[pve-devel] About PVE Backup Integration Guide

Tue Apr 1 09:02:04 CEST 2025

Finally, we can install packages from pvtest repository.

We have gone through plugins POD material; we have few questions from very little understanding about plugins:

  1.  Storage plugin
     *   What is the main purpose of storage plugin?
     *   Do we need to implement our own storage plugin? Which all functions we need to implement?

  1.  Backup Provider plugin
     *   What is the main purpose of backup provider plugin?
     *   Do we need to implement our own backup provider plugin? Which all functions we need to implement?
     *   Which model this provider refers to - push model or pull model?
     *   It looks like we have two main callback functions - job_hook() and backup_hook(). Who calls these functions and when do they get called?
     *   backup_get_mechanism() - This function needs to be called by external backup product?
     *   backup_vm() - This function needs to be called by external backup product? Does it support all disk formats and backed storages?

Regards

Prashant

Yes, you cannot use the enterprise repository without a valid subscription. But you don't need it, because for testing you only need the newer package versions from the pvetest repository.

What if you run "apt --fix-broken install"? If that doesn't help, please share the output of "apt policy proxmox-widget-toolkit".
