Abstract

A system for improving backup performance includes an interface, a processor, and a memory. The interface is to receive a volume identifier to backup. The processor is to determine allocation for data of a volume associated with the volume identifier in a plurality of storage tiers to improve backup processing, move data based at least in part on the allocation, and backup data of the volume. The memory is coupled to the processor and configured to provide the processor with instructions.

Claims

1. A system for improving backup performance comprising:

an interface to;

receive a volume identifier to backup;

a processor to;

determine allocation for data of a volume associated with the volume identifier in a plurality of storage tiers to improve backup processing;

move data based at least in part on the allocation;

backup data of the volume; and

a memory coupled to the processor and configured to provide the processor with instructions.

2. A system as in claim 1, wherein determining allocation comprises determining available storage in a plurality of storage tiers.

3. A system as in claim 1, wherein determining allocation is based at least in part on percentage of data that has changed in the volume.

4. A system as in claim 1, wherein determining allocation is based at least in part on time remaining until backup.

5. A system as in claim 1, wherein determining allocation is based at least in part on number of storage tiers.

6. A system as in claim 1, wherein determining allocation is based at least in part on performance of each of the plurality of storage tiers.

7. A system as in claim 1, wherein determining allocation comprises determining a cost function.

8. A system as in claim 7, wherein the cost function includes a cost of moving data between a tier and a second tier.

9. A system as in claim 8, wherein the cost of moving data is based at least in part on a moving time.

10. A system as in claim 8, wherein the cost of moving data is based at least in part on a system load.

11. A system as in claim 8, wherein the cost of moving is based at least in part on a bandwidth limit for moving.

12. A system as in claim 7, wherein the cost function is based at least in part on a current storage tier of the data.

13. A system as in claim 1, wherein the plurality of storage tiers includes a slower storage tier and a faster storage tier.

14. A system as in claim 13, wherein moving data from the slower storage tier to the faster storage tier.

15. A system as in claim 13, wherein moving data from the faster storage tier to the slower storage tier.

16. A system as in claim 1, wherein the processor is further to determine a second allocation for after backing up the data of the volume.

17. A system as in claim 16, wherein the processor is further to move data according to the second allocation after backing up the data of the volume.

18. A system as in claim 16, wherein the second allocation is based at least in part on optimizing access to data.

19. A method of improving backup performance, comprising:

receiving a volume identifier to backup;

determining, using a processor, allocation for data of a volume associated with the volume identifier in a plurality of storage tiers to improve backup processing;

moving data based at least in part on the allocation; and

backing up data of the volume.

20. A computer program product for improving backup performance, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a volume identifier to backup;

determining, using a processor, allocation for data of a volume associated with the volume identifier in a plurality of storage tiers to improve backup processing;

moving data based at least in part on the allocation; and

backing up data of the volume.
