[jasonacox]

Here are the steps need to copy an existing database to a new host.

First, make sure you set up Powerwall-Dashboard on the new host. Setup instructions: https://github.com/jasonacox/Powerwall-Dashboard?tab=readme-ov-file#setup

Old Host

Next, on the OLD host run:

cd Powerwall-Dashboard

# Stop influxdb to ensure nothing is being written
docker stop influxdb

# Create an archive of the influxdb database
sudo tar -zcvf snapshot.tgz influxdb 

# Restart influxdb  
docker start influxdb

Copy Backup to New Host

You will need to copy the snapshot.tgz file to the new host.

New Host

On the NEW host you will run:

cd Powerwall-Dashboard

# Stop the full stack - this is important
./compose-dash.sh stop

# Restore the database to the local host using the local owner (user)
sudo tar --no-same-owner -zxvf snapshot.tgz 

# Restart the stack
./compose-dash.sh up -d

Give the stack a minute to restart and you should see your old data on your new host.
