vmProtect usage questions

Scenario: We have 2 ESXi hosts (unfortunately operating under 2 separate Essentials licenses) on the same LAN. They have no shared storage for auto VM failover (license also prevents this), but we do have a QNAP NAS available which can present a 'shared datastore' to both ESXi hosts. AS with most NASes the QNAP can present storage in any of the following ways.... NFS, iSCSI, SMB, FTP, etc. The questions below relate to the best way to a) setup vmProtect backups and b) the best way to provide failover of VMs between the 2 ESXi hosts. Intent is ESXi hosts will run VMs from ESX host local disks (~1.5TBytes each ESXi) and the NAS will be used as primary backup destination (~15TBytes of storage available). Offsiting of backups will be (at this point) via rsync-ing of backups to remote QNAP NAS at WAN location.

Q1) vmProtect appliance - Backup destinations.
4 different locations are listed as available. OnlineBackup storage, Local, network, FTP/SFTP.
Can you confirm that these backup destinations are all relative to the appliance. eg. Backup data path is from ESX host to vmProtect virtual appliance to destination.?

Q2) IF ESX host 1 (which theoretically hosts vmProtect) catastrophically fails, can you briefly describe to restore ESX#1's VMS to the other ESX host (ESX#2)?
Would ESX#2 require a separate vmProptect virtual appliance?

Q3) Same scenario as per Q2, briefly describe how ESX host 2 could run ESX#1 VMs directly from backup?

Q4) Are the files created by vmProtect rsync friendly and therefore suitable for remote replication to a remote/WAN based NAS/location ?
eg. Does vmProtect create an initial full backup file and then create incremental files there after?

Q5) How would we need to setup vmprotect to manage 2 separate ESXi hosts operating under 2 separate VMWAre essentials licenses? Single vmProtect license or 2 vmProtect licenses?

Q6) Will vmprotect replication run across a WAN to a remote located ESXi host?

Q7) Any recommendations on how to use vmProtect in this scenario to provide backup to NAS and allow recovery of vMs to alternate ESXi host and to ?
