I really enjoy and recommend to everyone using a NAS configured with 
snapshots. It can be MDRAID and LVM. It could be ZFS. I use BTRFS 
myself. Or if you use a prebuilt NAS with its own operating system you 
go with whatever they offer.

With timeline snapshots (I use the snapper tool) you can easily go back 
in time. If something corrupts your files you can go get the older copies.

You also need backups, of course. But the snapshots are so easy to use, 
and faster to access.

I keep my snapshots hidden from Samba. But you can make them available 
in the filesystem or you can make them show up as a Windows Server File 
History snapshot. In either case definitely make them read-only.
