Borg Backup works great for that, exactly it’s use case. It’s a command line thing, but you can use Vorta as a UI if you want that. If you have a NAS, it can back up directly to that.

I have a second cronjob in my setup that syncs the encrypted archive to B2 nightly. Works great

• htop
• docker
• zsh
• tmux
• ssh
• git
• rsync
• curl
• dnsutils
• jq
• nodejs (managed via fnm)

There are tools to detail the code coverage if your tests. I’ve worked with Istanbul in the past, and it’s helped to point out parts of the code that could use more attention

Hourly backups with Borg, nightly syncs to B2. I’ve been playing around with zfs snapshots also, but I don’t rely on them yet
