Issue DURACLOUD-957: Backup thread runs too frequently on synctool.
Currently the synctool's backup thread is running on the same schedule as the directory polling period which is 10 seconds by default. The back up thread period should not be tied to the polling period. Instead it should run at least every 5 minutes by default. Also thread synchronization on on the ChangedList.persist method is causing threads to wait until the backup file is completely written rather than waiting only until the file list is copied in memory.
