Data protection object store

1. A system comprising:

an object store; wherein the object store has a set of objects corresponding to a copy of LUN at a point in time (PIT) on a production site;

a data protection appliance (DPA) on the production site;

computer-executable logic operating in memory, wherein the computer-executable program logic enables execution across the one or more processors of:

splitting IO from a LUN on the production site to a DPA;

accumulating IO at the DPA until a threshold of IO is reached;

upon reaching the threshold, sending an object containing the IO to the object store.

2. The system of claim 1 , wherein the logic further enables:

accumulating metadata describing the accumulated IO at the DPA until a threshold is reached;

upon reaching the threshold, sending an object containing the accumulated metadata to the object store.

3. The system of claim 2 , wherein the logic further enables:

periodically processing received objects containing IO in the object store and received objects containing the metadata in the object store to create a new PIT in the object store.

4. The system of claim 3 wherein the processing includes:

determining from the received objects containing the metadata what objects of the set of objects corresponding to the copy of LUN at the PIT need to be rewritten; and

creating new objects corresponding to the what objects need to be rewritten.

5. The system of claim 4 , wherein the logic further enables:

creating a new metadata object describing the new point of time; wherein the metadata object includes references to the objects that make up the new PIT.

6. The system of claim 3 , wherein the logic further enables:

creating a journal; wherein the journal enables the new PIT to be rolled to the old PIT.

7. A computer implemented method comprising:

splitting IO from a LUN on a production site to a data protection appliance (DPA);

accumulating IO at the DPA until a threshold of IO is reached;

upon reaching the threshold, sending an object containing the IO to an object store.

8. The method of claim 7 further comprising:

accumulating metadata describing the accumulated IO at the DPA until a threshold is reached;

upon reaching the threshold, sending an object containing the accumulated metadata to the object store.

9. The method of claim 8 further comprising:

periodically processing received objects containing IO in the object store and received objects containing the metadata in the object store to create a new PIT in the object store.

10. The method of claim 9 wherein the processing includes:

determining from the received objects containing the metadata what objects of the set of objects corresponding to the copy of LUN at the PIT need to be rewritten; and

creating new objects corresponding to the what objects need to be rewritten.

11. The method of claim 10 further comprising:

creating a new metadata object describing the new point of time; wherein the metadata object includes references to the objects that make up the new PIT.

12. The method of claim 9 further comprising:

creating a journal; wherein the journal enables the new PIT to be rolled to the old PIT.

13. A computer program product comprising:

computer-executable logic stored on a non-transitory computer readable medium wherein the computer-executable program logic enables execution across the one or more processors of:

splitting IO from a LUN on a production site to a data protection appliance (DPA);

accumulating IO at the DPA until a threshold of IO is reached;

upon reaching the threshold, sending an object containing the IO to an object store.

14. The computer program product of claim 13 , wherein the logic further enables:

accumulating metadata describing the accumulated IO at the DPA until a threshold is reached;

upon reaching the threshold, sending an object containing the accumulated metadata to the object store.

15. The computer program product of claim 14 , wherein the logic further enables:

periodically processing received objects containing IO in the object store and received objects containing the metadata in the object store to create a new PIT in the object store.

16. The computer program product of claim 15 wherein the processing includes:

determining from the received objects containing the metadata what objects of the set of objects corresponding to the copy of LUN at the PIT need to be rewritten; and

creating new objects corresponding to the what objects need to be rewritten.

17. The computer program product of claim 16 , wherein the logic further enables:

creating a new metadata object describing the new point of time; wherein the metadata object includes references to the objects that make up the new PIT.

18. The computer program product of claim 15 , wherein the logic further enables:

creating a journal; wherein the journal enables the new PIT to be rolled to the old PIT.
