System and method for providing direct host-based access to backup data
A method, computer program product, and computing system for receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system. A copy of the selected portion of the data may be generated on the backup storage appliance, thus defining a data backup copy. One or more hosts may be provided with direct access to the data backup copy using the storage system.
1. A computer-implemented method, executed on a computing device, comprising:
receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system;
generating a copy of the selected portion of the data on the backup storage appliance, thus defining a data backup copy accessible on the backup storage appliance; and
providing one or more hosts with direct access to the data backup copy on the backup storage appliance using the storage system without creating a new IO path directly between the one or more hosts and the backup storage appliance by generating a proxy volume associated with the data backup copy within the storage system and directing the one or more hosts to scan or rescan the storage system to detect the proxy volume to send one or more IO requests to the proxy volume.
2. The computer-implemented method of claim 1 , wherein receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system includes:
receiving a selection of a snapshot from the backup storage appliance.
3. The computer-implemented method of claim 1 , wherein providing one or more hosts with direct access to the data backup copy using the storage system includes:
processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance.
4. The computer-implemented method of claim 3 , wherein processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance includes:
processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance.
5. The computer-implemented method of claim 4 , wherein processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance includes:
receiving the one or more IO requests associated with the proxy volume within the storage system; and
redirecting the one or more IO requests associated with the proxy volume within the storage system for processing on the data backup copy on the backup storage appliance.
6. The computer-implemented method of claim 3 , further comprising:
copying data from the backup storage appliance to the storage system while processing the one or more IO requests from the storage system on the data backup copy on the backup storage appliance.
7. The computer-implemented method of claim 1 , further comprising:
receiving a request to discontinue the access to the data backup copy; and
deleting the data backup copy from the backup storage appliance.
8. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system;
generating a copy of the selected portion of the data on the backup storage appliance, thus defining a data backup copy accessible on the backup storage appliance; and
providing one or more hosts with direct access to the data backup copy on the backup storage appliance using the storage system without creating a new IO path directly between the one or more hosts and the backup storage appliance by generating a proxy volume associated with the data backup copy within the storage system and directing the one or more hosts to scan or rescan the storage system to detect the proxy volume to send one or more IO requests to the proxy volume.
9. The computer program product of claim 8 , wherein receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system includes:
receiving a selection of a snapshot from the backup storage appliance.
10. The computer program product of claim 8 , wherein providing one or more hosts with direct access to the data backup copy using the storage system includes:
processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance.
11. The computer program product of claim 10 , wherein processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance includes:
processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance.
12. The computer program product of claim 11 , wherein processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance includes:
receiving the one or more IO requests associated with the proxy volume within the storage system; and
redirecting the one or more IO requests associated with the proxy volume within the storage system for processing on the data backup copy on the backup storage appliance.
13. The computer program product of claim 10 , wherein the operations further comprise:
copying data from the backup storage appliance to the storage system while processing the one or more IO requests from the storage system on the data backup copy on the backup storage appliance.
14. The computer program product of claim 8 , wherein the operations further comprise:
receiving a request to discontinue the access to the data backup copy; and
deleting the data backup copy from the backup storage appliance.
15. A computing system comprising:
a memory; and
a processor configured to receive a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system, wherein the processor is further configured to generate a copy of the selected portion of the data on the backup storage appliance, thus defining a data backup copy accessible on the backup storage appliance, and wherein the processor is further configured to provide one or more hosts with direct access to the data backup copy on the backup storage appliance using the storage system without creating a new IO path directly between the one or more hosts and the backup storage appliance by generating a proxy volume associated with the data backup copy within the storage system and directing the one or more hosts to scan or rescan the storage system to detect the proxy volume to send one or more IO requests to the proxy volume.
16. The computing system of claim 15 , wherein receiving a selection of a portion of data from a backup storage appliance communicatively coupled to a storage system includes:
receiving a selection of a snapshot from the backup storage appliance.
17. The computing system of claim 15 , wherein providing one or more hosts with direct access to the data backup copy using the storage system includes:
processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance.
18. The computing system of claim 17 , wherein processing one or more IO requests from the storage system on the data backup copy on the backup storage appliance includes:
processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance.
19. The computing system of claim 18 , wherein processing one or more IO requests associated with the proxy volume on the data backup copy on the backup storage appliance includes:
receiving the one or more IO requests associated with the proxy volume within the storage system; and
redirecting the one or more IO requests associated with the proxy volume within the storage system for processing on the data backup copy on the backup storage appliance.
