This is a short recap of what's needed to set up a regular backup of a Synology shared folder onto an USB drive plugged on an Asus router (running with Asuswrt Merlin).
The information needed for this specific operation is generally scattered in different places, so I regrouped everything while it's still fresh from my recent actions.
Asus routers are excellent but choosing a model can be tricky due to all the variants available.
If you don't want to invest in the ultimate beast, you can still get some great value for money in budget-friendly models like the RT-AC1200 and RT-AC1200GU once you know where and what to look for...
There are many WiFi-N routers on the market, but add the Gigabit requirement, and this choice drops dramatically. Add a further requirement for an embedded ADSL modem, and you're left with just a handful of candidates left.
Following a recent horror story with my 3G Broadband operator, I started to look for a router with a security
feature that would warn me when I reach the data usage limit and, if possible, disconnect the modem.
