If your NAS doesn't provide NFS, many do provide iSCSI, which is just
like a disk but attached via network. Can be partitioned (if wanted),
formatted with the filesystem of your choice and mounted.

On a side-note: From 3+ years with backuppc on various installations
one tip: Don't use backuppc with external storage. Use it with a disk
directly in the machine where its doing its processing. Build your own
backuppc-machine, run it as a virtual machine with enough disk,
whatever. But don't make your fail-safety depend on external resources.
When you have backuppc on a machine with enough disk, its just a matter
of this machine running. When you have backuppc on one
(virtual-)machine depending on storage from a second machine (or NAS
for that matter), its a matter of two devices running and
communicating. So instead of a_1 for the availability of
backuppc-machine with range [0:1], its
  a_1 * a_2 (* a_3)
where
  a_1 = availability of backuppc-machine
  a_2 = availability of storage-device
  a_3 = availability of connecting switch/infrastructure
all with range [0:1].

Lets assume all are up to 99%, that is a_1 = a_2 = a_3 = 0.99, then the
single machine solution gives you an availability of 99%, while the
multi-device-solution gives you 0.97, that is 97% availability maximum.

And then there is the installations where the backuppc-machine is also
the router and dhcp-server. So the dhcp-server won't start because it
can't mount the backuppc-storage. And the NAS won't start because it
can't get an IP...

tl;dr:

Don't use NASes as external disk for backuppc. Only save archives
('tapes') to external iSCSI-, NFS- or CiFS-resources.

Have fun,
