1.  Upgrading SMS existing server via CPUSE after verification is clear is there any other checks that need to be made ? How long does install take ?  
Always check the /var/log/messages
How long?: depends on the quantity of cores, the size etc. at least 60 minutes to appr 4 hours.
2. I will snapshot server but any backups I still may need to take and which ones ?  
Always do neccesary + 1 backups. I do the followings (yes all the 4):
- CP snapshot
- System backup
- save configuration
- migrate_export
3. Will R81 Gateways and endpoints continue to work and SIC remain established once SMS is running R81.20 ?   
- Of course, SIC won't change
4.  Upgrade of the Firewall Gateways themselves via CPUSE what back ups do I need as these are appliances.  How long does upgrade take ?  Is there a quick recovery process ?
- CP snapshot
- System backup
- save configuration
The quickest recovery is revert from snapshot 
How long? 30 mintues to 90 minutes
5.  Upgrade of SMART-1 252 Log Server which is a physical appliance.  Whats the best way to backup this system and restore from it should upgrade fail?
- CP snapshot
- System backup
- save configuration
The quickest recovery is revert from snapshot 
6.  Whats the recommended disk space rquired for upgrade for SMS , Gateway and Log server ?
At least the root partition. Run "verify" and  it will checj the requirements
