摘要： An apparatus comprises at least one processing device configured to identify, utilizing virtualization software running on a storage system, a snapshot lineage comprising snapshots of a storage volume, the snapshot lineage comprising (i) a local snapshot lineage on the storage system and (ii) a cloud snapshot lineage on cloud storage external to the storage system. The processing device is also configured to utilize the virtualization software to select a given snapshot in the cloud snapshot lineage to recover to the local snapshot lineage, to expose a cloud storage volume for the given snapshot, and to map the cloud storage volume to a target local storage volume on the storage system. The processing device is further configured to recover the given snapshot to the local snapshot lineage by utilizing a data mover of the storage system to write data of the given snapshot to the target local storage volume.

摘要： An apparatus comprises at least one processing device configured to identify, utilizing virtualization software running on a storage system, a snapshot lineage comprising snapshots of a storage volume, the snapshot lineage comprising (i) a local snapshot lineage on storage devices of the storage system and (ii) a cloud snapshot lineage on cloud storage external to the storage system. The processing device is also configured to utilize the virtualization software to select a given snapshot in the local snapshot lineage to copy to the cloud snapshot lineage, to create a cloud storage volume on the cloud storage, and to map the cloud storage volume to the given snapshot in the local snapshot lineage. The processing device is further configured to copy the given snapshot to the cloud snapshot lineage by utilizing a data mover of the storage system to write data of the given snapshot to the cloud storage volume.

摘要： An apparatus comprises a processing device configured to identify a cloud snapshot lineage that is being managed by first virtualization software running on a first storage system, the cloud snapshot lineage comprising one or more snapshots of at least one storage volume, the cloud snapshot lineage being stored on cloud storage of at least one cloud external to the first storage system. The processing device is also configured to pause management of the cloud snapshot lineage by the first virtualization software running on the first storage system, to obtain, from the first virtualization software running on the first storage system, configuration data for the cloud snapshot lineage, to provide, to second virtualization software running on a second storage system, the configuration data for the cloud snapshot lineage, and to resume management of the cloud snapshot lineage by the second virtualization software running on the second storage system.
