Is using multiple partitions a good data protection strategy?

Is using multiple partitions a good data protection strategy?

So this is what I'm thinking of doing: Have 3 partitions on my laptop's
HDD - 1 for system files (C drive). One for the data (D). And one for
backups (Win 8 file history etc).
And then I backup all these drives using Acronis True Image. Is this a
good strategy to protect my data?
Right now, I have only 1 partition with all my stuff on it (1 TB HDD with
about 150GB filled up).
