Is there Support for "Proxmox Backup Server"?

tl;dr
Yes, there are apps for both platforms: AppStore and Google Play to manage your PBS.

Why is there no support for Proxmox Backup Servers in ProxMate?

ProxMate obtains all data displayed in the app from Proxmoxes programming interface (API). Unfortunately, the API of the backup server is fundamentally different from the normal proxmox servers/nodes.

In my opinion, support for the backup server in ProxMate would therefore be difficult to implement for the user and would make it necessary to provide every view in the app twice - once for PVE and once for the backup server. This is very error-prone and difficult to maintain/expand, which is why I decided to develop a separate app for the backup server.
