I have a Synolgy 2 x 2TB RAID as a server which acts as a local backup.

For a remote backup, I use Backblaze - US$60 per year and fully automated unlimited backup. Backblaze

I have tested file recovery from Backblaze and it works easily. I opened the account when I still owned a business and was so impressed with the value for money that I have kept it going into retirement.
