In which case it's not a case of iSCSI vs <something>, it's NAS+iSCSI 
vs <something>.

Personally, I would choose NFS over SMB for storing Linux files - for 
the simple reason that the file system semantics are directly 
compatible with the files being stored. I've no idea how it compares 
with SMB though - and in any case again it's not a case of NFS vs 
SMB, it's <implementation of NFS> vs <implementation of NFS>. It's 
entirely possible that vendor A's box does SMB better while vendor 
B's box does NFS better.
I'd still choose Rsync if available for a Linux client.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon 
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the disk and re-install the 
printer OS on it. If anyone knows where I might get hold of one I'd 
be grateful - requests to Canon drew a blank, it's been out of 
support for years.
Alternatively, if anyone has one of these and would let me image 
their hard disk ...
