Execute sync command before creating vol snap
The sync command on linux and windows flush on disk the memory held at kernel level. Would be good if Freezer execute sync, just before the vol snap creation or just before the backup execution in case the backup is not configured to use vol snap.
the sync execution should be managed with try: exception as if the execution fails, it should be logged, but it shouldn't stop the freezerc execution.

Whiteboard
Since freezerc don't know what fs is used underneath, only if the fs is jurnaled we can be quite confident that the status of the data we are backing up is consistent.
IMHO, the sync should be done in all cases, lvm or not, cinder, nova or whatever type of backup we are taking.
