Hi,
I have to use some non-well-made containers running a proprietary database
product, where the data-directory can not be separated easily from the rest
of the container. So modified state is not only stored at some specific
paths, which I could re-direct to volumes, but spread over the whole
file-system.
Is there an easy way to backup such a container as a whole?
It sounds like podman-container-{checkpoint,restore} could be something for
your use case (
https://docs.podman.io/en/latest/markdown/podman-container-checkpoint.1.html
).
Kind regards,
Valentin
I already tried to export the container to an image and later on
re-import
it, however it seems during this process some metadata is lost - when I try
to start that re-imported container, podman complains about missing start
script/commands.
I already found podman clone, however on my system (fedora 35) it doesn't
seem to be available.
Are there maybe other ways to duplicate/export an existing container and
keeping the clone in a working state?
Thanks, Clemens
