Data Transport Path

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 VM data over the direct data path, it uses Veeam Data Mover Services on the following backup infrastructure components:

• In case of Microsoft Windows and Linux repositories: Veeam Backup & Replication uses the source Veeam Data Mover Service on the source backup repository and target Veeam Data Mover Service on the target backup repository.

• In case of CIFS share: if you have instructed Veeam Backup & Replication to automatically select the gateway server, Veeam Backup & Replication will use the Data Mover Services deployed on the backup server. If you have explicitly defined the gateway server, Veeam Backup & Replication will use the source Veeam Data Mover Service on the gateway server in the source site and target Veeam Data Mover Service on the gateway server on the target site.

• Through built-in 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 VM 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.

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

• In case of Microsoft Windows and Linux repositories: Veeam Backup & Replication uses the source Veeam Data Mover Service on the source backup repository and target Veeam Data Mover Service on the target backup repository.

• In case of CIFS share: if you have instructed Veeam Backup & Replication to automatically select the gateway server, Veeam Backup & Replication will use the Data Mover Services deployed on the source and/or target WAN accelerator. If you have explicitly defined the gateway server, Veeam Backup & Replication will use the source Veeam Data Mover Service on the gateway server in the source site and target Veeam Data Mover Service on the gateway server on the target site.
