Abstract

An apparatus, system, and method are disclosed for a virtual machine backup. A name module establishes an administrative machine name for a virtual machine. A space module associates at least one administrative name space with the administrative machine name. A backup module backs up files belonging to the virtual machine using a backup proxy, wherein the files are segregated under the administrative machine name and are accessible using only a secure key belonging to the virtual machine and without using a backup proxy secure key. A mask module masks out pathname components for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname.

Claims

1. A computer program product comprising a computer useable medium having a computer readable program stored on a tangible storage device, wherein the computer readable program when executed on a computer causes the computer to:

establish an administrative machine name for a virtual machine, the virtual machine comprising a unique security configuration, the security configuration comprising a secure key distinct from the administrative machine name and providing secure access to the virtual machine;

associate at least one administrative name space with the administrative machine name;

quiesce files belonging to the virtual machine;

create an incremental snapshot for the virtual machine;

back up the files belonging to the virtual machine to the at least one administrative machine name space with the administrative machine name and the secure key using a backup proxy with a security control comprising a backup proxy secure key used to access the backup proxy, the security control distinct from the security configuration, wherein the files are segregated under the administrative machine name and are only accessible using the secure key under the security configuration of the virtual machine;

mask out pathname components from the at least one administrative machine name space for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname; and

thaw the snapshot for the virtual machine.

2. The computer program product of claim 1, the computer readable program further causing the computer to discover each virtual machine eligible for backup.

3. The computer program product of claim 2, the computer readable program further causing the computer to prepare the virtual machine for backup.

4. The computer program product of claim 3, wherein a single command initiates the backup of a plurality of virtual machines.

5. The computer program product of claim 1, the computer readable program further causing the computer to establish at least one virtual disk in at least one administrative name space.

6. The computer program product of claim 1, the computer readable program further causing the computer to establish the administrative machine name using a Tivoli Storage Manager™

asnodename option compatible with a latest version of Tivoli Storage Manager software on Feb. 26, 2008.

7. The computer program product of claim 1, the computer readable program further causing the computer to mask out the pathname components using a Tivoli Storage Manager™

snapshotroot option compatible with a latest version of Tivoli Storage Manager software on Feb. 26, 2008.

8. An apparatus to back up a virtual machine, the apparatus comprising:

a storage device storing a computer readable program;

a processor executing the computer readable program, the computer readable program comprising;

a name module establishing an administrative machine name for a virtual machine, the virtual machine comprising a unique security configuration, the security configuration comprising a secure key distinct from the administrative machine name and providing secure access to the virtual machine;

a space module associating at least one administrative name space with the administrative machine name;

a backup module quiescing files belonging to the virtual machine, creating an incremental snapshot for the virtual machine, and backing up the files belonging to the virtual machine to the at least one administrative machine name space with the administrative machine name and the secure key using a backup proxy with a security control comprising a backup proxy secure key used to access the backup proxy, the security control distinct from the security configuration, wherein the files are segregated under the administrative machine name and are only accessible using the secure key under the security configuration of the virtual machine and thawing the snapshot for the virtual machine; and

a mask module masking out pathname components from the at least one administrative machine name space for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname.

9. The apparatus of claim 8, the executable code further comprising a control module to discover each virtual machine eligible for backup.

10. The apparatus of claim 9, the control module further preparing the virtual machine for backup.

11. The apparatus of claim 10, wherein a single command initiates the backup of a plurality of virtual machines.

12. A method for deploying computer infrastructure, comprising integrating a computer readable program stored on a tangible storage device into a computing system, wherein the program executed by the computing system performs the following:

discovering each virtual machine eligible for backup;

preparing each virtual machine for backup;

establishing an administrative machine name for each virtual machine, each virtual machine comprising a unique security configuration, the security configuration comprising a secure key distinct from the administrative machine name and providing secure access to the virtual machine;

associating at least one administrative name space with each administrative machine name;

quiescing files belonging to the virtual machine;

creating an incremental snapshot for the virtual machine;

backing up the files belonging to each virtual machine to the at least one administrative machine name space with the administrative machine name and the secure key using a backup proxy with a security control comprising a backup proxy secure key used to access the backup proxy, the security control distinct from the security configuration, wherein the files are segregated under each administrative machine name and are only accessible using the secure key under the security configuration of the virtual machine;

masking out pathname components from the at least one administrative machine name space for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname; and

thawing the snapshot for the virtual machine.

13. The method of claim 12, wherein a single command initiates the backup of a plurality of virtual machines.

14. A system to back up a virtual machine, the system comprising:

a computer executing a plurality of virtual machines;

a backup proxy backing up the plurality of virtual machines;

a name module establishing an administrative machine name for each virtual machine, each virtual machine comprising a unique security configuration, the security configuration comprising a secure key distinct from the administrative machine name and providing secure access to the virtual machine;

a space module associating at least one administrative name space with each administrative machine name;

a backup module quiescing files belonging to the virtual machine, creating an incremental snapshot for the virtual machine, and backing up the files belonging to each virtual machine to the at least one administrative machine name space with the administrative machine name and the secure key using a backup proxy with a security control comprising a backup proxy secure key used to access the backup proxy, the security control distinct from the security configuration, wherein the files are segregated under the administrative machine name and are only accessible using the secure key under the security configuration of each virtual machine and thawing the snapshot for the virtual machine; and

a mask module masking out pathname components from the at least one administrative machine name space for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname, wherein each module is embodied in a storage device storing a computer readable program and a processor executing the computer readable program.
