Data protection and incremental processing for multi-span business applications
A protection orchestrator manages creation of temporally consistent protection points for a multi-span business application. Each multi-span protection point includes component protection points generated by nodes such as host computers, storage arrays, version control repositories and cloud storage gateways. Shim programs running on the nodes translate commands from the protection orchestrator into protocol commands for the node with which they are associated. A first command pauses changes to all components of the multi-span business application. A second command causes creation of the component protection points. A third command un-pauses the changes to the components.
1. An apparatus comprising:
a storage array comprising:
a plurality of interconnected computing nodes, each of the computing nodes comprising at least one processor and non-transitory volatile memory;
a plurality of groups of non-volatile data storage drives, each group of data storage drives connected with one of the computing nodes;
a plurality of host computers, each host computer running at least one component program of a plurality of component programs that comprise a multi-span business application, component program data being stored on the storage array; and
a protection orchestrator comprising instructions stored on non-transitory computer-readable memory that:
causes changes to the component programs and the data to pause;
causes creation of temporally consistent component protection points for the component programs and the data; and
causes changes to the component programs and the data to un-pause after creating the temporally consistent component protection points.
2. The apparatus of claim 1 comprising a first shim program running on a first one of the host computers, the first shim program translating a first command to create a component protection point into a first protocol message that is supported by the first host computer.
3. The apparatus of claim 2 comprising a second shim program running on a second one of the host computers, the second shim program translating the first command into a second protocol message that is supported by the second host computer, the first protocol message being different than the first protocol message.
4. The apparatus of claim 3 comprising a third shim program running on a storage array, the third shim program translating the first command into a third protocol message that is supported by the storage array, the first, second and third protocol messages being different from each other.
5. The apparatus of claim 4 comprising a fourth shim program running on a version control repository, the fourth shim program translating the first command into a fourth protocol message that is supported by the version control repository, the first, second, third and fourth protocol messages being different from each other.
6. The apparatus of claim 1 wherein each of the component protection points is a snap.
7. The apparatus of claim 1 wherein each of the component protection points is a clone.
8. The apparatus of claim 1 wherein each of the component protection points is a backup.
9. The apparatus of claim 1 wherein each of the component protection points is an incremental backup.
10. The apparatus of claim 1 comprising a data replication appliance on which the protection orchestrator runs.
11. A method comprising:
in a network comprising:
a storage array comprising:
a plurality of interconnected computing nodes, each of the computing nodes comprising at least one processor and non-transitory volatile memory;
a plurality of groups of non-volatile data storage drives, each group of data storage drives connected with one of the computing nodes; and
a plurality of host computers, each host computer running at least one component program of a plurality of component programs that comprise a multi-span business application, component program data being stored on the storage array;
pausing changes to the component programs and the data;
creating temporally consistent component protection points for the component programs and the data; and
un-pausing changes to the component programs and the data after creating the temporally consistent component protection points.
12. The method of claim 11 comprising running a first shim program on a first one of the host computers, the first shim program translating a first command to create a component protection point into a first protocol message that is supported by the first host computer.
13. The method of claim 12 comprising running a second shim program on a second one of the host computers, the second shim program translating the first command into a second protocol message that is supported by the second host computer, the first protocol message being different than the first protocol message.
14. The method of claim 13 comprising running a third shim program on a storage array, the third shim program translating the first command into a third protocol message that is supported by the storage array, the first, second and third protocol messages being different from each other.
15. The method of claim 14 comprising running a fourth shim program on a version control repository, the fourth shim program translating the first command into a fourth protocol message that is supported by the version control repository, the first, second, third and fourth protocol messages being different from each other.
16. The method of claim 11 wherein creating temporally consistent component protection points comprises creating snaps.
17. The method of claim 11 wherein creating temporally consistent component protection points comprises creating clones.
18. The method of claim 11 wherein creating temporally consistent component protection points comprises creating backups.
19. The method of claim 11 wherein creating temporally consistent component protection points comprises creating incremental backups.
20. The method of claim 15 comprising sending the command from a protection orchestrator running on a data replication appliance.
