Instructions

With standard Avamar replication, the source machine replicates internal system accounts to the target.
 
We see these internal accounts in the Avamar Administrator interface.

We see these internal accounts in the Avamar Administrator interface

We also see them under the /REPLICATE/sourceavamar/ domain. 
admin@targetavamar:~/>: mccli client show --recursive=true --replicated=true | grep _BACKUP
EBR_BACKUPS                          /REPLICATE/sourceavamar.domain.local 
AVI_BACKUPS                          /REPLICATE/sourceavamar.domain.local 
EM_BACKUPS                           /REPLICATE/sourceavamar.domain.local
MC_BACKUPS                           /REPLICATE/sourceavamar.domain.local

This behavior is intentional and occurs by default, unless replication options are selected to only include data for specific clients.

This provides redundancy on the target system for disaster recovery purposes.

The internal system accounts which are replicated contain information relating to various services provided by Avamar.

EBR_BACKUPS - Information relating to the VMware Backup Appliance where Avamar backs up VMware virtual machines
AVI_BACKUPS - Information relating to Avamar Installer, used for applying updates and patches to Avamar 
EM_BACKUPS - Information relating to Avamar Enterprise Manager
MC_BACKUPS - Information relating to the Avamar Management Console
