US 2019/0163382 A1 · ENABLING DATA INTEGRITY CHECKING AND FASTER APPLICATION RECOVERY IN SYNCHRONOUS REPLICATED DATASETS

Abstract

One or more techniques and/or computing devices are provided for utilizing snapshots for data integrity validation and/or faster application recovery. For example, a first storage controller, hosting first storage, has a synchronous replication relationship with a second storage controller hosting second storage. A snapshot replication policy rule is defined to specify that a replication label is to be used for snapshot create requests, targeting the first storage, that are to be replicated to the second storage. A snapshot creation policy is created to issue snapshot create requests comprising the replication label. Thus a snapshot of the first storage and a replication snapshot of the second storage are created based upon a snapshot create request comprising the replication label. The snapshot and the replication snapshot may be compared for data integrity validation (e.g., determine whether the snapshots comprise the same data) and/or quickly recovering an application after a disaster.

Claims20

Dependent claims

A method comprising:

creating a snapshot of first storage at a first node having a synchronous replication relationship with a second node hosting second storage based upon a snapshot create request;
creating a replication snapshot of the second storage at the second node based upon the snapshot create request;
and
utilizing the replication snapshot to recover an application to utilize the second storage in place of the first storage.

1 more element

A non-transitory machine readable medium having stored thereon machine executable code which when executed by a machine, causes the machine to:

create a snapshot of first storage at a first node having a synchronous replication relationship with a second node hosting second storage based upon a snapshot create request;
create a replication snapshot of the second storage at the second node based upon the snapshot create request;
and
utilize the replication snapshot to recover an application to utilize the second storage in place of the first storage.
