[pve-devel] About PVE Backup Integration Guide

[Prashant Patil]

Instead of making such multiple hops, can we have APIs exposed by Proxmox VE which we can use? E.g. API to get consistent snapshot-access to a virtual disk.

This way we have better control on monitoring jobs, API contracts are decided, it is also easy to troubleshoot issues on each side, etc. Let me know your thoughts on this. With Proxmox VE REST APIs, we already have several APIs for nodes/VMs management.



Regards

Prashant

Yes, the API is designed for the integrated backup/restore tasks on the Proxmox VE side. The implementation of the API methods will serve as a bridge to your backup server.



If you really want, nothing prevents to manage your own jobs from the server side. You'd just need to issue the relevant API calls via the Proxmox VE REST API, e.g.:

1. Your job on the server side decides to run a backup.

2. It sends the 'vzdump' API call to the Proxmox VE node.

3. The Proxmox VE node will call the methods of your backup provider API implementation.

4. Inside these methods, you get access to the data that can be transferred to your backup server.
