  • I agree with this, though it’s not the easiest option. Ceph is amazing for storage, I am using mini pc nucs for my cluster and to expand storage I simply plan to add nodes and get the largest sata and m.2 SSD.

    I recently setup velero for automated backups. It even is configured to dump my HA postgrrd DB and then backup the dump folder.

    Other cool experiences I can think of is netdata with Prometheus metrics auto scraping pods by their annotations to pull their statistics in, and nothing is more satisfying then making a service highly available.



  • Setup backup hooks with velero and kopia on a HA postres cluster this week. Biggest DB is Lemmy and that shrinks by a factor of 10 using pgdunp with custom archive. Dumping is 100% the way to go!

    Similarly I should do this for my sqlite applications, it looks like kopia can’t do incremental backups with them and thinking about it, it makes sebse, likely sane reasons you mentioned.




  • Flakes is a way to manage nix, nix is essentially a package manager, NixOS would be probably easiest way to play with these tools.

    You define a flake / nix configuration and they are designed to be installable on any system. Think of it as if you install and configure all of your programs, services, environment in it and you upgrade to a new PC, you run a command to install your flake from your previous PC and everything is configured how you had it on your previous PC.

    Flakes is a new tool and is under rapid development, so it may have breaking changes in the future, but it is so popular that the devs are trying not to break it as much as possible.

    Also take my comment as a grain of salt since while I know about flakes and use it, I am nowhere close to an expert on it and terms that I used may be incorrect especially for defining them, but in layman’s terms I think its a decent introduction to what it is.
