On Digital Ocean a persistent volume has a folder `lost+found` by
default. This script stops throws error messages because it can't remove
that folder if we don't add `-r` flag.
`rsync` is faster on multiple runs. The `--update` flag will only
download newer images and does not overwrite existing files. Thus, it will
only download missing images.
@appinteractive it's troublesome to add the SSH private key via
environment variable. You have to convert newlines to spaces and convert
them back - which I think is error prone. I hope we can transfer the
private key file on to our deployed container later on.
The idea is to import/dump the remote database via SSH, restore it to
the local mongodb, export .json collections to a shared volume and
import the json collections with cypher-shell.
