Veeam support statement for HPE Cloud Volumes Backup.
Veeam Backup & Replication v10 provides now official support for HPE Cloud Volumes Backup under the Veeam Experimental Support. For details on Experimental Support, see KB2976.
HPE Cloud Volumes Backup is a cloud-based backup service from HPE that emulates on-premises StoreOnce Catalyst Stores and can be used by Veeam Backup & Replication as a backup target that will automatically replicate to the HPE cloud. The HPE Cloud Volumes Backup Gateway Server can be added to Veeam Backup & Replication as a regular HPE StoreOnce Catalyst backup deduplication repository like any other Catalyst Store.
Considering possible bandwidth and latency constraints, Veeam recommends inline with the HPE guidelines the usage of HPE Cloud Volumes Backups as a secondary target repository, meaning that it is ideally used as a target for Backup Copy jobs with enabled HPE Catalyst Copy.
