System and method for prioritizing replication copy activity
A method, computer program product, and computer system for triggering, by a computing device, a synchronization activity on a storage object. A request may be executed for a copy operation resulting from the synchronization activity to copy the storage object from a source to a destination when a current number of concurrent copy operations is below a maximum number of copy operations. The request for the copy operation resulting from the synchronization activity to copy the storage object from the source to the destination may be placed in a queue when the current number of concurrent copy operations is at least at the maximum number of copy operations. One or more attributes of the request in the queue may be identified. The request for the copy operation may be executed according to a replication policy based upon, at least in part, the one or more attributes of the request in the queue.
1. A computer-implemented method comprising:
triggering, by a computing device, a synchronization activity on a storage object wherein the synchronization activity is triggered when a current time equals a sum of a last synchronization time for the storage object plus a percentage of a value corresponding to an amount of acceptable data loss;
executing a request for a copy operation resulting from the synchronization activity to copy the storage object from a source to a destination when a current number of concurrent copy operations is below a maximum number of copy operations;
placing in a queue the request for the copy operation resulting from the synchronization activity to copy the storage object from the source to the destination when the current number of concurrent copy operations is at least at the maximum number of copy operations;
identifying one or more attributes of the request in the queue; and
executing the request for the copy operation according to a replication policy based upon, at least in part, the one or more attributes of the request in the queue.
2. The computer-implemented method of claim 1 wherein the one or more attributes of the request in the queue includes at least one of an identification of the storage object, a time-to-Recovery-Point-Objective-violation of the storage object, a time-to-alert for the storage object, and a generation time of the copy request.
3. The computer-implemented method of claim 2 wherein the replication policy prioritizes the copy request for execution from the queue according to a plurality of rules.
4. The computer-implemented method of claim 3 wherein a first rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in an alerted state with an oldest time-to-alert value.
5. The computer-implemented method of claim 4 wherein a second rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in a Recovery Point Objective alerted state with an oldest time-to-Recovery-Point-Objective-violation value, wherein the first rule has a higher priority than the second rule.
6. The computer-implemented method of claim 5 wherein a third rule of the plurality of rules includes prioritizing execution of the copy request based upon an oldest request generation time when both the copy request and another copy request match one of the first and second rule, wherein the second rule has a higher priority than the third rule.
7. A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, causes at least a portion of the one or more processors to perform operations comprising:
triggering a synchronization activity on a storage object, wherein the synchronization activity is triggered when a current time equals a sum of a last synchronization time for the storage object plus a percentage of a value corresponding to an amount of acceptable data loss;
executing a request for a copy operation resulting from the synchronization activity to copy the storage object from a source to a destination when a current number of concurrent copy operations is below a maximum number of copy operations;
placing in a queue the request for the copy operation resulting from the synchronization activity to copy the storage object from the source to the destination when the current number of concurrent copy operations is at least at the maximum number of copy operations;
identifying one or more attributes of the request in the queue; and
executing the request for the copy operation according to a replication policy based upon, at least in part, the one or more attributes of the request in the queue.
8. The computer program product of claim 7 wherein the one or more attributes of the request in the queue includes at least one of an identification of the storage object, a time-to-Recovery-Point-Objective-violation of the storage object, a time-to-alert for the storage object, and a generation time of the copy request.
9. The computer program product of claim 8 wherein the replication policy prioritizes the copy request for execution from the queue according to a plurality of rules.
10. The computer program product of claim 9 wherein a first rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in an alerted state with an oldest time-to-alert value.
11. The computer program product of claim 10 wherein a second rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in a Recovery Point Objective alerted state with an oldest time-to-Recovery-Point-Objective-violation value, wherein the first rule has a higher priority than the second rule.
12. The computer program product of claim 11 wherein a third rule of the plurality of rules includes prioritizing execution of the copy request based upon an oldest request generation time when both the copy request and another copy request match one of the first and second rule, wherein the second rule has a higher priority than the third rule.
13. A computing system including one or more processors and one or more memories configured to perform operations comprising:
triggering a synchronization activity on a storage object, wherein the synchronization activity is triggered when a current time equals a sum of a last synchronization time for the storage object plus a percentage of a value corresponding to an amount of acceptable data loss;
executing a request for a copy operation resulting from the synchronization activity to copy the storage object from a source to a destination when a current number of concurrent copy operations is below a maximum number of copy operations;
placing in a queue the request for the copy operation resulting from the synchronization activity to copy the storage object from the source to the destination when the current number of concurrent copy operations is at least at the maximum number of copy operations;
identifying one or more attributes of the request in the queue; and
executing the request for the copy operation according to a replication policy based upon, at least in part, the one or more attributes of the request in the queue.
14. The computing system of claim 13 wherein the one or more attributes of the request in the queue includes at least one of an identification of the storage object, a time-to-Recovery-Point-Objective-violation of the storage object, a time-to-alert for the storage object, and a generation time of the copy request.
15. The computing system of claim 14 wherein the replication policy prioritizes the copy request for execution from the queue according to a plurality of rules.
16. The computing system of claim 15 wherein a first rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in an alerted state with an oldest time-to-alert value.
17. The computing system of claim 16 wherein a second rule of the plurality of rules includes prioritizing execution of the copy request when the copy request is in a Recovery Point Objective alerted state with an oldest time-to-Recovery-Point-Objective-violation value, wherein the first rule has a higher priority than the second rule, and wherein a third rule of the plurality of rules includes prioritizing execution of the copy request based upon an oldest request generation time when both the copy request and another copy request match one of the first and second rule, wherein the second rule has a higher priority than the third rule.
