Abstract

A computer-executable method, computer program product, and system for managing backups in a distributed data storage system including a first zone, a second zone, and a third zone, the computer-executable method, computer program product, and system comprising processing, at the third zone, a first portion of data of the first zone and a second portion of data of the second zone to create a combined portion of data, and removing the first portion and second portion from the third zone.

First claim

What is claimed is:

1. A computer-executable method of managing backups in a distributed data storage system including one or more zones which includes a first zone, a second zone, and a third zone, the computer-executable method comprising:
providing access to a first portion of data from the first zone, a second portion of data from the second zone, and a third portion of data from the third zone;
processing, at the third zone, the first portion of data of the first zone and the second portion of data of the second zone to create a combined portion of data, wherein the first zone, the second zone, and the third zone exist in separate locations, wherein each zone includes one or more data storage arrays;
wherein the first zone manages a primary backup of the first portion of data within the first zone and the second zone manages a primary backup of the second portion of data within the second zone; and
removing the first portion of data of the first zone and the second portion of data of the second zone from the third zone, to reduce an amount of backup data stored, wherein the processing comprises: executing an exclusive or (XOR) operation on the first portion of data of the first zone and the second portion of data of the second zone, wherein the combined portion of data is the first portion of data of the first zone XOR the second portion of data of the second zone.

2. The computer-executable method of claim 1 , further comprising:
receiving a request for the first portion of data, wherein a failure event has occurred at the first zone;
retrieving the second portion of data from the second zone; and
processing the second portion of data and the combined portion of data to restore the first portion of data.

3. The computer-executable method of claim 2 , wherein the failure event comprises losing an ability to communicate with the first zone.

4. The computer-executable method of claim 2 , further comprising responding to the request for the first portion of data.

5. The computer-executable method of claim 1 , wherein the first zone includes one or more compute nodes and one or more data storage arrays.

6. A system, comprising:
a distributed data storage system including one or more zones which includes a first zone, a second zone, and a third zone; and
computer-executable program logic encoded in memory of one or more computers in communication with the distributed data storage system to enable management of backups in the distributed data storage system, wherein the computer-executable program logic is configured for the execution of:
providing access to a first portion of data from the first zone, a second portion of data from the second zone, and a third portion of data from the third zone;
processing, at the third zone, the first portion of data of the first zone and the second portion of data of the second zone to create a combined portion of data, wherein the first zone, the second zone, and the third zone exist in separate locations, wherein each zone includes one or more data storage arrays;
wherein the first zone manages a primary backup of the first portion of data within the first zone and the second zone manages a primary backup of the second portion of data within the second zone; and
removing the first portion of data of the first zone and the second portion of data of the second zone from the third zone, to reduce an amount of backup data stored, wherein the processing comprises: executing an exclusive or (XOR) operation on the first portion of data of the first zone and the second portion of data of the second zone, wherein the combined portion of data is the first portion of data of the first zone XOR the second portion of data of the second zone.

7. The system of claim 6 , wherein the computer-executable program logic is further configured for the execution of:
receiving a request for the first portion of data, wherein a failure event has occurred at the first zone;
retrieving the second portion of data from the second zone; and
processing the second portion of data and the combined portion of data to restore the first portion of data.

8. The system of claim 7 , wherein the failure event comprises losing an ability to communicate with the first zone.

9. The system of claim 7 , wherein the computer-executable program logic is further configured for the execution of responding to the request for the first portion of data.

10. The system of claim 6 , wherein the first zone includes one or more compute nodes and one or more data storage arrays.

11. A non-transitory computer-readable storage medium, comprising
computer executable program code for managing backups in a distributed data storage system including one or more zones which includes a first zone, a second zone, and a third zone, the computer-executable program code configured to enable the execution of:
providing access to a first portion of data from the first zone, a second portion of data from the second zone, and a third portion of data from the third zone;
processing, at the third zone, the first portion of data of the first zone and the second portion of data of the second zone to create a combined portion of data, wherein the first zone, the second zone, and the third zone exist in separate locations, wherein each zone includes one or more data storage arrays;
wherein the first zone manages a primary backup of the first portion of data within the first zone and the second zone manages a primary backup of the second portion of data within the second zone; and
removing the first portion of data of the first zone and the second portion of data of the second zone from the third zone, to reduce an amount of backup data stored, wherein the processing comprises: executing an exclusive or (XOR) operation on the first portion of data of the first zone and the second portion of data of the second zone, wherein the combined portion of data is the first portion of data of the first zone XOR the second portion of data of the second zone.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the code is further configured to enable the execution of:
receiving a request for the first portion of data, wherein a failure event has occurred at the first zone;
retrieving the second portion of data from the second zone; and
processing the second portion of data and the combined portion of data to restore the first portion of data.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the failure event comprises losing an ability to communicate with the first zone.

14. The non-transitory computer-readable storage medium of claim 12 , wherein the code is further configured to enable the execution of responding to the request for the first portion of data.

15. The non-transitory computer-readable storage medium of claim 11 , wherein the first zone includes one or more compute nodes and one or more data storage arrays.
