I have PCs, network media tanks on my network and I would like to backup or keep synchronized copies of certain folders on these devices on my DNS-323.  I would like to be able to set this up on the DNS-323 so that it automatically does the back up or synch are pre-scheduled times - i.e. I would prefer not to have to require a PC to be running performing this backup/synch.
Is this possible?  How would I enable it?  And if it is not, what options would you recommend to achieve this?
Thanks
