Backup Copy Architecture

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:

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.

The WAN acceleration technology is available in the Enterprise Plus Edition of Veeam Backup & Replication. 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:
