Veeam Backup & Replication 9.5 Update 4
Veeam Agent Management Guide

Before You Begin

Before creating a protection group, consider the following prerequisites and limitations:

  1. When Veeam Backup & Replication performs discovery of protected computers, Veeam Backup & Replication connects to every computer added to the protection group. If you instruct Veeam Backup & Replication to perform discovery immediately after the protection group is created, make sure that all computers added to the protection group are powered on and may be accessed over the network. Otherwise, Veeam Backup & Replication will be unable to connect to a protected computer and perform the required operations on this computer.
  2. A protection group that includes Microsoft Active Directory objects can include objects from one domain only. To add to the inventory computers that reside in another domain, you need to create a separate protection group and include in this protection group the necessary objects from that domain.
  3. Veeam Backup & Replication automatically excludes from the protection scope Active Directory objects of the Group type that exist in a parent Active Directory object (organization unit, container or entire domain) specified in the protection group settings. To instruct Veeam Backup & Replication to process a group, you must select this group explicitly in the protection group settings.
  4. You cannot add and/or exclude universal and domain local groups to/from protection groups that include Microsoft Active Directory objects. Only global groups are supported.
  5. It is recommended that you do not add a computer to a protection group by specifying a dynamic IP address assigned to this computer. If such computer receives another IP address from a DHCP server, Veeam Backup & Replication will be unable to discover the computer and perform on this computer operations defined in the protection group settings.
  6. It is recommended that you include each computer in one protection group only. For example, if you have added an Active Directory container to a protection group, it is not recommended to add a computer that exists in this container to another protection group. Adding computers to multiple protection groups with different computer discovery and Veeam Agent deployment settings will result in additional load on the backup server.
  7. You can add a cluster only to a protection group that includes Microsoft Active Directory objects. You cannot add clusters to protection groups that include individual computers or computers specified in a CSV file.
  8. To deploy Veeam Installer Service and Veeam Agent for Microsoft Windows on a protected computer, Veeam Backup & Replication uses the administrative share (admin$) of the target computer. An account that you plan to use to connect to a computer included in the protection group must have access to the administrative share.

Note that in client Microsoft Windows OSes access to the administrative share is forbidden by default for local accounts. You can enable this option with a registry key. For details, see this Microsoft KB article.

  1. Veeam Backup & Replication does not support usage of a Linux account with the modified PS1 shell variable to connect to a computer included in the protection group.
