System and method for high priority backup
View Patent ↗A coordination point for assigning clients to remote backup storages includes a persistent storage and a processor. The persistent storage stores gateway pool cache capacities of the remote backup storages. The processor obtains a data storage request for data from a client of the clients; obtains an indirect cache estimate for servicing the data storage request; selects a remote backup storage of the remote backup storages based on the obtained indirect cache estimate using the gateway pool cache capacities; and assign the selected remote backup storage to service the data storage request. The selected remote backup storage has a higher client load at a time selection than a second client load of a second remote backup storage of the remote backup storages.
1. A coordination point for assigning clients to remote backup storages, comprising:
a persistent storage storing gateway pool cache capacities of the remote backup storages; and
a processor programmed to:
obtain a data storage request for data from a client of the clients;
obtain an indirect cache estimate for servicing the data storage request;
select a remote backup storage of the remote backup storages based on the obtained indirect cache estimate using the gateway pool cache capacities; and
assign the selected remote backup storage to service the data storage request,
wherein the selected remote backup storage has a higher client load at a time of the selection of the remote backup storage than a second client load of a second remote backup storage of the remote backup storages.
2. The coordination point of claim 1 , wherein the processor is further programmed to:
obtain a second data storage request for second data from a second client of the clients;
obtain a second indirect cache estimate for servicing the second data storage request;
make a determination that none of the remote backup storages have sufficient cache based on the obtained second indirect cache estimate using the gateway pool cache capacities;
in response to the determination:
assign a gateway to a third remote data storage;
select the third remote backup storage after assigning the gateway; and
assign the selected third remote backup storage to service the second data storage request.
3. The coordination point of claim 2 , wherein assigning the gateway to the third remote data storage comprises:
selecting an unassigned gateway; and
distributing a portion of a distributed cache of the third remote data storage across a cache of the unassigned gateway.
4. The coordination point of claim 2 , wherein assigning the gateway to the third remote data storage comprises:
selecting an assigned gateway of a fourth remote data storage;
removing a portion of a distributed cache of the fourth remote data storage from a cache of the selected assigned gateway; and
distributing a portion of a distributed cache of the third remote data storage across the cache of the assigned gateway.
5. The coordination point of claim 1 , wherein the processor is further programmed to:
obtain a notification from the selected remote backup storage that the obtained indirect cache estimate underestimated an actual cache use by the client;
in response to the notification:
assign a gateway to the selected remote backup storage; and
distribute a portion of a distributed cache of the selected remote data storage across a cache of the gateway.
6. The coordination point of claim 5 , wherein the gateway was assigned to a third remote data storage before being assigned to the selected remote data storage.
7. The coordination point of claim 1 , wherein the gateway pool cache capacities specifies cache capacities of distributed caches of the remote data storages.
8. The coordination point of claim 7 , wherein each respective distributed cache is hosted by a plurality of gateways of a respective remote data storage of the remote data storages.
9. The coordination point of claim 1 , wherein obtaining the indirect cache estimate for servicing the data storage request comprises:
identifying a type of application generating the data.
10. The coordination point of claim 9 , wherein obtaining the indirect cache estimate for servicing the data storage request further comprises:
identifying a transaction rate of the identified type of application generating the data.
11. The coordination point of claim 1 , wherein obtaining the indirect cache estimate for servicing the data storage request comprises:
identifying a computing resource capacity of the client.
12. The coordination point of claim 1 , wherein obtaining the indirect cache estimate for servicing the data storage request comprises:
identifying an average available bandwidth between the client and the remote backup storages.
13. The coordination point of claim 1 , wherein selecting the remote backup storage of the remote backup storages based on the obtained indirect cache estimate using the gateway pool cache capacities comprises:
identifying a portion of the remote backup storages that have an available cache capacity that is larger than the obtained indirect cache estimate.
14. The coordination point of claim 13 , wherein selecting the remote backup storage of the remote backup storages based on the obtained indirect cache estimate using the gateway pool cache capacities further comprises:
identifying a remote backup storage of the portion of the remote backup storages that has a smallest client load; and
using the identified remote backup storage of the portion of the remote backup storages as the selected remote backup storage.
15. The coordination point of claim 1 , wherein the client load of the selected remote backup storage is a cardinality of a number of clients assigned to the selected remote backup storage.
16. The coordination point of claim 1 , wherein the client load of the selected remote backup storage is a quantity of computing resources utilized by a number of the clients assigned to the selected remote backup storage.
17. A method of operating a coordination point for assigning clients to remote backup storages, comprising:
obtaining a data storage request for data from a client of the clients;
obtaining an indirect cache estimate for servicing the data storage request;
selecting a remote backup storage of the remote backup storages based on the obtained indirect cache estimate using gateway pool cache capacities of the remote backup storages; and
assigning the selected remote backup storage to service the data storage request,
wherein the selected remote backup storage has a higher client load at a time of the selection of the remote backup storage than a second client load of a second remote backup storage of the remote backup storages.
18. The method of claim 17 , further comprising:
obtaining a second data storage request for second data from a second client of the clients;
obtaining a second indirect cache estimate for servicing the second data storage request;
making a determination that none of the remote backup storages have sufficient cache based on the obtained second indirect cache estimate using the gateway pool cache capacities;
in response to the determination:
assign a gateway to a third remote data storage;
selecting the third remote backup storage after assigning the gateway; and
assigning the selected third remote backup storage to service the second data storage request.
19. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for assigning clients to remote backup storages, the method comprising:
obtaining a data storage request for data from a client of the clients;
obtaining an indirect cache estimate for servicing the data storage request;
selecting a remote backup storage of the remote backup storages based on the obtained indirect cache estimate using gateway pool cache capacities of the remote backup storages; and
assigning the selected remote backup storage to service the data storage request,
wherein the selected remote backup storage has a higher client load at a time of the selection of the remote backup storage than a second client load of a second remote backup storage of the remote backup storages.
20. The non-transitory computer readable medium of claim 19 , wherein the method further comprises:
obtaining a second data storage request for second data from a second client of the clients;
