Do the Time Machine sparsebundles work better over AFP than they do over SMB? Since Apple lists this as supported I would hope the answer would be yes, but I'm a bit worried since I don't see why the SMB version wouldn't work and the AFP one would. (Same file access semantics for the bands in the sparsebundle as far as I can tell.)

E.g.: http://discussions.apple.com/thread.jspa?messageID=5918065#5918065

Apparently when the backup fills up on an SMB share, Time Machine can not delete the old backups so it ends up deleting all the old backups. If this works better over AFP then that would be great.

I am the poster of this apple discussion message. I am still puzzled by the fact that nobody else has run in the same pb than me (i.e. filling up the SMB partition, which leads TM to delete all but one backups).

In any case, Leopard is able to recover "free bands" from a sparsebundle over SMB using hdiutil compact... but not while deleting backups.

One could imagine that the situation is different with AFP, maybe bands are freed right away?
