Abstract

In some embodiments, a method is provided and a computer accessible medium comprising instructions which, when executed, implement the method is also provided. A recovery time for recovery of at least one asset is estimated responsive to at least one metric represented in metric data. The metric data is accumulated prior to the estimation. In various embodiments, data protection operations may include one or more of asset copy operations, recovery operations, etc. The estimated recovery time may be reported to a user. In other embodiments, metric data may be used to validate recoverability. In still other embodiments, recovery metrics may be calculated and displayed to the user along with corresponding recovery targets and objectives.

Claims

1. A method comprising:

a computer estimating a recovery time for recovery of at least one asset responsive to at least one metric represented in metric data accumulated prior to the estimating;

the computer reporting the estimated recovery time to a user;

the computer selecting one of a plurality of methods to calculate one or more recovery metrics, each of the plurality of methods having a different level of accuracy;

the computer calculating the one or more recovery metrics responsive to the selected method; and

the computer reporting the one or more recovery metrics to the user.

2. The method as recited in claim 1 wherein at least a portion of the metric data is accumulated during one or more data protection operations.

3. The method as recited in claim 2 wherein the one or more data protection operations comprise one or more previously performed asset copy operations.

4. The method as recited in claim 2 wherein the one or more data protection operations comprise one or more previously performed recovery operations.

5. The method as recited in claim 2 wherein the one or more data protection operations comprise one or more previously performed testing operations, each testing operation testing one or more aspects of recovery.

6. The method as recited in claim 2 wherein the one or more data protection operations comprise one or more previously performed simulations.

7. The method as recited in claim 2 wherein the one or more data protection operations comprise one or more previously performed test recovery operations.

8. The method as recited in claim 2 further comprising:

measuring at least one metric during one of the one or more data protection operations; and

representing the metric in the metric data.

9. The method as recited in claim 1 wherein the selecting is automatic based on availability of data used by the plurality of methods in the metric data.

10. The method as recited in claim 1 wherein the selecting is performed responsive to user input.

11. The method as recited in claim 1 further comprising presenting the level of accuracy corresponding to the selected one of the plurality of methods to the user.

12. The method as recited in claim 11 further comprising accepting user input to select a different one of the plurality of methods having a higher level of accuracy than the selected one of the plurality of methods.

13. The method as recited in claim 1 further comprising presenting the one or more recovery metrics, a corresponding one or more recovery targets, and a corresponding one or more recovery objectives to the user.

14. The method as recited in claim 13 further comprising:

modifying a protection configuration;

recalculating the one or more recovery metrics responsive to the modifying; and

presenting the recalculated one or more recovery metrics, the corresponding one or more recovery targets, and the corresponding one or more recovery objectives to the user.

15. The method as recited in claim 1 wherein at least a portion of the metric data is accumulated during operation of the at least one asset.

16. The method as recited in claim 1 wherein the metric data includes one or more metrics accumulated by a performance monitoring tool.

17. A non-transitory computer accessible storage medium storing a plurality of instructions comprising instructions which, when executed on a computer, implement a method comprising:

estimating a recovery time for recovery of at least one asset responsive to at least one metric represented in metric data accumulated prior to the estimating;

reporting the estimated recovery time to a user;

selecting one of a plurality of methods to calculate one or more recovery metrics, each of the plurality of methods having a different level of accuracy;

calculating the one or more recovery metrics responsive to the selected method; and

reporting the one or more recovery metrics to the user.

18. The non-transitory computer accessible storage medium as recited in claim 17 wherein at least a portion of the metric data is accumulated during one or more data protection operations.

19. The non-transitory computer accessible storage medium as recited in claim 18 wherein the one or more data protection operations comprise one or more previously performed asset copy operations.

20. The non-transitory computer accessible storage medium as recited in claim 18 wherein the one or more data protection operations comprise one or more previously performed recovery operations.

21. The non-transitory computer accessible storage medium as recited in claim 18 wherein the one or more data protection operations comprise one or more previously performed testing operations, each testing operation testing one or more aspects of recovery.

22. The non-transitory computer accessible storage medium as recited in claim 18 wherein the one or more data protection operations comprise one or more previously performed simulations.

23. The non-transitory computer accessible storage medium as recited in claim 18 wherein the one or more data protection operations comprise one or more previously performed test recovery operations.

24. The non-transitory computer accessible storage medium as recited in claim 18 wherein the method further comprises:

measuring the at least one metric during one of the one or more data protection operations; and

representing the metric in the metric data.

25. The non-transitory computer accessible storage medium as recited in claim 17 wherein the selecting is automatic based on availability of data used by the plurality of methods in the metric data.

26. The non-transitory computer accessible storage medium as recited in claim 17 wherein the selecting is performed responsive to user input.

27. The non-transitory computer accessible storage medium as recited in claim 17 further comprising presenting the level of accuracy corresponding to the selected one of the plurality of methods to the user.

28. The non-transitory computer accessible storage medium as recited in claim 27 further comprising accepting user input to select a different one of the plurality of methods having a higher level of accuracy than the selected one of the plurality of methods.

29. The non-transitory computer accessible storage medium as recited in claim 17 wherein the method further comprises presenting the one or more recovery metrics, a corresponding one or more recovery targets, and a corresponding one or more recovery objectives to the user.

30. The non-transitory computer accessible storage medium as recited in claim 17 wherein the method further comprises:

modifying a protection configuration;

recalculating the one or more recovery metrics responsive to the modifying; and

presenting the recalculated one or more recovery metrics, the corresponding one or more recovery targets, and the corresponding one or more recovery objectives to the user.

31. The non-transitory computer accessible storage medium as recited in claim 17 wherein at least a portion of the metric data is accumulated during operation of the at least one asset.
