Comobo Backup and Truecrypt FDE

Dear Comodo team,

I’m using Truecrypt for a full system encryption of my main harddrive, transparently encrypting C:, D: and F:.
Comodo Backup sees those partitions as normal Windows partitions.
when I select C: and D: for backup sources and tick “Track0 and MBR”, what will that exactly mean?
Will it backup my full system encryption MBR? And what would restore do then?

And what would be the case if i hadn’t encrypted my entire harddrive but my system partition in particular?

Thank you in advance
