Restore a Docker volume from a local tar file

#docker #tar #backup

Use a temporary container to restore files from a local tar file into a Docker volume

Works with backups created by following: Backup a Docker volume to a local tar file 

docker run --rm \
-v <volume>:/data -v $(pwd):/backup \
ubuntu tar xvf /backup/backup.tar -C /data --strip 1
  • the --rm switch will clean up the container when the command completes
  • replace <volume> with the Docker volume name
  • replace ubuntu with another distribution if you want

Example 

docker run --rm \
-v paperless_media:/data -v $(pwd):/backup \
ubuntu tar xvf /backup/backup.tar -C /data --strip 1
