The Synology has netatalk configured out of the box so it can be seen in the network as an AFP share and can be used as a destination for TimeMachine backups (I'm not using it in that way but a couple of friends who use Macs told me it works well).
It also has a package to backup data stored on the Synology to Amazon Glacier, and that is something I'm going to enable soon in order to improve redundancy (and to have an off-site copy of my data).
On top of that some of that stuff is also spread between Dropbox, Drive, Github and thumb drives. I might have like three to five copies of each file at any given time.
