How to Sync Data Between Two Proxmox Backup Servers (PBS)

 Prerequisites

• Both servers must be running Proxmox Backup Server.

• Network access between both servers (default PBS port: 8007).

• Administrative access to both PBS servers.

• Datastore configured on both servers.

 Step 1: Add Remote PBS Server

On the destination PBS (where you want the data to be synced to):

1. Log in to the PBS web interface.

2. Go to: Datastore ➜ Remotes ➜ Add.

3. Fill in the following:

   • Remote ID: A name (e.g., source-pbs)

   • Host: IP or hostname of the source PBS

   • Port: 8007 (default)

   • Username: root@pam or an API token user

   • Password or API Token

Click Add and test the connection.

Step 2: Create a Sync Job

Still on the destination PBS:

1. Go to: Datastore ➜ Sync Jobs ➜ Add.

2. Select the following:

   • Remote: The remote PBS you added earlier

   • Remote Store: The datastore name on the remote PBS

   • Local Store: The local datastore where backups will be synced

   • Schedule: e.g., daily at 2:00 AM

   • Options:

     • Enable Sync Namespace if you use namespace-based backups

     • Enable Remove Vanished if you want to delete backups removed from source

3. Click Create.
   
   
   
   

Step 3: Run and Verify

• • Manually run the sync job once to verify.

  • Go to Datastore ➜ select your local store ➜ check if backups are syncing properly.
