There's this post about using snapshots for NFS-based vCenter:
Unrelated to SnapCenter: I used to use built-in vCenter backup schedule to dump data to external location.
I restored it twice (6.7U3 and 7.0U1, back then) after some plugins messed vCenter up, by deploying vCenter with a script (10-15 min), and then restoring data from my HTTPS backup. It worked fine both times. But my environment didn't have any of the challenges from the list of limitations:
The links are for vSphere 8, but the info for 6 and 7 is similar.
Different destinations: don't know if SnapCenter can do it, but you can snapshot-and-FlexClone the destination - not sure if that would work for you.
Another possibility - if SC or cloning isn't feasible - would be backup to S3.

VMware-specific bit: https://docs.netapp.com/us-en/bluexp-backup-recovery/task-restore-vm-data.html
This also requires a working vCenter, it appears.
