Backup Design Recommendations

Hello Veeam Gods,

Newbie here, looking for some advice on system design… I’m hoping I’m in the right place, but let me know if I’m not.

Here’s the stack:

DC1:

3x ESXi Physical Hosts

1x VCenter Physical Server

1x Win22 100TB Storage

Non-Prod Nimble System with 40TB storage

All on 25GB backbone

LINK: 100gb fiber connection DC1 --> DC2. Separate buildings, power, generators, WAN etc.

DC2:

3x ESXi Physical Hosts (same spec as DC1)

1x Veeam Physical Server with VBR + Explorers removed

1x 600TB Ubuntu hardened Immutable Storage

All on 25GB backbone

WAN:

2 x 2GB redundant WAN connections (1 into each site but HA across the two, redundant firewalls too)

Wasabi Buckets for Offsite S3 storage.

The Plan (that I’d like guidance on):

Run Production in DC1

Use CDP to DC2 for near-real-time failover

Backup Production in DC1 to the 100TB Storage in DC1 (store short term backups - sub hourly)

Copy Job to DC2 600TB Ubuntu Immutable (store short and longer term backups - sub hourly, hourly, daily, weekly, monthly)

Copy Job to Wasabi Cloud (store daily/weekly/monthly backups)

Use Nimble System for SureBackup / Virtual Labs.

What am I missing / What would you recommend? I’m sure I’ve not covered everything here, but it’s the high-level architecture. VMware Hosts and Network are massively oversized, so there’s really no constraints there. We’ve been running on 1GB network until 2023, so 25/100 is not a concern.

Appreciate any guidance and suggestions that the community can offer!

Thanks all!
