Abstract

Examples include selection of a remote object storage system for a deduplication data item. Some examples may include determination of an expected usage frequency for the deduplication data item, selection of a remote object cloud storage system based on the expected usage frequency for the data item, and provision of the deduplication data item to the selected remote object storage system for storage as an object in the selected remote object storage system.

Claims

1. A method comprising:

receiving, at a computing device from a deduplication system, a deduplication data item to be stored in one of a plurality of remote object storage systems and storage selection criteria; and

selecting one of the remote object storage systems based on the received storage selection criteria; and

providing the deduplication data item to the selected remote object storage system for storage as an object in the selected remote object storage system.

2. The method of claim 1, wherein the storage selection criteria comprises one or more of an object name of the deduplication data item, a property of storage for the deduplication data item, and a property of data in the deduplication data item.

3. The method of claim 1, comprising determining an expected access frequency of the deduplication data item from the storage selection criteria, wherein selecting one of the remote object storage systems based on the received storage selection criteria comprises selecting one of the remote storage systems based on the expected access frequency.

4. The method of claim 3, comprising determining the expected usage frequency from a type of the deduplication data item.

5. The method of claim 4, wherein determining the expected usage frequency from a type of the deduplication data item comprises determining the expected usage frequency based on whether the deduplication data item is a data chunk or a deduplication metadata.

6. The method of claim 1, comprising selecting one of the remote object storage systems based on a respective property of each of the remote object storage systems.

7. The method of claim 6, wherein the respective property of each of the remote object storage systems comprises at least one of a respective access throughput, access latency, access cost and storage cost of each of the remote object storage systems.

8. A system comprising:

at least one processing resource; and

a machine-readable storage medium comprising instructions executable by the at least one processing resource to;

identify a type of a data item to be stored in one of a plurality of remote object storage systems, based on a provided object name to be used for the data item;

determine an anticipated access rate for the data item based on the identified type of the data item;

select one of the remote object storage systems based on the anticipated access rate for the data item; and

instruct the selected remote object storage system to store the data item as an object with the provided object name.

9. The system of claim 8, wherein the machine-readable storage medium comprises instructions executable by the at least one processing resource to receive the data item from a deduplication system.

10. The system of claim 8, wherein the one of the remote object storage systems is further selected based on a property of storage for the deduplication data item, and a property of data in the deduplication data item.

11. The system of claim 8, wherein the machine-readable storage medium comprises instructions executable by the at least one processing resource to select one of the remote object storage systems based further on a respective property of each of the remote object storage systems.

12. The system of claim 11, wherein the respective property of each of the remote object storage systems comprises one of a respective access throughput, access latency, access cost and storage cost of each of the remote object storage systems.

13. A computer-readable storage medium comprising instructions that, when executed by a processing apparatus, cause the processing apparatus to:

identify whether a deduplication data item to be stored in one of a plurality of remote object storage systems is of a deduplication metadata type or a chunk data type, based on a provided object name to be used for storing the data item as an object;

when the data item is identified as being of the deduplication metadata type, select a first remote object storage systems of a plurality of remote object storage systems;

when the data item is identified as being of the data chunk type, select a second remote object storage systems of the plurality of remote object storage systems; and

instruct the selected remote object storage system to store the data item as an object with the provided object name.

14. The computer-readable storage medium of claim 13, comprising instructions that, when executed by a processing apparatus, cause the processing apparatus to determine the expected access frequency of the data item based on whether the data item is of the deduplication metadata type or the chunk data type, and to select the first or second remote object storage system based on the expected access frequency of the data item.

15. The computer-readable storage medium of claim 13, comprising instructions that, when executed by a processing apparatus, cause the processing apparatus to select the first or second remote object storage system based further on a property of the first remote object storage system and a property of the second remote object storage system.

16. The computer-readable storage medium of claim 15, wherein the respective property of each of the remote object storage systems comprises at least one of a respective access throughput, access latency, access cost and storage cost of each of the remote object storage systems.
