Backup

1. What if something breaks tonight?

   Sunday, just after five, and an update has broken a service. How my homelab gets through a night like that, and who tells me when it can't manage on its own.

2. Nextcloud on S3 instead of a disk

   My Nextcloud doesn't keep a single file on its own disk; each one becomes a numbered object in a bucket at Hetzner. Here is what that buys me, what it costs, and why the bucket on its own is still not a backup.

3. compose-backup: back up, encrypt and version Docker stacks

   How a small tool of my own packs every Docker stack ready to move, ships it encrypted to S3, and turns a plain mirror into 30 days of history.
