To be able to increase backup retention, the company has bought a Data Domain deduplication appliance.
After setting up the jobs to use it, the backup administrator observes an increase of resource consumption on the backup server. The proxy configuration has not been modified.
What is causing the issue?
When integrating a Data Domain deduplication appliance with Veeam Backup & Replication, it is typically used as a backup repository. The backup server may need to take on the gateway role, especially if the Data Domain is integrated over NFS or CIFS. This means that the backup server will be responsible for processing the data flow between the Veeam proxies and the deduplication appliance. If the gateway server (backup server) is not well-resourced, this additional workload can cause an increase in resource consumption on the backup server. The appliance's resources and the SSL certificate are not related to increased resource consumption on the backup server, and simply needing additional resources for deduplication (D) is not specific enough without indicating the gateway role.
