Daniel,

Coda supports one-level online backups.
That is done per Coda volume, not per file.
There has been a discussion about modifying the server to support
an arbitrary number of "snapshots", but nobody implemented that yet.
(that shouldn't be hard)

It has packaging problems, with its dependency on Cygwin.
I hope Phil will repackage it as an independent unit.
The client lacks also support for symlinks.

I would suggest holding your breath for a short moment
and then using the Coda's own transport protection instead of VPNs.
That is a lot more straightforward, as no host administration is involved.
In a sense, Coda is about avoiding host administration.

Not due to compression, but Coda is in fact bandwidth-efficient.
Compression (as well as multiple backups) is among those
relative easy low priority improvements which the community imho
would be able to contribute.
