Rdiff-backup is a popular backup tool that allows users to create and maintain remote backups of their data. If you are using Alpine Linux and want to install Rdiff-backup, this tutorial will guide you through the process. Here are the steps:
The first step is to update and upgrade your Alpine Linux system to ensure that everything is up to date. To do this, open the terminal and type:
apk update
apk upgrade
This will update the package list and upgrade all installed packages to the latest version.
Before installing Rdiff-backup, you need to install some required packages. To install these packages, type:
apk add --no-cache rdiff-backup openssh-client bash
This will install Rdiff-backup, OpenSSH Client, and Bash.
To use Rdiff-backup, you need an SSH key pair to allow Rdiff-backup to access your remote servers. To create an RSA key pair, type:
ssh-keygen -t rsa
Follow the prompts to create the RSA key pair. By default, this will create a ~/.ssh/id_rsa private key and a ~/.ssh/id_rsa.pub public key.
The next step is to copy the public key to the remote server to allow Rdiff-backup to access it. To do this, type:
ssh-copy-id remote_server_username@remote_server_ip_address
Replace remote_server_username with the username of the remote server and remote_server_ip_address with the IP address of the remote server.
The last step is to configure Rdiff-backup to enable backups. To do this, create a backup configuration file, for example:
mkdir -p ~/backups/my_backup
vim ~/backups/my_backup/config
Add the following settings in the configuration file:
#!/bin/bash
export PATH=$PATH:/usr/local/bin
RDIF="/usr/bin/rdiff-backup"
SSH="/usr/bin/ssh"
SSH_OPTIONS="-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o LogLevel=ERROR -o Compression=no"
SOURCE="user@server:/path/to/source/folder/"
DEST="~/backups/my_backup/"
LOG="~/backups/my_backup/backup.log"
$RDIF -v5 --exclude-device-files --exclude "/var/www/backup/*" --remote-schema 'ssh -C %s -p %p rdiff-backup --server' $SOURCE $DEST > $LOG 2>&1
Replace user@server:/path/to/source/folder/ with the folder on the remote server you want to backup and ~/backups/my_backup/ with the directory where you want to store the backups.
To run Rdiff-backup, type:
~/backups/my_backup/config
This will start the backup process. You can also add this to a cron job to run it automatically at a specific time.
Congratulations! You have successfully installed Rdiff-backup on Alpine Linux Latest and created a backup configuration.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
