I'd agree with this. On my home system I back up to both NAS and to
USB. As Robert rightly says, I used the NAS as a shared
(cross-platform) drive, so it was available for backup too, and that's
why I used it, not because it was easy! On the contrary, samba was not
reliable, and cifs was difficult to get working (permissions are an
inherent problem, it seems).
So if you just want to use the drives for backup, I'd go for USB as
being the simplest option. (And a couple of USBs has the other
advantage Robert mentions in his post - the possibility, if you wish, of
off-site storage. I carry some important backup data with me, on a
little 100Gb Seagate portable USB drive)
As a home user, I tried several GUI-based back-up apps. I did not find
one that did what it promised in all departments. I eventually went
back to rsync, which, once you've got it set up - perhaps with a script
- just works. (BTW, rsync still gives me errors when trying to sync
ownership and permissions to the shared FAT32 NAS, which is another
reason for keeping things simple with USB if you can.)
NAS is great for what it's for - sharing storage space and data on a
network. But it's less less than wonderful for Ubuntu backups. As I
say, if you just want backup storage, I'd recommend sticking to USB drives.
FWIW, that's my two-pen'orth. HTH
