That depends on how you _want_ to partition.

Basically, you have the many choices of combining the following
two sets: GPT or MBR (GPT is recommended), "all in one" or highly
customized individual partitions.

It's hard to tell how much _space_ you're going to need, because
it depends on what you will install besides the FreeBSD OS. Further-
more, FreeBSD installs can be customized a bit at install time,
and if you recompile from source, you can have even more choice
on what to install.

As mentioned above, this is hard, maybe impossible to tell. You
should allocate - and that's not much more than a guell - a few
100 GB at least. That doesn't say anything about being able to
perform an OS install in _less_ than 10 GB, though. ;-)

FreeBSD supports both EFI and being booted via GRUB.

How are those backups organized? If you have a "pattern"
already, you can try to use that. If you're going to dedicate
that 1 TB disk to FreeBSD (should be absolutely fine for OS,
and probably have enough space for a lot of programs and data),
just make sure GRUB gets an appropriate entry for that disk.
Install FreeBSD as if it would be the only OS on that disk,
which in fact it is. You can temporarily remove any other
disks from the system to make sure no bad things (TM( can
happen. Use labels. Then recombine, add GRUB entry, and boot
into FreeBSD.

However, FreeBSD and Linux do organize and name things quite
differently, so don't assume that everything will be "the same"
on both ends. :-)

What you're attempting also depends on you backup/restore
mechanism which you didn't specify anything about. Is it a
whole disk dd image? Classic dump + restore? Some specific
other program?
