well if you dont need conflict resolving, i'd rather take the manual row by row flag checking (maybe a date_modified timestamp column) and synchronization...
and you also possibly could do a little bit of conflict resolving, as long as you dont need to merge source and dest and can pick either one
thats for the db sync portion
for filesystem data, metadata can be checked and matched to determine if the file has been changed and need sync or not...
@fluf without knowing details about what are you trying to achieve, its impossible to tell you a useful alternative, i hope you understand that :D
