Maybe I’m just a simpleton but I run an rsync script each night. The beauty is that if I accidentally delete something I can easily recover it and if a drive fails I lose less than one days worth of data. This trade-off is well worth it for me.
If I had several drives I’d use SnapRAID to cut down on costs.
Oh and I’m lazy so I installed CentOS on it. In several years when CentOS reaches EOL I’ll just buy new hardware and install the newest version.
Synology type devices make me nervous. Krebs[1] recently did a piece on IoT gear being the new target for ransomware. I also wouldn’t feel comfortable exposing anything running on these devices to WAN.
