New home

I've been self-hosted a few services for my daily needs, and I choosed Hetzner because of their's pricing.

But now after I know Contabo, I will move my services to Contabo, because it's cheaper and more powerful.

I can reduce the server cost for about 30%. Neet.

But I don't want to lose my data. And I don't want to spent a lot of time migrate things either.

Luckily, all of my projects was deployed using Docker. If you don't know Docker, now is good time to start because it's awesome.

Moving data

Let's say I want to move from server A (Hetzner) to server B (Contabo)

And my jobs now are:

1. Generate ssh key (ssh-keygen -t ed25519) and add public key to server B ~/.ssh/authorized_keys file.
2. rsync -av my projects from A to B
3. Find the right directory where Docker bind volumes with docker inspect <container_name> | grep "Source"

If you want to archive database

1. tar cvf everything inside .../_data
2. rsync tar files to new server
3. tar xvf them to new ~/backup directory

1. Build and up docker services
2. Stop services
3. rsync backup directory to binded directory path from step 3
4. Repeat step 4 for other services

After that you can safely delete the extracted directories. Install nginx and copy config files from A -> B.

You might want to keep the tar file for a bit longer to prevent issues.
