One of the most visited pages on my blog is about how to automatically backup Docker volumes. In that post I use the Docker image blacklabelops/volumerize. Unfortunately that image is deprecated since March 2019 and not longer maintained. Under the hood the volumerize image is using the GNU program duplicity, which is an awesome software, but also has it’s downsides. Especially the model of full backups and incremental backups comes from a time where backups where mainly made to tapes (just append new files all the time).
