On: The new Dropbox

[hedora]

You can work around failures of large initial unison syncs by creating a partial directory tree on the target manually.

It treats the creation of a new directory as an atomic operation, and rolls it back on failure.

(So, if the initial sync will take a week, then precreate the top level or two of the directory hierarchy...)

It’s an annoying problem, but after the initial sync, partial syncs are fast and reliable.
