Parallel Processing

Veeam Backup & Replication 7.0 introduces parallel processing: each VM (in case of a single virtual disk) or each VM disk (in case of multiple disks) is assigned a data processing task. Tasks within a single job can be processed simultaneously, optimizing your backup infrastructure performance and increasing the efficiency of resource usage.


In versions of Veeam Backup & Replication prior to 7.0 each backup or replication job used to process only a single VM at a time, so that multiple VMs included in a job were processed sequentially in order. To take full advantage of all proxy resources and to scale out, users configured multiple jobs, and these jobs would then be automatically balanced among the available proxy resources.

To use this parallel processing capability, proxy server(s) should meet system requirements — each task requires a single CPU core, so for two tasks to be processed in parallel, 2 cores is the recommended minimum; also, parallel VM processing should be enabled on the Advanced tab in Veeam Backup & Replication options:



If Virtual Appliance transport mode is used, parallel processing will process all the disks that it is able to but this will be limited to only 1 disk per proxy at a time. In this mode Veeam will be unable to process multiple disks on the same proxy. This refers to both backup and replication jobs.

Backup copy jobs do not support parallel processing. Multiple VMs in the job are copied one by one, subsequently. Data for VM disks are also copied subsequently, not in parallel.
