Abstract

Various systems and methods to display information regarding duplication operations and to configure duplication operations. For example, information regarding policies that can be included in a duplication operation is presented via a display. The display receives selection of one or more of the policies. In response to the selection, the display updates to reflect how much of a bucket has been allocated and how much is available, where the bucket specifies an amount of time and is calculated as a function of a duplication window duration.

Claims

1. A method comprising:

receiving information specifying a duplication window duration, in which a duplication operation is to be performed;

calculating a bucket length as a function of the duplication window duration, wherein

the bucket length is calculated prior to performing the duplication operation, and

the bucket length comprises a portion of the duplication window duration;

generating a display comprising information identifying the bucket length, a plurality of policies, an estimated time to duplicate at least one policy of the plurality of policies, an allocated time, or an available time;

receiving a selection of the at least one policy , wherein

the selection indicates that the at least one policy is to be included in the duplication operation and migrated from a source storage device to a target storage device;

determining whether including the at least one policy in the duplication operation would cause the estimated time to exceed the bucket length; and

if the including will not cause the estimated time to exceed the bucket length, updating the display using the estimated time, and

performing the duplication operation, wherein

the performing comprises

locating a most recent backup image on the source storage device, and

copying the most recent backup image from the source storage device to the target storage device.

2. The method of claim 1, wherein

the bucket length is greater than the duplication window duration.

3. The method of claim 1, further comprising:

detecting that the estimated time to duplicate the at least one policy exceeds the duplication window duration; and

preventing selection of additional policies of the plurality of policies, in response to the detecting.

4. The method of claim 1, further comprising:

detecting that the estimated time to duplicate the at least one policy exceeds the duplication window duration; and

generating a notification, in response to the detecting, wherein

the notification comprises information indicating that the estimated time to duplicate the at least one policy exceeds the duplication window duration.

5. The method of claim 1, further comprising:

updating the at least one policy in response to detecting that the most recent backup image has been copied to the target storage device, wherein

the updating the at least one policy comprises changing a destination value in the at least one policy from the source storage device to the target storage device.

6. The method of claim 1, wherein

copying the most recent backup image from the source storage device to the target storage device does not include backup images which are not most recent backup images.

7. The method of claim 1, wherein

the updating the display comprises adding the estimated time to the allocated time and reducing the available time by the estimated time.

8. The method of claim 1, wherein

the portion of the bucket length is a percentage of the duplication window duration.

9. A non-transitory computer readable storage medium storing program instructions executable to:

receive information specifying a duplication window duration, in which a duplication operation is to be performed;

calculate a bucket length as a function of the duplication window duration, wherein

the bucket length is calculated prior to performing the duplication operation, and

the bucket length comprises a portion of the duplication window duration;

generate a display comprising information identifying the bucket length, a plurality of policies, an estimated time to duplicate at least one policy of the plurality of policies, an allocated time, or an available time;

receive a selection of the at least one policy , wherein

the selection indicates that the at least one policy is to be included in the duplication operation and migrated from a source storage device to a target storage device;

determine whether including the at least one policy in the duplication operation would cause the estimated time to exceed the bucket length; and

if the including will not cause the estimated time to exceed the bucket length,

update the display using the estimated time, and

perform the duplication operation, wherein

the performing comprises

locating a most recent backup image on the source storage device, and

copying the most recent backup image from the source storage device to the target storage device.

10. The non-transitory computer readable storage medium of claim 9, wherein

the bucket length is greater than the duplication window duration.

11. The non-transitory computer readable storage medium of claim 9, wherein the instructions are further executable to:

detect that the estimated time to duplicate the at least one policy exceeds the duplication window duration;

generate a notification, in response to the detecting, wherein

the notification comprises information indicating that the estimated time to duplicate the at least one policy exceeds the duplication window duration; and

prevent selection of additional policies of the plurality of policies, in response to the detecting.

12. The non-transitory computer readable storage medium of claim 9, further comprising:

updating the at least one policy in response to detecting that the most recent backup image has been copied to the target storage device, wherein

the updating the at least one policy comprises changing a destination value in the at least one policy from the source storage device to the target storage device.

13. The non-transitory computer readable storage medium of claim 9, wherein

copying the most recent backup image from the source storage device to the target storage device does not include backup images which are not most recent backup images.

14. The non-transitory computer readable storage medium of claim 9, wherein

the updating the display comprises adding the estimated time to the allocated time and reducing the available time by the estimated time.

15. The non-transitory computer readable storage medium of claim 9, wherein

the portion of the bucket length is a percentage of the duplication window duration.

16. A system comprising:

one or more processors; and

a memory coupled to the one or more processors, wherein the memory stores program instructions executable by the one or more processors to;

receive information specifying a duplication window duration, in which a duplication operation is to be performed;

calculate a bucket length as a function of the duplication window duration, wherein

the bucket length is calculated prior to performing the duplication operation, and

the bucket length comprises a portion of the duplication window duration;

generate a display comprising information identifying the bucket length, a plurality of policies, an estimated time to duplicate at least one policy of the plurality of policies, an allocated time, or an available time;

receive a selection of the at least one policy , wherein

the selection indicates that the at least one policy is to be included in the duplication operation and migrated from a source storage device to a target storage device;

determine whether including the at least one policy in the duplication operation would cause the estimated time to exceed the bucket length; and

if the including will not cause the estimated time to exceed the bucket length,

update the display using the estimated time, and

perform the duplication operation, wherein

the performing comprises

locating a most recent backup image on the source storage device, and

copying the most recent backup image from the source storage device to the target storage device.

17. The system of claim 16, wherein

the bucket length is greater than the duplication window duration.
