Storage Snapshots in Secondary Destination Jobs

You can configure a backup job to create regular backup files on the backup repository and, additionally, maintain a snapshot chain on the storage system. Veeam Backup & Replication lets you create storage snapshots in the following destinations:

  • Primary storage array where VM disks are hosted
  • Secondary storage arrays

Storage Snapshots in Secondary Destination Jobs Note:

[For IBM Spectrum Virtualize] When you add IBM Spectrum Virtualize storage systems with HyperSwap function to the backup infrastructure, Veeam Backup and Replication, by default, works with primary storage volumes. If you want to select secondary storage volumes as a data source for backup, use registry keys. For more information, contact Veeam Support Team.

Depending on the backup job settings, the created storage snapshots can be application-consistent or crash-consistent.

The backup job of this type is performed in the following way:

  1. Veeam Backup & Replication triggers VMware vCenter Server to create a VMware vSphere snapshot for a VM.
  2. Veeam Backup & Replication instructs the storage system to create two snapshots of a volume or LUN capturing VM disks:
    • A new snapshot on the storage system. This snapshot remains in the snapshot chain until it is removed by the retention policy.
    • A temporary snapshot for backup or replication operations. This snapshot is removed after backup or replication is complete.
  1. Veeam Backup & Replication removes the created VMware vSphere snapshot from the VM snapshot list.
  2. Veeam Backup & Replication uses the temporary storage snapshot as a data source for backup and replication.
  3. Veeam Backup & Replication performs cleanup operations and removes the temporary snapshot on the storage array.
  4. Veeam Backup & Replication checks the number of storage snapshots in the snapshot chain. If the number exceeds the value defined in retention policy settings, Veeam Backup & Replication instructs the storage system to remove the earliest snapshot from the snapshot chain.
