Limitations and Considerations

In this article

    When you plan to deploy Veeam Backup for Microsoft Azure and set up the backup infrastructure, keep in mind the following limitations and considerations.

    Hardware

    Component

    Recommended Azure VM size

    Backup appliance

    • Standard_B2s with 2 CPUs and 4 GB RAM
    • Standard_B2ms with 2 CPUs and 4 GB RAM

    Workers

    • Standard_F2s_v2 with 2 CPUs and 4 GB RAM for standard backup
    • Standard_E2_v4 with 2 CPUs and 16 GB RAM for archived backup

    For more information on Azure VM sizes, see Microsoft Docs.

    Software

    Internet Explorer is not supported. To access Veeam Backup for Microsoft Azure, use Microsoft Edge (latest version), Mozilla Firefox (latest version) or Google Chrome (latest version).

    Network Settings for Worker Instances

    Before you start adding worker configurations, consider the following:

    • A service endpoint (routing) for the Microsoft.Storage service must be configured for virtual networks to which workers will be connected. To learn how to configure virtual network service endpoints, see Microsoft Docs.
    • A subnet to which workers will be connected must have at least one free IP address in the subnet range — Veeam Backup for Microsoft Azure will deploy and simultaneously run as many worker instances as many free IP addresses there are in the subnet range.

    For more information on worker configurations, see Configuring Workers.

    Encryption

    Azure Disk Encryption is not supported in the current Veeam Backup for Microsoft Azure version. Veeam Backup for Microsoft Azure will not be able to perform file-level recovery for VMs whose virtual disks are encrypted using Azure Disk Encryption. For more information on Azure Disk Encryption, see Microsoft Docs.

    Backup

    Before you start protecting Azure resources, consider the following:

    • Veeam Backup for Microsoft Azure does not support archive tiering for storage accounts with enabled blob soft delete and data redundancy (ZRS, GZRS, RA-GZRS) options.
    • When Veeam Backup for Microsoft Azure backs up Azure VMs with IPv6 addresses assigned, it does not store the addresses. That is why if you plan to restore these VMs, keep in mind that you will have to assign IPv6 addresses to the restored VMs manually on the Microsoft Azure portal, after the restore process completes.

    Security Certificates

    Veeam Backup for Microsoft Azure supports certificates only in the .PFX format.
