Abstract

A system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations comprising attaching a protection policy associated with a rule to a storage object, wherein the rule can be applicable to prevent redundant snapshot creation. The operations can further comprise, in response to the attaching of the protection policy to the storage object, triggering creation of a first snapshot and a second snapshot of the storage object. The operations can further comprise detecting any uniquely allocated storage regions between the first snapshot and the second snapshot. The operations can further comprise, based on a determination of whether any extra bits of the any uniquely allocated storage regions are unallocated or zeroed out, determining whether to prevent a third creation of a third snapshot external to the first snapshot and the second snapshot.

Claims20

Dependent claims

A system, comprising:

a processor;
and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
attaching, by a policy manager of the system, a protection policy associated with a rule to a storage object, wherein the rule is applicable to prevent redundant snapshot creation;
in response to the attaching of the protection policy to the storage object, triggering, by the policy manager, a first creation of a first snapshot of the storage object, and triggering, by the policy manager, a second creation of a second snapshot from the first snapshot, wherein the first snapshot and the second snapshot comprise identical snapshot information;
refreshing, using a snap engine control path process, the first snapshot to capture a difference between a current state of the storage object and a prior state of the storage object, wherein the first snapshot reflects the current state of the storage object and the second snapshot reflects the prior state of the storage object;
detecting, by a core logical engine of the system, based on the difference, uniquely allocated storage regions between the first snapshot and the second snapshot;
and
based on a determination of whether any extra bits of the uniquely allocated storage regions exist, determining whether to prevent a third creation of a third snapshot, wherein the third snapshot is external to the first snapshot and the second snapshot.

A method, comprising:

attaching, by a system comprising a processor, a protection policy associated with a rule to a storage object, wherein the rule is applicable to prevent redundant snapshot creation;
in response to the attaching of the protection policy to the storage object, triggering, by the system, a first creation of a first snapshot of the storage object, and triggering a second creation of a second snapshot from the first snapshot, wherein the first snapshot and the second snapshot comprise identical snapshot information;
refreshing, by the system, the second snapshot to capture a difference between a current state of the storage object and a prior state of the storage object, wherein the second snapshot reflects the current state of the storage object and the first snapshot reflects the prior state of the storage object;
detecting, by the system, based on the difference, uniquely allocated storage regions between the first snapshot and the second snapshot;
and
based on a determination of whether any extra bits of the uniquely allocated storage regions exist, determining, by the system, whether to prevent a third creation of a third snapshot external to the first snapshot and the second snapshot, wherein the third snapshot is reflected via a user device.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, the operations comprising:

attaching a protection policy associated with a rule to a storage object, wherein the rule is applicable to prevent redundant snapshot creation;
in response to the attaching of the protection policy to the storage object, initiating a first creation of a first snapshot of the storage object, and initiating a second creation of a second snapshot from the first snapshot, wherein the first snapshot and the second snapshot comprise identical snapshot information;
alternately refreshing the first snapshot and the second snapshot to capture a difference between a current state of the storage object and a prior state of the storage object;
detecting, based on the difference, uniquely allocated storage regions between the first snapshot and the second snapshot;
and
based on a determination of whether any extra bits of the uniquely allocated storage regions exist, determining whether to create a third snapshot of the storage object.
