Backup solution for customer with a primary and secondary data center on the same campus.. Backed up fileserver data should be replicated across the data centers by VLT replication after a backup…
The correct answer is A. 2620 backup system. Given the relatively small daily backup volume of 900 GB with a low change rate and 120-day retention, an entry-level Dell EMC Data Domain system, represented by the 2620, is the most appropriate and cost-effective choice for this customer.
Question
Backup solution for customer with a primary and secondary data center on the same campus.. Backed up fileserver data should be replicated across the data centers by VLT replication after a backup completed. The customer give you sizing requirements:
- Backup of one file server with 6 partitions,150 Gb each Daily full
backup
- Daily change rate by less than 1% of original data
- Backup application is DP 7.01
- Retention time is 120 days
- Uni-directional replication between sites.

Why each option
Given the relatively small daily backup volume of 900 GB with a low change rate and 120-day retention, an entry-level Dell EMC Data Domain system, represented by the 2620, is the most appropriate and cost-effective choice for this customer.
An entry-level backup system like a Dell EMC Data Domain 2xxx series (which '2620' represents) is well-suited for the specified workload of 900 GB daily full backups, a less than 1% change rate, and 120-day retention, as the effective deduplicated logical capacity needed is manageable for such a system.
The 4210 is a mid-range Data Domain system designed for larger environments and significantly higher capacities than the customer's modest requirements, making it an oversized and uneconomical choice.
The 4220 is a mid-range to high-end Data Domain system, providing capacity and performance far beyond what is needed for a single file server with less than 1 TB of daily data and a low change rate.
The 4420 is a high-end Data Domain system intended for large-scale enterprise backup solutions, which would be excessive and unnecessarily expensive for the described customer requirements.
