected into the virtual machine to perform an application-specific backup job,
wherein the application-specific backup job comprises creating a snapshot copy of the corresponding application; and,
create a backup copy of the virtual machine by associating each snapshot copy of the one or more applications with the backup copy of the virtual machine;
generate an index that comprises data imaged by snapshot copies of the one or more applications; and
map the generated index to an index of the backup copy of the virtual machine.
2. The system of claim 1 , wherein creating the backup copy of the virtual machine comprises performing a snapshot operation of the virtual machine to create a snapshot copy of the virtual machine, and wherein the snapshot copy of the virtual machine is a point-in-time copy that reflects locations of blocks of data stored in a data storage device.
3. The system of claim 1 , wherein creating the backup copy of the virtual machine comprises performing a streaming backup operation of the virtual machine to store a secondary copy of the virtual machine to magnetic tape storage media.
4. The system of claim 1 , wherein the one or more processors if further configured to: access a registry of the virtual machine to identify the one or more applications.
5. The system of claim 1 , the one or more processors if further configured to: quiesce an application into an application-consistent state prior to creating a snapshot copy of the corresponding application.
6. The system of claim 1 , wherein the one or more processors if further configured to: discover a SQL application, an Exchange application, an Oracle application, or a Sharepoint application.
7. A method for performing a data storage operation on a virtual machine, the method comprising:
for one or more applications hosted by a virtual machine, injecting a data agent into the virtual machine that corresponds to the one or more applications,
wherein the injected data agent is configured to perform, at least, an application-specific backup job for a corresponding application that is executed in a specific virtual computing environment;
instructing each application-specific data agent injected into the virtual machine to perform an application-specific backup job,
wherein the application-specific backup job comprises creating a snapshot copy of the corresponding application;
creating a backup copy of the virtual machine by associating each snapshot copy of each of the one or more applications with the backup copy of the virtual machine;
generating an index that comprises data imaged by snapshot copies of the one or more applications; and
mapping the generated index to an index of the backup copy of the virtual machine.
8. The method of claim 7 , wherein creating the backup copy of the virtual machine comprises performing a snapshot operation of the virtual machine to create a snapshot copy of the virtual machine, and wherein the snapshot copy of the virtual machine is a point-in-time copy that reflects locations of blocks of data stored in a data storage device.
9. The method of claim 7 , wherein creating the backup copy of the virtual machine comprises performing a streaming backup operation of the virtual machine to store a secondary copy of the virtual machine to magnetic tape storage media.
10. The method of claim 7 , further comprising: accessing a registry of the virtual machine to identify the one or more applications.
11. The method of claim 7 , wherein an application-specific data quiesces corresponding application into an application-consistent state prior to creating a snapshot copy of the corresponding application.
12. The method of claim 7 , further comprising discovering a SQL application, an Exchange application, an Oracle application, or a Sharepoint application.
13. A non-transitory, computer-readable medium having computer-executable instructions stored thereon that, when executed by one or more processors, cause a system to perform a plurality of operations for performing a data storage operation on a virtual machine, the plurality of operations comprising:
for one or more applications hosted by a virtual machine, injecting an application-specific data agent into the virtual machine,
wherein the injected data agent is configured to perform, at least, an application-specific backup job for the one or more applications that is executed in a specific virtual computing environment;
instructing each application-specific data agent injected into the virtual machine to perform an application-specific backup job,
wherein the application-specific backup job comprises creating a snapshot copy of the one or more applications;
creating a backup copy of the virtual machine by associating each snapshot copy of each discovered application with the backup copy of the virtual machine;
generating an index that comprises data imaged by snapshot copies of the one or more applications; and
mapping the generated index to an index of the backup copy of the virtual machine.
14. The non-transitory, computer-readable medium system of claim 13 , wherein creating the backup copy of the virtual machine comprises performing a snapshot operation of the virtual machine to create a snapshot copy of the virtual machine, and wherein the snapshot copy of the virtual machine is a point-in-time copy that reflects locations of blocks of data stored in a data storage device.
15. The non-transitory, computer-readable medium system of claim 13 , wherein creating the backup copy of the virtual machine comprises performing a streaming backup operation of the virtual machine to store a secondary copy of the virtual machine to magnetic tape storage media.
16. The non-transitory, computer-readable medium system of claim 13 , wherein the plurality of operations further comprises: accessing a registry of the virtual machine to identify the one or more applications.
17. The non-transitory, computer-readable medium system of claim 13 , wherein an application-specific data agent quiesces corresponding application into an application-consistent state prior to creating a snapshot copy of the corresponding application.
