The syncs preferences panel allows you to set how many days worth of journal history to keep on the realtime synchronizations.  This is the longest period a [CrushSync] client could be offline and still be able to "catchup" to the current state.  If they were offline longer than this period, it could result in them re-uploading files that other users had deleted.

(there may be more configurations items coming soon to this area)
