I recently upgraded from 10.6.8 to 10.9. on snow leopard i was able to make time machine backups over the network to my nas, i think i had to tweak some settings but i dont recall what i did. now that i upgraded to mavericks, i cannot do backups to my nas using time machine. my question is, what do i have to do to allow time machine backups over the network in 10.9? i tried looking for solutions online but did not find anything relating to mavericks.
