Backing up your server is essential, and Proxmox Backup Server (PBS) makes it straightforward and reliable. Here’s a step-by-step guide to get you started:

Step 1: Set Up Proxmox Backup Server

  • Install PBS on a dedicated machine or virtual environment. You can download the ISO and follow the installation guide here.
  • Once installed, access the PBS web interface at https://<PBS_IP>:8007 and log in with your credentials.

Step 2: Configure a Datastore

  • In the PBS web interface, create a datastore to store your backups:
    • Navigate to Datastore > Add Datastore.
    • Provide a name and specify the storage path.

Step 3: Connect PBS to Proxmox VE

  • In your Proxmox VE web interface:
    • Go to Datacenter > Storage > Add > Proxmox Backup Server.
    • Enter the PBS IP address, port (default is 8007), and credentials.
    • Select the datastore you created earlier.

Step 4: Create a Backup Job

  • In Proxmox VE:
    • Navigate to Datacenter > Backup > Add.
    • Choose the VMs or containers you want to back up.
    • Select the PBS storage as the target.
    • Configure the schedule and retention settings to suit your needs.

Step 5: Run the Backup

  • You can manually trigger a backup by selecting the backup job and clicking Run Now.
  • Alternatively, backups will run automatically based on the schedule you set.

Pro Tips for Effective Backups

  • Retention Policies: Set up different retention policies for daily, weekly, and monthly backups to optimize storage.
