Veeam Backup Manager

Started by Veeam Backup Service and is able to access

the database
Runs a job from start to finish and understands the actions it’s supposed to take, such as:
Connecting to vCenter over HTTPS or Hyper-V host over WMI
Snapshot creation/removal
Retention calculation and any other kind of job logic
Direct communication with data movers (aka VeeamAgents).

Veeam Backup Manager

A job is almost any kind of activity that

Veeam Backup & Replication can perform:
Backup, replication, backup copy, etc.
Any restore is a single-run job
Any system jobs such as configuration backup, rescan, SAN rescan, tape infrastructure rescan

Processes that do the “heavy lifting,” data transfer work

associated with a proxy or repository
For example, during a VMware backup job:
Source agents read .vmx, .vmxf, .nvram and .vmdk files
Target agents write backup files to the repository folder/share
