I have a home server that I’m using and hosting files on it. I’m worried about it breaking and loosing access to the files. So what method do you use to backup everything?
Almost all the services I host run in docker container (or userland systemd services). What I back up are sqlite databases containing the config or plain data. Every day, my NAS rsyncs the db from my server onto its local storage, and I have Hyper Backup backup the backups into an encrypted S3 bucket. HB keeps the last n versions, and manages their lifecycle. It's all pretty handy!
