With 184.108.40.206 issuing a simple --backup on an nfsdatastore (no other options given) for a windows 2016 server machine I got erro 1223 could not create snapshot:
2021-08-28T13:42:23 | Error code 1223 at file esxi.c, line 1223 | Error description: could not create snapshot in win16-50, error: Create Snapshot:
As I was issuing manually the command I was worried and checked in snapshot manager but the XSI snapshot is there. Also checked vmware.log but no error there:

I am a bit suprised that XSI did not stop and continued with vmdk backup. Is that behaviour expected?

Check the Windows task manager log. You might have some DB server that requires quiescing inside that VM.
Yes, snapshots are absolutely crucial to creating a backup, without a snapshot there can't be a backup.
