The organization's backup plans will be revoked from virtual machines, but will be preserved by 
Agent for vCloud. If you re-enable backup, it will be enough to reapply the backup plans to the 
machines so that the machines become protected again. 
The existing backups will be kept. If the backups are no longer needed, you can manually delete 
them from backup storages. 
1.6 Configuring the backup service
To access these settings, click the Settings tab.
System backup plans
This setting is used for managing system backup plans (p. 33).
E-mail server settings
These settings are necessary for sending e-mail notifications to organization users. Unless the e-mail 
server parameters are filled in, no notifications will be sent. 
The subject can include ordinary text and variables. In the received e-mail messages, each variable 
will be replaced by its value at the time of backup plan execution. 
The default notification subject is: 
[Backup service]: %Organization name% - %Backup plan name% 
Where:
%Organization name% is the name of the organization.
%Backup plan name% is the name of the backup plan.
Other variables are not supported.
Tip E-mail notifications to a system administrator are configured on the management server. Go to Options > 
Management server options, and then specify the e-mail server settings in E-mail settings. In Alert 
notifications, you can select the specific alerts to send notifications about. 
Backup and recovery options
Simultaneous backup 
Specify how many virtual machines Agent for VMware may back up simultaneously. The default 
value is 5. The maximum value is 10. 
The value you specify is effective for a backup plan. If an agent runs more than one backup plan 
simultaneously, the number of machines being backed up may exceed the setting, but it still 
cannot exceed 10. A backup plan that requires to back up the 11th machine will not start until 
one of the backup operations is finished. 
Tip. Simultaneous backup of multiple virtual machines increases the amount of CPU resources 
used by Agents for VMware. By default, Agent for VMware uses two virtual processors. If you 
observe that CPU usage during backup approaches 100%, increase the number of virtual 
processors in the virtual appliance settings. This may significantly increase the simultaneous 
backup performance. 
Network connection speed 
Define the amount of network connection bandwidth allocated for transferring the backup data.
