Why make Difference between HyperV and ESX VM Replication?

[wal_ter]

I've read in the B&R User Guides that HyperV VMs get replicated in reversed incremental Mode and VMware VMs forward incremental.
Is this because they differ in how they perform snapshots?

Thanks

In VMware VM snapshots are used as restore points (snapshot tree can only be forward incremental). As to Hyper-V, then we are using Veeam's proprietary replication engine (previously used for VMware too) which has always been reversed incremental (each restore point is represented by a VRB file).
