PVE not showing storage info but PBS does.

[jaysun_n]

I've set up PBS with 2 namespaces for container and node backups but am experiencing an issue where PVE isnt showing how much storage is used up on PBS but PBS does. Does anyone know how to fix this so I can see storage usage on PVE? Im assuming its an incorrectly set permission somewhere but I have no idea where or what to google for it as I keep getting results for issues other than the one I am seeing. Ive included photos showing how my PVE GUI shows no information about my PBS storage but PBS itself does.

Thanks,

Hi, jaysun_n.
I have compared your screenshots to views of my PVE and PBS and I can see that my PVE doesn't show usage of the PBS datastore in the Summary page, either. I remember that in the beginning this caught my attention as well. Now I don't really miss it because for backup administration I use PBS. My backup user has no permission to remove snapshots (backups), so I have to log into PBS anyway. I have configured this on purpose because I adhere to the principle of minimal privileges.

I don't know if not showing the usage is intentional by Proxmox developers or if my user lacks some privilege. I gave to it only DatastoreBackup role. You haven't mentioned which privileges has your user which is used to access the PBS datastore.

You can read on this subject e.g. here:

https://pbs.proxmox.com/docs/user-management.html#access-control
https://pbs.proxmox.com/docs/storage.html#restrictive-user-access-management

If you want to experiment, remember about these fragments:

Configure only minimal permissions...

One best practice to protect against ransomware is not to grant delete permissions, but to perform backup pruning directly on Proxmox Backup Server using prune jobs.

If you find (a secure ) solution, I'll gladly read about it .
