set up rsync server
To set up an rsync backup server on Arch Linux for use with a ReadyNAS, follow these steps:
1. Install rsync
Install rsync on your Arch Linux system:
sudo pacman -S rsync
2. Create a Backup Directory
Choose a directory to store the backups, e.g., /backup, and ensure proper permissions:
sudo mkdir /backup
sudo chown rsync:rsync /backup
sudo chmod 700 /backup
3. Create a Dedicated User
Create a user (e.g., rsync) for secure file transfers:
sudo useradd -m -d /home/rsync -s /bin/false rsync
sudo passwd rsync
4. Configure rsyncd.conf
Edit or create /etc/rsyncd.conf for your rsync server configuration:
sudo nano /etc/rsyncd.conf
Example configuration:
uid = rsync
gid = rsync
use chroot = yes
max connections = 4
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
[backup]
path = /backup
comment = ReadyNAS Backup
read only = no
auth users = rsync
secrets file = /etc/rsyncd.secrets
5. Set Up Authentication
Create a secrets file for authentication:
sudo nano /etc/rsyncd.secrets
Add a line with the username and password (e.g., rsync:yourpassword):
rsync:yourpassword
Set proper permissions:
sudo chmod 600 /etc/rsyncd.secrets
6. Start the rsync Daemon
Enable and start the rsyncd service:
sudo systemctl enable rsyncd.service
sudo systemctl start rsyncd.service
7. Configure ReadyNAS
On your ReadyNAS:
- Go to Backup settings.
- Select Remote: Rsync Server.
- Enter the Arch Linux server’s IP, module name (
backup), username (rsync), and password (yourpassword).
8. Test the Backup
Manually test connectivity from ReadyNAS or any client:
rsync rsync://rsync@<your-arch-linux-ip>/backup
If this lists the backup directory, your setup is ready.
