Backup Policy Application Methods
To ensure that settings of Veeam Agent backup jobs on protected computers are up-to-date and do not differ from backup settings specified in the backup policy, Veeam Backup & Replication regularly applies the backup policy to protected computers.
TIP  | 
You can also apply the backup policy to protected computers manually, if needed. To learn more, see Applying Backup Policy to Protected Computers.  | 
There are two methods to start the policy application process:
- By Veeam Backup & Replication
 
Veeam Backup & Replication applies the backup policy to protected computers at the following events:
- At the time when the backup policy is created.
 - At the time when you start the backup process manually in the Veeam Backup & Replication console.
 - At the time when Veeam Backup & Replication performs scheduled rescan of protection groups added to the backup policy. Veeam Backup & Replication automatically rescans a protection group upon schedule specified in the protection group settings.
 
NOTE  | 
Keep in mind that Veeam Backup & Replication cannot apply backup policy to protection groups for pre-installed Veeam Agents and their members. For members of such protection groups, the policy application process can be started only by Veeam Agent.  | 
- By Veeam Agent
 
The Veeam Agent service running on a protected computer regularly synchronizes with Veeam Backup & Replication and checks whether job settings obtained from the backup policy are up-to-date and updates backup job settings, if necessary. Veeam Agent performs the synchronization every 6 hours.
You can also synchronize Veeam Agent with Veeam Backup & Replication immediately running the following command from the Veeam Agent computer:
- For Veeam Agent for Microsoft Windows computers:
 
"C:\Program Files\Veeam\Endpoint Backup\Veeam.Agent.Configurator.exe" -syncnow  | 
- For Veeam Agent for Linux, Veeam Agent for Oracle Solaris, Veeam Agent for IBM AIX and Veeam Agent for Mac computers:
 
veeamconfig mode syncnow  | 
During the synchronization session, Veeam Agent performs the following operations:
- Connects to Veeam Backup & Replication and obtains from the Veeam Backup & Replication database information about backup policies to which the Veeam Agent computer was added.
 - Compares obtained backup policy settings with backup job settings in the Veeam Agent database. If the settings differ, Veeam Agent performs the following tasks:
 
- If backup policy settings and Veeam Agent backup job settings do not match, Veeam Agent updates backup job settings in its database.
 - If the protected computer was added to a new backup policy, Veeam Agent creates a new backup job on the protected computer.
 - If the protected computer was removed from the backup policy, Veeam Agent removes the Veeam Agent backup job on the protected computer.
