That should certainly work. Definitely back up the entire disk, though, as it
is too easy to make a typo and erase the wrong partition.
If your system has a GUI (or can forward over ssh to one that does), you might
consider trying gparted for this. It handles both the partitioning and
filesystem tools, and lets you queue up operations so you can see what the
overall effect would be. I do prefer command-line tools for most things, but
gparted is so handy that I would make an exception for it. (Not to be confused
with parted, which isn't just a text-based version of the same; it's a totally
different tool that only does partitioning and has much less functionality in
general.)
If it's just for builds, there's probably a minimal amount of data on
build-part that needs to be kept, so rsync'ing elsewhere won't take an
excessive amount of time or storage space. But you might be interested to know
that, depending on the circumstances, there may be ways to grow the filesystem
in-place, without having to recreate it and restore all the data (if all goes
well). In some cases you may not even have to unmount it.
If you want to know more, just ask. But please specify what filesystem type is
on build-part (ext4, btrfs, zfs, ...?).
