Hi Community,
We are designing a Commvault software (on-prem) solution, version 11.44, for a customer with 5 locations:
| Site | File Server Data |
|---|---|
| HO (CommServe + MediaAgent) | 2 TiB |
| Remote Site 1 | 10 TiB |
| Remote Site 2 | 6 TiB |
| Remote Site 3 | 1 TiB |
| Remote Site 4 | 1 TiB |
| Total | 20 TiB |
Setup:
- Single CommServe at HO, with a local MediaAgent and Disk Library at each site.
- File System Agent backup only (Windows file servers).
- All remote sites are connected to HO over site-to-site VPN.
- License: 20 TB capacity-based Backup & Recovery license applied on the HO CommServe.
Questions:
- Will one capacity license on the HO CommServe cover the file servers and MediaAgents at all 4 remote sites, since they're all registered to the same CommCell?
- Is usage calculated as the total FET of all clients across sites, with no separate per-site license needed?
- Since the source data is 20 TiB and Commvault counts 1 TB as 1024⁴ bytes, will a 20 TB license be fully used from day one? What happens if usage goes slightly over?
