Last year I wrote a blog post about how to use LXC containers on a VPS. I've been running this setup for quite a while now and it has been great. However, my approach involved making full copies of my containers. Not very space or cost efficient!
So it was time to revisit my backup strategy: I started using Duplicity to take incremental and encrypted backups of my LXC containers. I also switched from Amazon S3 to BackBlaze B2 to further reduce my storage costs.
