Backup Copy Architecture

In this article

    To transport data from the source backup repository to the target backup repository, the backup copy job uses one of the following paths:

    Direct Transport Path

    Veeam Backup & Replication transports data directly from the source backup repository to the target backup repository. This type of data transport is recommended for copying backups to onsite backup repositories or offsite backup repositories over fast connections.

    When Veeam Backup & Replication transports data over the direct data path, it uses Veeam Data Movers on the following backup infrastructure components:

    If you have explicitly defined the gateway server, Veeam Backup & Replication will use the source Veeam Data Mover on the gateway server in the source site and target Veeam Data Mover on the gateway server on the target site.

    Transport Path over WAN Accelerators

    Veeam Backup & Replication transports data through a pair of WAN accelerators: one deployed on the source side and the other one deployed on the target side. WAN accelerators remove redundant blocks before transferring data and thus significantly reduce the amount of traffic going over the network. This type of data transport is recommended for copying backups offsite over slow connections or WAN.

    Important

    The WAN acceleration technology is included in the Veeam Universal License. When using a legacy socket-based license, the Enterprise Plus edition is required. For more information, see WAN Acceleration.

    When Veeam Backup & Replication transports data via WAN accelerators, it uses Veeam Data Movers on the following backup infrastructure components:

    I want to report a typo

    There is a misspelling right here:

     

    I want to let the Veeam Documentation Team know about that.
