I actually was speaking to someone that had the same queries as you yesterday, and as you say Storage Snapshots are so fast and great for recovery time and point objectives. But to emphasise what Andreas has said if its on the same ONTAP (WAFL) system being moved from A to B then all good data but also bad data will also be stored and replicated. I always suggest using Storage Snapshots and a backup to that different media type with also a copy offsite. here were my quick notes back to the query.
1st line of backup - Storage Snapshots orchestrated by Veeam, this may or may not include replication to secondary array, these can be application or for an even faster RPO crash consistent could be used depending on Application. (Scenario - VM, File etc failure, really fast RPO/RTO requirement)
2nd line of backup - Backup from Storage Snapshots to a secondary media type, some spinning disk next to the production rack this will hold short term retention for fast recovery. (Scenario - Production storage failure, restore requirement outside snapshot retention)
3rd line of backup - Backup Copy / Backup from Secondary Storage Snapshot, getting that primary backup data over to a secondary or offsite location this could be a similar retention to 2nd line or this offsite copy could be for longer term retention. (Scenario - Production site failure and long term retention restore if requirement outside primary backup retention)
