Uh-oh. Poor-man's SAN? ;-) This isn't going to scream, performance wise.

You should use ext3 since you'd want to avoid fsck'ing that 273 gig over
the network as far as possible. Unmount, run tune2fs -j on the image, 
then remount as ext3.

Ah, you need to stop backuppc, then mount, then start it again.

Looks good to me.

ext3 (which is ext2 plus a journal) preserves the user id and file
permissions of files stored on it (the uid/gid option is a workaround
for Samba->Linux integration), there is no point in setting one at mount
time. You have to copy the pc directory with "cp -a" or "rsync -aH", if I
remember correctly, so all file permissions etc. are preserved.

You are very close. :-)

HTH,
