Abstract

A computer implemented method, system, and computer program product comprising intercepting an interaction with a data storage capability at the abstraction layer enabled to intercept data interactions for different types of data storage capabilities; wherein the interaction changes data on the data storage capability; sending a copy of the interaction to a replication data storage capability; and sending the interaction to the data storage capability.

Claims

1. A system comprising:

at least one processor; and

a memory configured to store one or more processor-executable instructions implementing a set of abstraction layers including an object abstraction layer, a database abstraction layer, and a file system abstraction layer, the set of abstraction layers being configured to intercept a plurality of interactions with different data storage capabilities, the data storage capabilities comprising an object store, a database, and a file system,

wherein, when executed by the at least one processor, the one or more processor-executable instructions cause the at least one processor to;

intercept the plurality of interactions by using the set of abstraction layers, wherein intercepting the plurality of interactions includes;

(i) intercepting an object interaction with the object abstraction layer, (ii) intercepting a database interaction with the database abstraction layer, and (iii) intercepting a file system interaction with the file system abstraction layer;

split the plurality of interactions by using the set of abstraction layers, wherein splitting the plurality of interactions includes;

(i) splitting the object interaction with the object abstraction layer, (ii) splitting the database interaction with the database abstraction layer, and (iii) splitting the file system interaction with the file system abstraction layer;

quiesce each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer by refraining from sending acknowledgements for intercepted data;

flush each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer; and

create a consistent point-in-time across each of the data storage capabilities after the object abstraction layer, the database abstraction layer, and the file system abstraction layer have been flushed.

2. The system of claim 1 wherein the set of abstraction layers includes a different abstraction layer for each type of data storage capability.

3. The system of claim 2 wherein the data storage capabilities further comprise a file and a volume.

4. The system of claim 1 wherein the set of abstraction layers enables generation of a consistent point in time across the data storage capabilities.

5. A computer implemented method comprising:

intercepting a plurality of interactions by using a set of abstraction layers including an object abstraction layer, a database abstraction layer, and a file system abstraction layer, wherein intercepting the plurality of interactions includes;

(i) intercepting an object interaction with the object abstraction layer, (ii) intercepting a database interaction with the database abstraction layer, and (iii) intercepting a file system interaction with the file system abstraction layer;

splitting the plurality of interactions by using the set of abstraction layers, wherein splitting the plurality of interactions includes;

(i) splitting the object interaction with the object abstraction layer, (ii) splitting the database interaction with the database abstraction layer, and (iii) splitting the file system interaction with the file system abstraction layer;

quiescing each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer by refraining from sending acknowledgements for intercepted data;

flushing each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer, and

creating a consistent point-in-time across each of a plurality of data storage capabilities after the object abstraction layer, the database abstraction layer, and the file system abstraction layer have been flushed, the plurality of data storage capabilities including an object store, a database, and a file system.

6. The method of claim 5 wherein the set of abstraction layers includes a different abstraction layer for each type of data storage capability.

7. The method of claim 6 wherein the data storage capabilities further comprise a file and a volume.

8. The method of claim 5 wherein the set of abstraction layers enables generation of a consistent point in time across the data storage capabilities.

9. A computer program product comprising:

a non-transitory computer readable medium encoded with computer executable program code, wherein the code enables execution across one or more processors of;

intercepting a plurality of interactions by using a set of abstraction layers including an object abstraction layer, a database abstraction layer, and a file system abstraction layer, wherein intercepting the plurality of interactions includes;

(i) intercepting an object interaction with the object abstraction layer, (ii) intercepting a database interaction with the database abstraction layer, and (iii) intercepting a file system interaction with the file system abstraction layer;

splitting the plurality of interactions by using the set of abstraction layers, wherein splitting the plurality of interactions includes;

(i) splitting the object interaction with the object abstraction layer, (ii) splitting the database interaction with the database abstraction layer, and (iii) splitting the file system interaction with the file system abstraction layer;

quiescing each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer by refraining from sending acknowledgements for intercepted data;

flushing each of the object abstraction layer, the database abstraction layer, and the file system abstraction layer, and

creating a consistent point-in-time across each of a plurality of data storage capabilities after the object abstraction layer, the database abstraction layer, and the file system abstraction layer have been flushed, the plurality of data storage capabilities including an object store, a database, and a file system.

10. The computer program product of claim 9 wherein the set of abstraction layers includes a different abstraction layer for each type of data storage capability.

11. The computer program product of claim 10 wherein the data storage capabilities further comprise a file and a volume.

12. The computer program product of claim 9 wherein the set of abstraction layers enables generation of a consistent point in time across the data storage capabilities.

13. The computer program product of claim 9 wherein the set of abstraction layers marks a point in time using a timestamp for each data storage capability.

14. The computer program product of claim 9 wherein the database interaction includes a SQL database interaction.
