How do I backup my VMs on Scale HC3?



  • A: There are several options available to HC3 users, including the native HC3 backup capabilities.

    HC3 features a full set of native features to allow users to backup, replicate, failover, restore, and recover virtual machines. Snapshot-based, incremental backups can be performed between HC3 systems without any additional software or licensing. Many HC3 users implement a second HC3 cluster or a single node to serve as a backup location or failover site. The backup location can be as second HC3 system that is onsite or remote. The backup location can be used just to store backups, or to fail them over if the primary HC3 system fails. HC3 VM backups can be restored to the primary HC3 system sending only the data that is different. Backup scheduling and retention can be configured granularly for each VM to meet SLAs.

    Scale Computing also offers the ScaleCare Remote Recovery Service as a cloud-based backup for HC3 systems supporting all of the native HC3 features. For users who lack a secondary backup site, the remote recovery service acts as a backup site for any VMs that need protection. VMs can be recovered instantly on remote recovery platform to run in production until they can be restored back to the primary site. The Remote Recovery Service also includes a runbook to assist in DR planning and execution from implementation to recovery. ScaleCare engineers assist in the Remote Recovery Service in planning, implementation, DR testing, and recovery.

    HC3 VMs can also be backed up using virtually any third-party backup software that supports your guest operating system and applications. If you are migrating an existing physical machine to a VM, you likely don’t need to change your backup at all. Backup solutions, including Veeam, that include backup agents can be used with the guest operating system allowing them to be backed up over the network to a backup server or other location depending on the solution. (other popular ones we see and in some cases have tested include Unitrends, Acronis, Storagecraft, Barracuda)

    Some HC3 users choose to use HC3 native export features to export VM snapshots or backups to store on third party backup servers or storage. This extra backup method can be useful for long-term storage of VM backups. These exported backups can be imported into any other HC3 system for recovery. (Note - while exports currently can't be scheduled in the UI, they can be done of live machines at any time and the ScaleCare support team may be able to set up a simple scheduling process for these "under the hood" ... contact support to discuss)
