Making Time Machine work with the ReadyNAS

Along the same lines ... Apple doesn't officially support writing Time Machine backups to any network device other than a Time Capsule. The explanation that's made the rounds as to why a USB disk attached to an Airport Extreme - nominally the equivalent of a Time Capsule - isn't supported is that only the Time Capsule supports some kind of ack - presumably a "the data you wrote is actually on the disk" - that is needed to ensure the backup is actually usable in the event of a failure. As best I can tell, this is done using an undocumented extension to AFP implemented only by Time Capsule (and maybe by Mac OS Server? I don't recall if Time Machine backups to disks exported by Server are supported).

Has anyone at Netgear looked into what's actually going on here to ensure that Time Machine backups are not damaged in the event of a failure - e.g., a crash or just plain network disconnect while Time Machine is running?

I've been using my NV+ to do Time Machine backups for a while now. I figure that even if this feature isn't there, it's still a hell of a lot better than not doing backups! But it would be nice to get any extra assurance....
