An expensive way too go.
If wanting Raid for performance, then Riad0 is the best option.
But this is not really a Raid set up.
Hence no fault tolerance.
Yes True Image will clone/backup Raid0 to another drive. This drive doesn’t even have to be Raided.
Of course when wanting to restore, Raid setup is necessary.
Other Raid setups, if you have True Image are not necessary.
No real performance gain.
The mirroring can be overcome with True Image by updating your backups.
You can set this up @ time of creating your 1st backup.
The problem with Raid is that in terms of what you’re referring to (s/w Raiding).
It is the s/w that fails most.
So even with Raid1 for example data is lost.
