Cross platform backup and Restore from Windows to LightSail local instance

I have a Windows Server 2019 installation with OpenRMR 6.1. I’ve installed OpenEMR on a Lightsail local instance in Ubuntu 20.04.1.

How can I restore a backup of my Windows instance to a LightSail instance on Ubuntu? I have data on the Windows instance and I want to import it to the LightSail instance using backup and restore.

I am trying to follow this link but I’m confused about the docker bit and the container where openERM is in.

I’m also looking at this link but am lost about what to do.


The second link to Ben’s blog post is your best bet. Is there a particular step that’s giving you problems? You’ll want to start by creating a backup via the GUI on your Windows instance.

Actually I wanted to know if my idea on cross platform backup and restore is doable.

I’ll try Ben’s Blog.


I did Create and download a full backup, and Download configuration data. I now struggling through Ben’s doc.

The difficult thing in Ben’s doc is the copy procedure. I get an error: copying between containers is not supported.


You mentioned you have a local lightsail instance installed already, so are you at or past the “Copying file to docker database container” step?

No, not there as yet as I still get this error: copying between containers is not supported. Looks like a permissions issue. Will Google the error to see how to modify permissions.

Y’know, I’ve never tested it, but it seems to me that you could expose the docker’s MySQL port and then conceal it again by editing the docker-compose file and doing repeated ups with no down.

No guarantee it wouldn’t delete data if you tried it, I’m not totally familiar with what happens when you up a running composition.

If you’re copying from Windows, you have to put the path in quotes, else Docker will think “c:” is a container.

Thanks for the tip. I didn’t find any of my Google searches saying use “c”. However, I did see docs that said Docker treated the c:/ as a container.

Jason suggested I use “c:” so I’ll try it tomorrow and let you know how it goes.

No, put quotes around the path. If you were trying something like:

docker cp C:\openemr.tar.gz $(docker ps | grep _openemr | cut -f 1 -d " "):/var/www/localhost/htdocs/openemr/

change it to:

docker cp "C:\openemr.tar.gz" $(docker ps | grep _openemr | cut -f 1 -d " "):/var/www/localhost/htdocs/openemr/

Ok. Thanks for the updates. I’ll try it and let you know.

These are my Docker containers

I want to copy c:\openemr.sql.gz and c:\openemr.tar.gz to the Docker containers so I can import the data to a fresh installation of OpenEMR that I installed from lightsail.

This command didn’t work.

docker cp ‘C:\openemr.sql.gz’ e8a6c9e3c1dc:/home

hc4admin@openemrlightsail:~$ sudo docker cp ‘C:\openemr.sql.gz’ e8a6c9e3c1dc:/home
[sudo] password for hc4admin:

I’m trying to follow this Blog:
Open EMR Backup and Restore Docker Procedure
And I’m stuck at copying the gz files.

Have you tried double quotes? Is that path actually where your openemr.sql.gz file is?

Yes, I did use “”. Here is my configuration. C:/*.gz is the actual path.

I have OpenEMR 6.1 installed on Ubuntu in a Docker container. I followed the instructions in this page.

# OpenEMR Cloud: Do-It-Yourself Lightsail Edition

And I used this script to install Docker and OpenEMR 6.1

curl -L > ./
chmod +x ./ && sudo ./

From a Windows 10 PC, I SSH to Ubuntu and run the command
sudo docker cp “C:\openemr.sql.gz” e8a6c9e3c1dc:/home and got this result
copying between containers is not supported

Have I made a mistake in the cp command?


My goal is to restore the gz files I backed up from my Windows installation of OpenEMR 6.1 as I want to migrate from Windows server 2019 XAMPP platform to a linux (Ubuntu 20.04) one. I have a May 2 deadline to go live with Open EMR 6.1. So I’m testing now.


You have to first get the files onto the Ubuntu host. scp is the command you want.
