Abstract

Sizing resources for a replication target, including: determining an initial resource requirement for a replication source; determining a retention resource requirement for the replication source; and reporting, in dependence on the initial resource requirement and the retention resource requirement, a total resource requirement for replicating the replication source.

First claim

What is claimed is:

1. A method comprising:
determining, for a storage object, a storage resource requirement for a replication target based on write activity at a replication source that accounts for an amount of overwrites associated with the storage object at the replication source; and
creating the replication target, wherein the replication target is sized based upon the storage resource requirement for the storage object.

2. The method of claim 1 wherein determining the storage resource requirement comprises:
determining a size of a footprint of a replication source; and
adjusting the size of the footprint to compensate for existing snapshots.

3. The method of claim 1 further comprising:
determining a retention resource requirement for a replication source, further comprising aggregating historical throughput over a time interval that corresponds to a retention period for a replication target.

4. The method of claim 3 wherein the time interval comprises a plurality of time periods and aggregating the historical throughput over the time interval comprises compensating for overwrites during each time period of the plurality of time periods.

5. The method of claim 4 wherein compensating for overwrites comprises estimating an amount of overwrites based on historical data.

6. The method of claim 1 further comprising:
determining an amount of potential deduplication between a replication source and at least one other data source; and
reporting a total resource requirement for replicating data from the replication source based on the amount of potential deduplication.

7. The method of claim 6 wherein reporting the total resource requirement for replicating the replication source is based on an expected growth rate of the replication source.

8. A storage system comprising:
a memory; and
a processor, operatively coupled to the memory, configured to:
determine, for a storage object, a storage resource requirement for a replication target based on write activity at a replication source that accounts for an amount of overwrites associated with the storage object at the replication source; and
create the replication target, wherein the replication target is sized based upon the storage resource requirement for the storage object.

9. The storage system of claim 8 , wherein the processor determining the storage resource requirement comprises:
determining a size of a footprint of a replication source; and
adjusting the size of the footprint to compensate for existing snapshots.

10. The storage system of claim 8 , the processor further configured to:
determine a retention resource requirement for a replication source, further comprising aggregating historical throughput over a time interval that corresponds to a retention period for a replication target.

11. The storage system of claim 10 wherein the time interval comprises a plurality of time periods and aggregating the historical throughput over the time interval comprises compensating for overwrites during each time period of the plurality of time periods.

12. The storage system of claim 11 wherein the processor compensating for overwrites comprises estimating an amount of overwrites based on historical data.

13. The storage system of claim 8 , the processor further configured to:
determine an amount of potential deduplication between a replication source and at least one other data source; and
report a total resource requirement for replicating data from the replication source based on the amount of potential deduplication.

14. The storage system of claim 13 wherein the processor reporting the total resource requirement for replicating the replication source is based on an expected growth rate of the replication source.

15. A non-transitory computer readable storage medium storing instructions, which when executed, cause a processor to:
determine, for a storage object, a storage resource requirement for a replication target based on write activity at a replication source that accounts for an amount of overwrites associated with the storage object at the replication source; and
create the replication target, wherein the replication target is sized based upon the storage resource requirement for the storage object.

16. The non-transitory computer readable storage medium of claim 15 , wherein the processor determining the storage resource requirement comprises:
determining a size of a footprint of a replication source; and
adjusting the size of the footprint to compensate for existing snapshots.

17. The non-transitory computer readable storage medium of claim 15 , the processor further configured to:
determine a retention resource requirement for a replication source, further comprising aggregating historical throughput over a time interval that corresponds to a retention period for a replication target.

18. The non-transitory computer readable storage medium of claim 17 wherein the time interval comprises a plurality of time periods and aggregating the historical throughput over the time interval comprises compensating for overwrites during each time period of the plurality of time periods.

19. The non-transitory computer readable storage medium of claim 18 wherein the processor compensating for overwrites comprises estimating an amount of overwrites based on historical data.
