Abstract

A system and method for choosing a stream to transfer data is described. In some cases, the system reviews running data storage operations and chooses a data stream based on the review. In some cases, the system chooses a stream based on the load of data to be transferred.

Claims

1. A computer-implemented method of modifying the performance of data storage operations, the method comprising:

automatically identifying an estimated time of completion for a set of data storage operations;

automatically comparing the estimated time of completion with a pre-determined allocated time for the data storage operations; and

when the estimated time is greater than the allocated time, automatically implementing one or more corrective measures to the data storage operations.

2. The method of claim 1, wherein implementing one or more corrective measures includes allocating additional storage resources to the data storage operation.

3. The method of claim 1, wherein implementing one or more corrective measures includes selecting a subset of data storage operations and completing the selected subset of data storage operations before performing unselected data storage operations.

4. The method of claim 1, wherein implementing one or more corrective measures includes transferring some or all remaining data storage operations to alternate storage resources.

5. The method of claim 1, wherein implementing one or more corrective measures includes reorganizing data storage operations based on performance of storage resources.

6. A system of monitoring data storage operations being performed within a time window, comprising:

a time monitoring component, wherein the time monitoring component compares operation time of storage operations with the time window; and

a storage modification component, communicating with the time monitoring component, wherein the storage modification component modifies data storage operations based on information received from the time monitoring component.

7. The system of claim 6, wherein the time monitoring component continuously compares the operation time of storage operations with the time window.

8. The system of claim 6, wherein the time monitoring component compares the operation time of storage operations with the time window at pre-determined intervals within the time window.

9. The system of claim 6, wherein the storage modification component modifies data storage operations to be performed within the current time window.

10. The system of claim 6, wherein the storage modification component modifies data storage operations to be performed within a future time window.

11. A method of dynamically selecting jobs of data to be transferred from a file system to data storage devices during at least one data storage operation, the method comprising:

determining an estimated time of completion of performing all pending jobs and transferring data from the file system to the storage devices;

when the estimated time of completion is greater than a threshold time of completion;

ordering the pending jobs based on a determined priority; and

performing jobs with a higher priority before jobs with a lower priority for transferring data from the file system to the storage devices.

12. The method of claim 11, wherein the priority is based on the type of data within the jobs.

13. The method of claim 11, wherein the priority is determined before the jobs are to be transferred.

14. The method of claim 11, wherein the priority is determined based on the time comparison.

15. The method of claim 11, wherein the priority is determined based on input received from a user related to the data storage operation.

16. The method of claim 11, further comprising:

receiving information related to previous data storage operations; and

determining the priority of jobs based on the received information.

17. The method of claim 11, further comprising:

receiving information related to performance of resources utilized by the data storage operation; and

determining the priority of jobs based on the received information.

18. The method of claim 11, further comprising:

transferring at least some of the lower priority jobs to a future data storage operation.

19. The method of claim 11, further comprising:

transferring at least some of the lower priority jobs to alternate resources.
