What is SCP?

SCP stands for Secure Copy Protocol. With it you can transfer files from one machine to another with ssh.

But this tool uses rsync, basicly it is the same thing but in different package.

SSH Key

To transfer files with ease and secure, you need to provide a private key to DBackUp and a public key on your Destination Remote.

How do I obtain those keys?

• You need openssh installed on your machine.
• Then use (Works on Linux and Windows):

  ssh-keygen -t ed25519 -f /path/to/folder/key_name
  

You will get two file in the folder you have choosed:

1. key_name DBackUp needs it
2. key_name.pub Destination machine needs it

What do I do with those keys?

For key_name.pub

1. you need to add to end of authorized_keys file on the destination machine. it is located in ~/.ssh/ on Linux

For key_name

1. You need to copy it to the directory where DBackUp docker-compose.yml is.

2. Bind it to the container in volume: like

   volume:
       - key_name:/app/ssh_key
   

Destination Remotes

Destination Remote the remotes that would recive the backups

You can add them into your .env file under REMOTE_ADDRESSES variable:

REMOTE_ADDRESSES=root@some.random.ip.address:/destination_folder

If you want multiple Destination Remotes, you can separate them with comma ,

Every Destination Remote should have rsync installed on them.
