Abstract

Write IO operations on a set of storage volumes of a storage volume group are monitored, and one or more activity-based snapshot creation write IO thresholds are used to identify triggering events to create snapshots of the set of storage volumes. Activity-based snapshot creation write IO thresholds may be based on a total number of write IO operations that must occur on the set of storage volumes prior to creation of a snapset, on an average number of write IO operations that must occur on the set of storage volumes prior to creation of a snapset, a minimum number of write IO operations that must occur on each of the storage volumes prior to creation of a snapset, a maximum number of write IO operations that may occur on any one of the storage volumes prior to creation of a snapset, or a combination of write IO thresholds.

Claims18

Dependent claims

A non-transitory tangible computer-readable storage medium storing software for activity-based snapshot creation, the software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

defining a storage volume monitoring group, the storage volume monitoring group including a set of two or more storage volumes;
setting a snapset creation write IO threshold for the storage volume monitoring group, the snapset creation write IO threshold specifying a write IO activity parameter for the storage volume monitoring group such that satisfying the write IO activity parameter results in creation of a snapset of the storage volume monitoring group, the snapset including a respective snapshot of each storage volume of the set of two or more storage volumes of the storage volume monitoring group;
monitoring write IO operations on the set of storage volumes of the storage volume monitoring group;
comparing the monitored write IO operations with the snapset creation write IO threshold;
and
in response to a determination that the monitored IO operations on the set of storage volumes of the storage volume monitoring group satisfy the write IO activity parameter, causing the creation of the snapset;
wherein causing the creation of the snapset comprises creating the respective snapshot of each storage volume of the set of two or more storage volumes of the storage volume monitoring group.

4 more elements

A system for activity-based snapshot creation, comprising:

one or more processors and one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations comprising:
defining a storage volume monitoring group, the storage volume monitoring group including a set of two or more storage volumes;
setting a snapset creation write IO threshold for the storage volume monitoring group, the snapset creation write IO threshold specifying a write IO activity parameter for the storage volume monitoring group such that satisfying the write IO activity parameter results in creation of a snapset of the storage volume monitoring group, the snapset including a respective snapshot of each storage volume of the set of two or more storage volumes of the storage volume monitoring group;
monitoring write IO operations on the set of storage volumes of the storage volume monitoring group;
comparing the monitored write IO operations with the snapset creation write IO threshold;
and
in response to a determination that the monitored IO operations on the set of storage volumes of the storage volume monitoring group satisfy the write IO activity parameter, causing the creation of the snapset;
wherein causing the creation of the snapset comprises creating the respective snapshot of each storage volume of the set of two or more storage volumes of the storage volume monitoring group.
