A simple Docker volume backup tool.

Introduction

Essentially, this is an automated and configurable backup tool built around rsync.

The Basics¶

Nautical runs on a CRON schedule to:

1. Stop the container (if configured)
2. Run the backup via rsync
3. Restart the container (if stopped)

⚗️ Need more control? There are many more options available via variables and labels.

Sample Configuration¶

Nautical requires almost no configuration when container volumes are all in a folder matching its container-name within the source directory. Of course, we can use variables and labels to override these defaults.

Let's take a look at an example:

Container Name	Source Data Directory	Destination Data Directory
homepage	/opt/docker-volumes/homepage	/mnt/nfs-share/backups/homepage
trilium	/opt/docker-volumes/trilium	/mnt/nfs-share/backups/trilium
dozzle	N/A (no data folder)	N/A (no backup needed)

Here is how Nautical fits into the Sample Configuration
