What exactly do you intend to backup (and why) onto a second
partition on the same disk? Sure, it is possible to do so,
but you should make yourself clear _what_ you want to do and
why, then it will imply _how_ will do it the best way -- even
though there might be more than one best way... :-)

Also depending on your needs, 5GB may be too few to hold a full
installation of OS and programs (even though I've managed to
get a full 5.2 installation plus tons of programs on a 6 GB disk,
with 50% of free space afterwards).

What do you do with the remaining 900 GB of the disk? :-)

Also, please make yourself familiar with the terminology of what
a partitions and what a slice is, and see it in the proper context
of MBR vs. GPT partitioning.

If I take your use of the TT (termini technici) literally, you
would have one partition containing everything rooted to /, and
a second partition that contains the same. You would either manually
have a backup mechanism from the 1st to the 2nd partition, or you
could configure them in some automated mirroring mechanism. But
I don't see a real use case when doing so on the _same_ disk.
Still it would be possible, and it could even be helpful in some
bad case scenario.
