[pve-devel] About PVE Backup Integration Guide

[Prashant Patil]

Basically, the backup/restore tasks will be managed through our backup solution. So, all we needed is VM config which can be fetched through PVE REST API and a API to get access to consistent disk image which can be then transferred to backup storage that we support. But it looks like this is not possible with current design of provider APIs.

Is there any chance of developing new library which can provide access to consistent disk image in near future?

Regards,
Prashant

There are no endpoints in the Proxmox VE REST API for setting up backup access to a guest or similar. And the backup provider API is simply not designed for this, but to be fully integrated in Proxmox VE. What you can do is leverage Proxmox VE REST API for the backup/restore tasks, but not just for parts of such tasks.
