Dell PowerProtect Data Domain serves as a backup repository for my customers, where I began implementation with Avamar, using Data Domain as the repository, and integrated it with the ECS platform for cloud archiving. However, I have not performed file solutions to back up or attach directly to clients' PCs, as all backups end up on Dell PowerProtect Data Domain.
Most use cases for Dell PowerProtect Data Domain as a backup repository are in VMware backup environments, where I integrate it with IDPA, Avamar, and Veeam by installing proxies inside the VMware environment and performing all backup restoration tests and processes as needed. Although I have only performed replication once, in some cases I have installed agents inside Windows servers or customer PCs to perform agent backup or file backups.
Regarding my main use case with Dell PowerProtect Data Domain, I have not encountered any issues, though I would perform a replication scenario if the opportunity arose. Unfortunately, our customers in LatAm are not large enough for such projects, as their architectures typically involve active-passive or active-active setups for servers and storage, but not for backup solutions, which presents a challenge in educating customers on the need for proper disaster recovery or business continuity architectures.
