How to use BitTorrent on D-Link Network Storage DNS-323?
That confirms I could buy two of these and use the first as a server and the second as the destination for incremental backups.
What happens after 20 days if I set the incremental backup limit to say 20, and schedule to daily? Does it start making a new set with a complete backup and incremental daily backups. Does it delete the previous set or retain it?
I didnt see any mention of compression of the backups so I'm guessing that is not available.
