Hello there! Here’s the thing: I got some old HDD for my Debian home server, and now that I have plenty of disk space I want to keep a backup of the OS, so that if something accidentally breaks (either SW or HW) I can quickly fix it.

now the question is: which directory should I include and which should I exclude from the backup? I use docker a lot, is there any docker-specific directory that I should back up?

    you could “dd” your root partition to a partition on that HDD every now and then. and if you don’t have your home on a different partition do that and it’s easy to back this up with a syncing tool if u decided to do that or at least the .config .local and .cache directories because many programs put their configuration files in there.

    BE VERY CAREFUL WHEN USING “dd” BECAUSE IT CAN MAKE YOU LOSE DATA FOR A WHOLE PARTITION OR DEVICE

    docker keeps some data in ~/.local/share/docker btw
