From my long experience in IT I would recommend you to avoid HA/FT setups if possible. It is not easy to implement HA/FT right and often it is not really required.
The starting point of every DR strategy must be proper backup/restore 101: backup what and why (not how). This is the only way to cover all kinds of outage (and no snapshots are not a proper backup).
HA/FT comes on top of this and help to avoid/shorten an outage at the cost of added hardware cost and operation complexity. As long you don’t really need to I would recommend focusing on backup/restore and only consider HA/FT in case your recovery time objective (RTO) is shorter than restore duration, accept added cost and undestand and can manage additional complity.
