Frequently asked questions about the Managed Proxmox Backup Server

Answers to the questions we are asked most often about the Managed Proxmox Backup Server.

Everything under “Management” is empty

The management pages show content only for an active service. If the service is suspended or cancelled, they stay empty. Your data is not deleted during a suspension.

I have deleted backups, but the usage is not going down

Deleting only removes the reference at first. Only the daily Garbage Collection frees the chunks, see Retention-Settings.

My storage is filling up

1. Under Retention-Settings, check whether a keep level is still set. An empty field or a 0 switches the level off.
2. Under Content, check how many backups are marked as protected. These are never removed automatically.
3. Increase the capacity via Actions → Upgrade/Downgrade Options.

To find out in good time in the future, switch on the Storage usage and Growth rate events under Notifications.

I get no email although a job failed

Check under Notifications whether the event is switched on. All notifications are off at first. A notification only reports errors that occur after you switch it on. If the message shows up in the History as Sent, look in your spam folder.

Who can access my backups?

Access requires valid credentials and a connection from one of the public IP addresses on record. Your access user has rights only on your own datastore. If your address changes, get in touch with us.

Are my backups encrypted?

Only if you have enabled encryption on the system that creates the backups. It is off by default. The Encrypted column under Content shows whether an individual backup is encrypted. How to set it up is described in Connecting your own Proxmox VE.

I have lost my encryption key

Then the backups encrypted with it can no longer be read. We do not hold a copy. Create a new key in Proxmox VE, keep it separate from the server and start a new series of backups.

Can I retrieve individual files from a backup?

Not through the Client Area. Add the datastore to your own Proxmox VE and use the file restore there.

Can I check whether my backups can be restored?

Yes. A verify job checks the data chunks. You can only be completely sure once you actually restore a backup, for example with a weekly scheduled restore into a standby machine.

What happens to my data when I cancel?

When the service ends, the datastore is removed. Retrieve what you want to keep beforehand, for example with a sync job in the push direction, see Locations and Sync Jobs.

Can several Proxmox VE clusters share one datastore?

Yes, with namespaces: one namespace per cluster or site, created in the Client Area under Content and entered on the storage in Proxmox VE. Retention and verification apply to the whole datastore including all namespaces; sync jobs can be limited to one namespace.
