Abstract

Disclosed is a method, apparatus, and system for dynamically changing a backup policy, the operations comprising: automatically detecting a change in a backup source system; automatically activating a new backup policy, wherein the new backup policy is determined based on the change in the backup source system and an old backup policy; and performing a backup session based on the new backup policy.

First claim

1 . A computer-implemented method for dynamically changing a backup policy, the method comprising:
automatically detecting a change in a backup source system; automatically determining whether an old backup policy in combination with the change in the backup source system would lead to a failure in fulfillment of a backup service level objective; in response to determining that the old backup policy in combination with the change in the change in the backup source system would lead to a failure in fulfillment of the backup service level objective, automatically determining a new backup policy based on the change in the backup source system, the old backup policy, and the backup service level objective, wherein the new backup policy in combination with the change in the backup source system leads to a fulfillment of the backup service level objective; automatically activating the new backup policy; and performing a backup session based on the new backup policy.

2 . The method of claim 1 , wherein the backup source system comprises a virtual machine running on a hardware host.

3 . The method of claim 1 , wherein the change in the backup source system comprises at least one of: a change in usage patterns, or a change in underlying hardware.

4 . The method of claim 1 , wherein activating a new backup policy comprises one of: changing a backup frequency, changing a backup storage location, changing a backup window duration, or changing a start/stop time of a backup window.

5 . (canceled)

6 . The method of claim 1 , wherein a backup frequency is increased in response to a degradation of a solid state drive in the backup source system.

7 . The method of claim 1 , wherein a backup storage location is changed to a higher performance location in response to an increase in storage performance in the backup source system.

8 . A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor, cause the processor to perform operations for dynamically changing a backup policy, the operations comprising:
automatically detecting a change in a backup source system; automatically determining whether an old backup policy in combination with the change in the backup source system would lead to a failure in fulfillment of a backup service level objective; in response to determining that the old backup policy in combination with the change in the change in the backup source system would lead to a failure in fulfillment of the backup service level objective, automatically determining a new backup policy based on the change in the backup source system, the old backup policy, and the backup service level objective, wherein the new backup policy in combination with the change in the backup source system leads to a fulfillment of the backup service level objective; automatically activating the new backup policy; and performing a backup session based on the new backup policy.

9 . The non-transitory machine-readable medium of claim 8 , wherein the backup source system comprises a virtual machine running on a hardware host.

10 . The non-transitory machine-readable medium of claim 8 , wherein the change in the backup source system comprises at least one of: a change in usage patterns, or a change in underlying hardware.

11 . The non-transitory machine-readable medium of claim 8 , wherein activating a new backup policy comprises one of: changing a backup frequency, changing a backup storage location, changing a backup window duration, or changing a start/stop time of a backup window.

12 . (canceled)

13 . The non-transitory machine-readable medium of claim 8 , wherein a backup frequency is increased in response to a degradation of a solid state drive in the backup source system.

14 . The non-transitory machine-readable medium of claim 8 , wherein a backup storage location is changed to a higher performance location in response to an increase in storage performance in the backup source system.

15 . A data processing system, comprising:
a processor; and a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations for dynamically changing a backup policy, the operations including:
automatically detecting a change in a backup source system;
automatically determining whether an old backup policy in combination with the change in the backup source system would lead to a failure in fulfillment of a backup service level objective;
in response to determining that the old backup policy in combination with the change in the change in the backup source system would lead to a failure in fulfillment of the backup service level objective, automatically determining a new backup policy based on the change in the backup source system, the old backup policy, and the backup service level objective, wherein the new backup policy in combination with the change in the backup source system leads to a fulfillment of the backup service level objective;
automatically activating the new backup policy; and
performing a backup session based on the new backup policy.

16 . The data processing system of claim 15 , wherein the backup source system comprises a virtual machine running on a hardware host.

17 . The data processing system of claim 15 , wherein the change in the backup source system comprises at least one of: a change in usage patterns, or a change in underlying hardware.

18 . The data processing system of claim 15 , wherein activating a new backup policy comprises one of: changing a backup frequency, changing a backup storage location, changing a backup window duration, or changing a start/stop time of a backup window.

19 . (canceled)

20 . The data processing system of claim 15 , wherein a backup frequency is increased in response to a degradation of a solid state drive in the backup source system.

21 . The data processing system of claim 15 , wherein a backup storage location is changed to a higher performance location in response to an increase in storage performance in the backup source system.
