Volumes

Docker Volume Management: Backups, Migration, and Best Practices You’ve got a dozen containers running — Nextcloud, Jellyfin, Paperless-ngx, databases. Each one stores data in Docker volumes. But can you actually back them up? Migrate them to a new server? Clean up the dead weight? If you already understand the difference between volumes and bind mounts, this guide picks up where that leaves off. We’re covering the operational side: how to protect, move, and maintain your Docker volumes in production. ...

Complete Guide to Docker Volumes and Bind Mounts Every self-hosted container you run — Jellyfin, Paperless-ngx, Nextcloud, your databases — needs to store data somewhere. Kill the container without persistent storage and everything’s gone. Docker gives you two main options: volumes and bind mounts. Understanding when to use each is one of the most important skills for any self-hoster. The Problem: Containers Are Ephemeral By default, any data written inside a container lives in its writable layer. When the container is removed, that data vanishes. This is by design — containers are meant to be disposable. ...

compose-backup: One-Command Backup for Docker Compose Stacks If you’re running multiple Docker Compose services — Nextcloud, Traefik, Gitea, Home Assistant, whatever — you probably have a patchwork of backup scripts. Or worse, no backups at all. compose-backup fixes that. One command, and every Compose project on your server gets backed up: configs, .env files, override files, and Docker volumes — all compressed into a clean .tar.gz archive you can actually restore from. ...

The Complete Docker Compose Backup Strategy for Self-Hosters You’ve got a dozen Docker Compose stacks humming along — Nextcloud for files, Vaultwarden for passwords, Gitea for code, maybe Immich for photos. Everything works great. Until it doesn’t. A corrupted disk, a bad update, an accidental docker volume rm — and suddenly you’re staring at data loss. If you don’t have a backup strategy, it’s only a matter of time. This guide walks through everything you need to back up your Docker Compose infrastructure properly. ...
