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!

Ah shoot! In my experience, their stock comes and goes. You should send us an email to know more!

My pleasure! Feel free to reach out if you have any questions!
