vi7al/netatalk-timemachine repository overview

⁠netatalk-timemachine

Alpine Linux based Netatalk AFP fileserver for the Apple Time Machine backups and more

Based on:

• Alpine Linux⁠
• Netatalk⁠

⁠Run

Running the service via Docker compose:

# Overrride mountpoint for timemachine data volume if needed. Default: `/mnt/timemachine`
# export TIMEMACHINE_VOLUME=/some/path
# Override container name prefix
# export COMPOSE_PROJECT_NAME=myapp
docker-compose -f netatalk-compose.yml up -d

⁠Use

⁠Mac OS Time Machine disk

• Go to Finder, press CMD+K, insert afp://<your-server-address>/
• Provide credentials, defaults are:
  • username: tmbackup
  • password: tmbackup
• Go to Time Machine Preferences pane, press Select Disk, choose the network drive connected in the previous step, enter credentials again if asked
• Sometimes Mac OS doesn't show "unsupported" or non-Apple Time Machine network drives, but you can easily change that with one Terminal command:

  defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
  

  Copy

⁠Build, tag and push

Note: the example below is using my Docker HUB username and Project versioning

export TM_VERSION=0.3
docker build -t vi7al/netatalk-timemachine:${TM_VERSION} .
docker tag vi7al/netatalk-timemachine:${TM_VERSION} vi7al/netatalk-timemachine:latest
docker push vi7al/netatalk-timemachine:${TM_VERSION}
docker push vi7al/netatalk-timemachine

⁠Configure

⁠Add share

• open afpd config file in editor:

  docker exec -it <container_name> vi /etc/afp.conf
  

  Copy

• add configuration section for the share at the end of the file. Example is below

  [Time Machine vol2]
  path = /timemachine/vol2
  valid users = tmbackup
  time machine = yes
  # the max size of the data folder (in Kb)
  vol size limit = 536870912
  

  Copy

• force AFPd to re-read the config

  docker exec -it <container_name> pkill -HUP afpd
  

  Copy
