dvb (Docker Volume Backup)

Docker Volume Backup is a cli tool I use to backup my data on my docker servers. I have mixed luck with cron trying to chain together commands to get them to work the way I want. I want also wnt to see the notifications come in when the backups are done so I can keep an eye on things.

Requirements

1. Have Go 1.19 installed or newer (no plans to release compiled versions at this time)
2. Have Docker CLI installed (This was built against version 20.10.14)

Install

go install github.com/jtom38/dvb@latest

Config

Backup:
  # This defines that the containers come from Docker
  Docker:
      # Name of the container
    - Name: webdav-app-1
      # Where inside your container is the data that needs to be backed up
      Directory: /var/lib/dav
      Tar:
        # if $PWD is used, we convert this to your working directory as you expect.
        Directory: $PWD
        # {{date}} is replaced with a date code value 20221217
        Pattern: webdav-data-{{date}}
        Extension: tar
  
# Once its backed up, what do we do with the file?
# If you want to leave it in the current directory it was made, you don't need this block
Destination:
  Retain:
    # This tells us to remove files older then 10 days
    # if you want to retain everything, set this to 0
    Days: 10

  # Local flag defines that this will move data within the same host
  Local: 
    # Defines what directory that it will move to.
    # The container name will be append to the path
    Path: /mnt/nas/backups

# If you want this to send you alerts, right now discord is only supported
# If you don't want discord alerts, remove this block
