Tomato, tomaahto... :)
The point was basically "any block-level attachment (except maybe USB)".
The problem comes from NFS' poor handling of the zillions of hard links
that BackupPC wants to use.
iSCSO/eSATA/Firewire are all block-level protocols. NFS/SMB are
file-level protocols. It's the file-level protocols that either wont'
work at all (SMB) or work very poorly (NFS). If the system is given a
block device it can format with something sane (EXT2/4/XFS/JFS) then
you'll be just fine, modulo the performance of the connection between the
computer and the device.
