Snapshot shipping to multiple cloud destinations

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device:

• to identify a snapshot lineage comprising one or more snapshots of a storage volume, the snapshot lineage comprising (i) a local snapshot lineage stored on at least one of one or more storage devices of a storage system and (ii) two or more cloud snapshot lineages stored on cloud storage external to the storage system;
• to select at least one snapshot that is to be copied from the local snapshot lineage;
• to determine at least two of the two or more cloud snapshot lineages as destinations for the selected at least one snapshot;
• to generate a snapshot copy job for copying the selected at least one snapshot to the at least two cloud snapshot lineages;
• and
• to process the snapshot copy job to copy the at least one snapshot from the local snapshot lineage to the at least two cloud snapshot lineages by reading data of the selected at least one snapshot stored in the local snapshot lineage once and writing the data of the selected at least one snapshot to the at least two cloud snapshot lineages;
• wherein writing of the data of the selected at least one snapshot to a first one of the at least two cloud snapshot lineages occurs at least in part in parallel with writing of the data of the selected at least one snapshot to a second one of the at least two cloud snapshot lineages.

A method comprising:

• identifying a snapshot lineage comprising one or more snapshots of a storage volume, the snapshot lineage comprising (i) a local snapshot lineage stored on at least one of one or more storage devices of a storage system and (ii) two or more cloud snapshot lineages stored on cloud storage external to the storage system;
• selecting at least one snapshot that is to be copied from the local snapshot lineage;
• determining at least two of the two or more cloud snapshot lineages as destinations for the selected at least one snapshot;
• generating a snapshot copy job for copying the selected at least one snapshot to the at least two cloud snapshot lineages;
• and
• processing the snapshot copy job to copy the at least one snapshot from the local snapshot lineage to the at least two cloud snapshot lineages by reading data of the selected at least one snapshot stored in the local snapshot lineage once and writing the data of the selected at least one snapshot to the at least two cloud snapshot lineages;
• wherein writing of the data of the selected at least one snapshot to a first one of the at least two cloud snapshot lineages occurs at least in part in parallel with writing of the data of the selected at least one snapshot to a second one of the at least two cloud snapshot lineages;
• and
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
