Have you wanted to take a look at OPNsense without installing it to a dedicated machine and/or deploying it as your primary home router/firewall? The easiest way to evaluate OPNsense without installing it on separate hardware is to virtualize it. I wrote about running OPNsense in VirtualBox. Now that I run Proxmox on my server instead of Ubuntu (I still use Ubuntu for many of my LXCs/VMs on Proxmox), I wanted to run OPNsense on Proxmox so I may use when writing content for this site.
After I migrated my home server to use Proxmox, I began searching for a new offsite, cloud backup solution. I was using CrashPlan, and my discounted subscription expired. I wanted to know if I could keep the offsite backup costs a little lower than $10 per month (even though that is not a huge expense to ensure your most important files are protected) and also run a lighter weight service.
For a number of years, I have used Crashplan as my offsite backup. I found the price and features attractive. It also worked on Linux which further won me over since I was running a Linux server as my file server. Their unlimited plan for a single machine was very affordable especially when purchasing multiple years. $3-4 per month for unlimited backup was well worth the price to have peace of mind in case something bad happens at home (I actually did need to use it one time when I had a failing hard drive corrupt several of my files).
