Get Backup Nodes via API

[NothingTV]

Hi there,

I have another question about the API, I see that there is an note endpoint, but it does not provide notes of the vm, I already know, that they are stored in qemu-server.conf.blob, is there a way to access this via API?

Best regards

It is the description property of the VM config:

https://pve.proxmox.com/pve-docs/api-viewer/#/nodes/{node}/qemu/{vmid}/config

Thank you, but I talk about the Proxmox Backup Server API

the notes of pbs are independent of the vm notes on the pve side

there are group-notes:

https://pbs.proxmox.com/docs/api-viewer/index.html#/admin/datastore/{store}/group-notes

and snapshot notes

https://pbs.proxmox.com/docs/api-viewer/index.html#/admin/datastore/{store}/notes

I know both endpoints already, but I need the notes of the actual Backup that is stored in the qemu-server.conf.blob, is there a way to read this via API? Because the PBS does not store them in the group-notes.

you could use: https://pbs.proxmox.com/docs/api-viewer/index.html#/admin/datastore/{store}/download-decoded

to download the config and parse it yourself, but from pbs perspective, it's just some file and it does not know about PVE vm configs and does not have the ability to parse those
note that that only works for unencrypted backups, since PBS does not have access to the encryption key (only the client, so PVE, has that)

if you want to access that from the PVE side, you could use https://pve.proxmox.com/pve-docs/api-viewer/index.html#/nodes/{node}/vzdump/extractconfig to exctract the config from a pbs

Can you explain how this works?
If I try this via HTTP I get "null" via CLI this:
```
pvesh get /nodes/node-name/vzdump/extractconfig --volume="volume-name"
unable to parse volume ID 'volume-name'
```

 

[dcsapak]

the volume name must be the "volid" of the backup e.g. "pbs-storage:backup/vm/100/2024-06-18T12:26:27Z"
