Abstract

A method for improving performance of data container backups comprises identifying a data container on a source computer to be backed up. A snapshot image of the data container is generated, wherein the snapshot image comprises one or more partitions. Data is read simultaneously from each of the one or more partitions to a destination computer over one or more transport paths. Each of the one or more transport paths comprises one or more threads. The data read to the destination computer is backed up such that the data retains a physical block sequence of the data container.

Claims

1. A method for improving performance of data container backups, the method comprising the steps of:

identifying a data container on a source computer to be backed up;

generating a snapshot image of the data container, wherein the snapshot image comprises one or more partitions;

reading data simultaneously from each of the one or more partitions to a destination computer over one or more transport paths, wherein each of the one or more transport paths comprises one or more threads; and

backing up the data read to the destination computer, such that the data retains a physical block sequence of the data container.

2. The method of claim 1, wherein the data container comprises a virtual machine and the partitions of the snapshot image comprise virtual machine disks.

3. The method of claim 2, wherein the source computer employs virtualization technology that allows creating and accessing the snapshot image of the virtual machine through an interface.

4. The method of claim 2, wherein generating a snapshot image generates the snapshot image of a virtual machine;

and

wherein reading the data uses a vendor specific interface to read the data.

5. The method of claim 1, wherein the one or more transport paths comprise one or more Ethernet connections and fibre channel Logical Unit Numbers (LUNs).

6. The method of claim 1, wherein reading data further comprises determining available transport paths for obtaining the data.

7. The method of claim 6, wherein one or more of the available transport paths are used to obtain the data from each partition.

8. The method of claim 6, wherein the transport paths are chosen in an optimal way based on available bandwidth of each transport path.

9. The method of claim 1, wherein the reading step further comprises accessing the data simultaneously from different offsets in a partition using the one or more threads.

10. The method of claim 1, wherein the reading step comprises using one of a pre-configured number of threads or dynamically selected number of threads to read the data.

11. The method of claim 1, wherein the destination computer is a server located remotely to the source computer.

12. A system for improving performance of data container backups, the system comprising:

a processor-controlled server, the server comprising;

a memory;

a snapshot module being operable to;

identify a data container on a source computer to be backed up;

generate a snapshot image of the data container, wherein the snapshot image comprises one or more partitions;

a reading module being operable to read data simultaneously from each of the one or more partitions to a destination computer over one or more transport paths, wherein each of the one or more transport paths comprises one or more threads; and

a backup module being operable to back up the data read to the destination computer, such that the data retains a physical block sequence of the data container.

13. The system of claim 12, wherein the data container comprises a virtual machine and the partitions of the snapshot image comprise virtual machine disks.

14. The system of claim 12, wherein the reading module is further configured to access the data simultaneously from different offsets in a partition using the multiple threads.

15. The system of claim 12, wherein the reading module is further operable to determine available transport paths for obtaining the data.

16. The system of claim 15, wherein one or more of the available transport paths are used to obtain the data from each partition.

17. The system of claim 15, wherein the transport paths are chosen in an optimal way based on available bandwidth of each transport path.

18. Logic encoded in a tangible computer readable media, the logic operable when executed by a computer to:

identify a data container on a source computer to be backed up;

generate a snapshot image of the data container, wherein the snapshot image comprises one or more partitions;

read data simultaneously from each of the one or more partitions to a destination computer over one or more transport paths, wherein each of the one or more transport paths comprises one or more threads; and

back up the data read to the destination computer, such that the data retains a physical block sequence of the data container.

19. The logic of claim 18, wherein the logic is further operable to determine available transport paths for obtaining the data.

20. The logic of claim 19, wherein the transport paths are chosen in an optimal way based on available bandwidth of each transport path.
