Managing Remotes


A remote refers to a separate Proxmox Backup Server installation and a user on that installation, from which you can sync datastores to a local datastore with a Sync Job. You can configure remotes in the web interface, under Configuration -> Remotes. Alternatively, you can use the remote subcommand. The configuration information for remotes is stored in the file /etc/proxmox-backup/remote.cfg.

Add a remote

To add a remote, you need its hostname or IP address, a userid and password on the remote, and its certificate fingerprint. To get the fingerprint, use the proxmox-backup-manager cert info command on the remote, or navigate to Dashboard in the remote's web interface and select Show Fingerprint.

# proxmox-backup-manager cert info |grep Fingerprint
Fingerprint (sha256): 64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe

Using the information specified above, you can add a remote from the Remotes configuration panel, or by using the command:

# proxmox-backup-manager remote create pbs2 --host pbs2.mydomain.example --userid sync@pam --password 'SECRET' --fingerprint 64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe

Use the list, show, update, remove subcommands of proxmox-backup-manager remote to manage your remotes:

# proxmox-backup-manager remote update pbs2 --host pbs2.example
# proxmox-backup-manager remote list
│ name │ host         │ userid   │ fingerprint                               │ comment │
│ pbs2 │ pbs2.example │ sync@pam │64:d3:ff:3a:50:38:53:5a:9b:f7:50:...:ab:fe │         │
# proxmox-backup-manager remote remove pbs2

Sync Jobs

Add a Sync Job

Sync jobs are configured to pull the contents of a datastore on a Remote to a local datastore. You can manage sync jobs in the web interface, from the Sync Jobs tab of the Datastore panel or from that of the Datastore itself. Alternatively, you can manage them with the proxmox-backup-manager sync-job command. The configuration information for sync jobs is stored at /etc/proxmox-backup/sync.cfg. To create a new sync job, click the add button in the GUI, or use the create subcommand. After creating a sync job, you can either start it manually from the GUI or provide it with a schedule (see Calendar Events) to run regularly.

# proxmox-backup-manager sync-job create pbs2-local --remote pbs2 --remote-store local --store local --schedule 'Wed 02:30'
# proxmox-backup-manager sync-job update pbs2-local --comment 'offsite'
# proxmox-backup-manager sync-job list
│ id         │ store │ remote │ remote-store │ schedule  │ comment │
│ pbs2-local │ local │ pbs2   │ local        │ Wed 02:30 │ offsite │
# proxmox-backup-manager sync-job remove pbs2-local

To set up sync jobs, the configuring user needs the following permissions:

  1. Remote.Read on the /remote/{remote}/{remote-store} path

  2. At least Datastore.Backup on the local target datastore (/datastore/{store})


A sync job can only sync backup groups that the configured remote's user/API token can read. If a remote is configured with a user/API token that only has Datastore.Backup privileges, only the limited set of accessible snapshots owned by that user/API token can be synced.

If the remove-vanished option is set, Datastore.Prune is required on the local datastore as well. If the owner option is not set (defaulting to root@pam) or is set to something other than the configuring user, Datastore.Modify is required as well.

If the group-filter option is set, only backup groups matching at least one of the specified criteria are synced. The available criteria are:

  • backup type, for example to only sync groups of the ct (Container) type:
    # proxmox-backup-manager sync-job update ID --group-filter type:ct
  • full group identifier
    # proxmox-backup-manager sync-job update ID --group-filter group:vm/100
  • regular expression matched against the full group identifier

The same filter is applied to local groups for handling of the remove-vanished option.


The protected flag of remote backup snapshots will not be synced.

Bandwidth Limit

Syncing a datastore to an archive can produce lots of traffic and impact other users of the network. So, to avoid network or storage congestion you can limit the bandwidth of the sync job by setting the rate-in option either in the web interface or using the proxmox-backup-manager command-line tool:

# proxmox-backup-manager sync-job update ID --rate-in 20MiB
