General Requirements and Limitations

The following limitations apply to all storage systems supported by Veeam Backup & Replication.


Backup infrastructure for storage snapshots has the following requirements and limitations:

IPv6 Support

IPv6 is supported for the following storage systems:

If only management IPv6 connection is supported for a storage system, you can add this storage system to backup infrastructure using IPv6 address. However, all data traffic will be transferred over IPv4.


Temporary IPv6 addresses are not supported for backup infrastructure components and backed-up machines. For more information about using temporary addresses, see this RFC section.

To use IPv6 addresses and resolve names using IPv6, configure IPv6 communication as described in the IPv6 Support section in the Veeam Backup & Replication User Guide.

[VMware Integration] Backup from Storage Snapshots

Backup from storage snapshots has the following limitations:

[VMware Integration] Snapshot Orchestration and Backup from Storage Snapshots with Snapshot Retention

Snapshot jobs (snapshot-only jobs and backup jobs with storage snapshot retention) have the following requirements and limitations:

    • Enable HPE Web Services API server. Veeam Backup & Replication uses the HPE Web Services API server to work with the HPE Alletra/Primera storage system.
    • A license for the HPE Alletra/Primera storage system must support Virtual Copy.
    • You can use backup jobs to create a snapshot chain either on a primary or on a secondary storage array, but you cannot configure snapshot creation on both storage arrays at the same time.
  • For snapshot-only jobs:
    • If a VM added to the job has several disks that reside on the same volume, you cannot exclude specific VM disks from the backup as Veeam Backup & Replication creates snapshots at the volume level.
    • Veeam Backup & Replication does not support guest file indexing for snapshot-only jobs.
    • You cannot perform backup of VMs residing on a VMware datastore that comprises several extents (usually due to the use of several LUNs).

[VMware Integration] Data Recovery from Storage Snapshots

Data Recovery from Storage Snapshots has the following limitations:

  • You cannot restore files directly to the original location from backups of BSD, Mac and Solaris VMs. You cannot restore files directly to the original location from NSS filesystems. Use the Copy to option instead.
  • If the original VM is removed from vSphere infrastructure or migrated to another datastore, you will not be able to perform VM guest OS files restore to the original location.
  • [For HPE Alletra/Primera] Export types such as "Hosts and port" and "Port" are not supported. If you create such export types for a proxy or ESXi host, Veeam Backup & Replication will automatically create exports with the "Host" or "Host set" types instead.
