This script automates the backup of Proxmox data to a designated Proxmox Backup Server (PBS).

• Proxmox Backup Client installed
• Configuration file located at /etc/backup_pbs.conf with necessary environment variables

1. Clone the repository and navigate to the project folder:

   git clone https://github.com/highTowerSU/pbs-backup.git
   cd pbs-backup

2. Run the installation script to copy files to the appropriate locations:

   sudo bash ./install.sh

   This will:

   • Copy the main script to /usr/local/bin/backup_pbs.sh
   • Copy the configuration file to /etc/backup_pbs.conf if it doesn't already exist.

3. Edit the configuration file: Open /etc/backup_pbs.conf and set your Proxmox Backup Server details:

   PBS_PASSWORD='your_password_here'
   PBS_FINGERPRINT='your_fingerprint_here'
   PBS_REPOSITORY='user@server@hostname:backup'
   PBS_NS='your_namespace_here'
   PBS_ARCHIVES='root.pxar:/ c.pxar:/mnt/c/'
   

Run this command to download and execute the install script directly (options from install sh working):

sh -c "$(curl -fsSL https://raw.githubusercontent.com/highTowerSU/pbs-backup/main/webinstall.sh)"

Run the script manually or set it up as a cron job for regular automated backups.

# Manual run
/usr/local/bin/backup_pbs.sh

Add to cron:

30 23 * * * /usr/local/bin/backup_pbs.sh

If you're running this on WSL, you may want to exclude the following directories. To do so, create a file at /.pxarexclude with the following content:

/proc/
/sys/

If the Proxmox Backup Client (proxmox-backup-client) is not installed, run the following commands:

sudo apt update
sudo apt install proxmox-backup-client

If you encounter repository issues, create the file /etc/apt/sources.list.d/proxmox-backup-client.list with the following content:

deb http://download.proxmox.com/debian/pbs bullseye main

Then update your package list again with:

sudo apt update
