I do not think so. Everything is valid. I am afraid you either lack the
capacity or the experience to understand.

I happened to work with Veritas Appliances in one of the projects couple of
years ago. Veritas bought it from Symantec. The appliances cost hundreds of
tausands. Have nice GUI and various modules for databases, VMWare
integration etc. It also uses snapshots to backup systems. And I personally
did test complete restore of a whole production environment: 10 blade
servers with 40+ VMs, 3 bare metal servers, varios databases, etc. etc. ...
I think I know something about backup systems and requirements for use in
critical infrastructure.
When looking for a system to use at home that does deduplication and can be
easily used to restore 2-3 machines I discovered borg. Reviewed, installed
tested. Works great. Why not recommend to someone who is asking for backup
solution?
However the discussion that emerged is for me a bit surprising. 
I do not want to insult anybody, but ... anyway,  I stop here.

You know, at the end may be it is better for you to stick to rsync.
Simple minds - simple tools.
