I'm using hierarchical backup. Logfiles of backups could tell when and how maleware spread. And even more important, one can restore a system after infect quickly.

I'm using a detached screen for ssh master control, and an rsync script to sync servers to my backup server, from where hierarchical backup is done to USB disks in the most simple way: `cp -al` and rsync. I have 3 piles of disks. One attached, one in the shelf, and one at a neighbor and shuffle them weekly.

I'm using network scans, and keep things containerized with tight fitting firewall rules.
