Abstract: A computer implemented method includes maintaining information indicative of whether a data replication relationship between a dataset associated with the local CG and a mirror copy of the dataset stored on a remote CG of a remote distributed storage system is in an in-synchronization (InSync) state or an out-of-synchronization (OOS) state, initiating a storage expansion process including a source expansion to create a new source volume as a member of the local CG and a destination expansion to create a new destination volume as a member of the remote CG, and initiating a data replication relationship expand to establish a data replication relationship for the new source volume and the new destination volume.

Abstract: Systems and methods are described for performing an instant recovery of data associated with a locked snapshot. In various examples, the amount of time for performing a recovery of data associated with a locked snapshot is significantly reduced by making use of enhanced volume cloning functionality instead of making an actual copy of the data to be recovered. In one embodiment, the resulting volume clone representing the recovery volume is cleared of all data protection information (e.g., WORM flags and/or lock metafiles) that was previously used to protect the content from being changed when stored on the data protection volume so as allow the recovery volume to be used in read-write mode.

Abstract: A computer implemented method includes maintaining information indicative of whether a data replication relationship between a dataset associated with the local CG (CG1) and a mirror copy of the dataset stored on a remote CG (CG2) of a remote distributed storage system is in an in-synchronization (InSync) state or an out-of-synchronization (OOS) state, determining whether a CG storage expansion process is in progress, and in response to determining the OOS state and whether the primary storage site has a failure, initiating an automatic unplanned failover (AUFO) workflow without manual intervention on the original volumes in the CG1 of a first storage cluster of the primary storage site and the original volumes in the CG2 of a second storage cluster when the CG storage expansion process is in progress with a new source volume to be a member of CG1 and a new destination volume to be a member of CG2.
