Unlike Syncplicity (dropping Mac support, failing most of Backup Bouncer), Dropbox passes Backup Bouncer!

That’s a clean slate for rsync 3.0.6 (patched) and for Dropbox (provisionally)! Nice to know Dropbox should keep my OpenMeta tags intact. At work tomorrow, we’ll see if Dropbox still passes, on the other end of the Dropbox wormhole; that will be the real test of Dropbox.

UPDATE: Not surprisingly, Dropbox doesn’t look as pretty on the other side of the wormhole. It mostly fails everything, so only use it for self-contained files (no extended attributes, no specialized metadata, no resource forks; just timestamps and bsd-flags).

So … be careful. On the origin end, your file is fine; on the other end of the wormhole, it might be mangled.
