Thanks, that is a helpful explanation. Most on premise solutions we use also have snapshot based backups and not bare metal installs. Sounds like the recommendation is to not use BTRFS if that type of backup is available which is somewhat interesting. Understand the issue with access to the boot loader. An interesting thing to think about related to depending on the cloud architecture for the backups/rollbacks/snapshots is there are still limitations with the technologies available. For example, Azure Backup cannot support anything with a disk >1TB currently, which many SAP systems will obviously have.
