Veeam Data Movers

In this article

    Veeam Data Mover performs data processing tasks on behalf of Veeam Backup & Replication, such as retrieving source machine data, performing data deduplication and compression, and storing backed-up data on the target storage.

    For Microsoft Windows servers, Veeam Data Movers are persistent, that is, Veeam Data Mover is uploaded and installed on a server only once. Veeam Backup & Replication automatically installs Veeam Data Mover when you add a Microsoft Windows server to the backup infrastructure.

    For Linux servers, Veeam Data Movers can be persistent or non-persistent. Non-persistent Veeam Data Mover is uploaded and removed each time Veeam Backup & Replication addresses a server.

    For Veeam Data Mover to be persistent, you must specify an account with root or equivalent to root permissions when adding a Linux server. Persistent Veeam Data Movers are required for hardened repositories.

    For other backup infrastructure components based on Linux servers, Veeam Data Movers can be persistent or non-persistent. If you do not want to provide root or equivalent to root permissions, specify an account with non-root permissions. In this case, Veeam Data Movers will be non-persistent. Veeam Backup & Replication will upload and start Veeam Data Movers through the SSH connection when Veeam Backup & Replication addresses the server. 

    Requirements and Limitations for Veeam Data Movers

    Before you use Veeam Data Movers, consider the following requirements and limitations for Linux and Microsoft Windows servers:

    • Linux server version must be 64-bit. For more information, see System Requirements. Note that Perl is required only for non-persistent Veeam Data Movers. Check the full list of required Perl modules in this Veeam KB article.
    • Veeam Backup & Replication does not deploy Veeam Data Movers on deduplicating storage appliances based on Linux.
    • If you want to use persistent Veeam Data Movers, the user account specified for the server must have root or elevated to root permission. Otherwise, Veeam Data Movers will be non-persistent, that is, the Linux server will not host Veeam Data Movers permanently.
    • When you add a Linux server using single-use credentials, the user account must still have elevated to root permission in order for Veeam Data Movers to be persistent.
    • For Microsoft Hyper-V and Microsoft Windows servers: file and printer sharing must be enabled in network connection settings of the added server.

    Tip

    If Veeam Data Mover on a Linux server fails for some reason, you can re-install it manually. For more information, see this Veeam KB article.
